I was playing minecraft for the last few days, started it this morning and everything worked. When I got back from Uni, I got this error (title) when I try to launch the game (after login in, when I press "play") .
Also tried to install it on another machine, which is also running linux mint, and I had the exact same error:

this looks more like an error in the build
if it can't find its entry function, it is missing
Also seeing this error with the latest Linux Minecraft.jar on fedora 26. Just started this morning. It was working ok last night.
java.lang.ClassNotFoundException: net.minecraft.client.main.Main
Same error message form the 1.6.82-j launcher on my Linux Mint 17.3 machine this evening after everything was working this morning.
Tried using CrossOver to install the Windows version, with 1.6.82 launcher. Same error message from that one.

Can run 1.12.2 vanilla using MultiMC, so the problem must be with the 1.6.82-j launcher on Linux.
This error seems to affect all mc-(java)-versions (tested some versions down to 1.7.10) exept the newest snapshot
yea 1.7.10 and 1.8.9 dont work for me and im on 0SX 10.7.5 so must be something to do with servers as they updated the new launcher today i guess we just wait.
Same thing for me on Linux Mint 18.1 (Serena). Worked yesterday.
I'm wondering whether it is an Ubuntu package upgrade that caused it. Have you guys also updated Ubuntu packages since it last worked?
i doubt its do with anything that we have to update etc, we are all using the alternative download. maybe when they updated the new launcher, it caused problems with the old launchers for Linux, and MAC
@unknown No updates on my end in-between the launcher working and the launcher not working.
Yesterday I played without any problem, but today it looks like the game is completely ruined, after a minor update (I almost didn't see it on the console) of the launcher (to 1.6.82-j).
I play on linux fedora 26, on a computer without GPU.
When I click play, only two lines show up befor the game crashes (whenever we can tell it starts) :
??OpenJDK 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
Error: Could not find or load main class net.minecraft.client.main.Main??
I tried re-installing the launcher and game data, nothing changed.
Then I even removed anything named minecraft (case insensitive) on the hard drive, re-installed everything, I still get this error.
Worked this morning, but now getting this same error. Using Ubuntu 14.04. Updated to latest java (1.8.0_152) and renamed ~/.minecraft directory and still getting this error.
Looks like an update occurred on my system in the interim: chromium-codecs-ffmpeg-extra:amd64 62.0.3202.62-0ubuntu0.14.04.1204
Question: If the problem is caused by an automatic launcher update, is there a way we can use the prior version of the launcher?
As a temporary workaround you can use the test version of the new Launcher. That still seems to have an issue with modded versions though.
Getting the same errors here on every version I've tried apart from the latest snapshot
1.12.2 fail
1.12.1 fail
1.12 fail
1.11.2 fail
1.11 fail
1.10 fail
Trouble is I'm playing on a server that runs 1.11.2 so the fact the latest snapshot is working is not much help
I was getting the same problem with the launcher not working. it had an update this afternoon and is now not even generating an error for me

Hope this info helps.

As a temporary workaround you can use the test version of the new Launcher. That still seems to have an issue with modded versions though.
@unknown Unfortunately, this does not work on Linux Mint 18.1 (or Ubuntu 16.04) due to wrong version of libICU. Would be nice if we could compile the launcher ourselves.
./launcher: error while loading shared libraries: libicui18n.so.57: cannot open shared object file: No such file or directory
Archlinux is also affected. However it should just say Linux in general as all distros are affected.
Hi, not sure whether this should form a separate thread, but this issue is also affecting Windows XP (yes I know I should get a new PC), but appears to have been fixed for Windows 10.
Windows XP SP3
Launcher 1.6.82
I have tried to do a full remove and reinstall, but to no avail.
According to this forum post, it also affects Windows 7.
Problem for me as well:
Ubuntu 16.04.3 (LTS) 64-bit
Launcher version 1.6.82-j
Can't launch anything except for the latest snapshot version.
Launcher version 2.0.1005 does not work, as the library libicui18n.so.57 is not available on the system.
i have that problem too 😞
OS: GNU Linux (Debian) - Desktop Enviorment - XFCE4
MC Launcher Version: 1.6.82-j (i am still using the old launcher, but that is not the problem)
it only works on snapshots, but i need 2 go on 1.11.2 because my friends have a server on that version.
it says:

Judging from a comment in this forum thread, a possible workaround might be to use OneClient. Hopefullt it is not malware. Anybody have any experience with it?
vanilla 1.12.2 does not load at all. errors out with:
Error: Could not find or load main class net.minecraft.client.main.Main
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
If I load snapshot 17w43a I can get into game, but there is no sounds (AT ALL), and I cannot play online.
EDIT: I have tried un/re-install. Deleting .minecraft folder. Redownloading and un/re-installing. With and without snapshot. And updating Java. Error process above EDIT still existent.
@Kristian Spangsege "According to this forum post, it also affects Windows 7." That would be me, and I can confirm I have this issue (as described in the forum post) on Windows 7, on both the 'old' and 'new' official launchers. The problem does not occur using the Twitch (Curse) app to download and launch the game.
Edit: Please add Windows 7 to the Environments, and every version to the Affected Versions? I've tried 1.6.4, 1.7, 1.8, 1.9.8, 1.12 and 1.12.2. The only unaffected version is the latest snapshot, 17w43a.
Copy pasta from my forum post:Except for the java.io.IOException: Stream Closed lines, I get the exact same issue. Nothing on my end has changed since it last worked (24 hours ago), and nothing I do solves the issue.
Quick list of the things I've tried:
Removing Java arguments
Re-installing Java
Re-installing Minecraft
Using a different launcher
Using a different version of Minecraft
Making sure there is no permission nonsense going on (running as admin, make sure folders & files are read- and write-able)
And then I found out that the ONLY version of minecraft I can run is the latest snapshot, 17w43a. I'm assuming Mojang has messed something up here, as this started happening right around when that snapshot got released, and nothing on my end has changed, and nothing I do fixes it.

(I was using optifine 1.8.9 there, but it is the exact same, aside from the version name, for any unmodified version of minecraft.)
Java 8 Update 151, Windows 7.
I had a bit of a chat with a friend (nicknamed SnuRRe) who doesn't have the issue about this, trying to hopefully get somewhere with it, and while completely unsuccessful when it comes to trying to fix it, it seems that using the Curse launcher (twitch app) to install and launch minecraft works, so that's a work-around for some that just really want to play the game for the time being I guess. Assuming no proper solution or official statement has been made regarding this since I'll probably continue trying later and post if I find anything noteworthy, but that's all I've got for now.

Minecraft is not working anymore .... so sad and nice not work from Mojang....
Windows 8/8.1 (at least for me) is also affected by this, considering the newest snapshot is also the only thing that works for me I'm guessing I'm having the same exact issue.
I don't know what orphaned objects are but just in case: whenever I reopen Mc after using the latest snapshot a lot of orphaned objects are cleaned up according to the logs(after attempting to launch another version, I attempted this with 1.8.9), they also state that the .jar of the snapshot can't be found or something along those lines, I can't access my pc at the moment so I can't paste the full log. Finally the snapshot doesn't actually make any sounds even though Mc is in the volume mixer. Though that part is probably just a separate bug, not sure.
Edit: in case this helps: the orphaned objects are just lines of letters and numbers, again, I have no knowledge of orphaned objects so I'm just saying this in case this helps.
Pretty sure the sounds are a separate issue, since there's also no subtitles.
I can run the current snapshot all I want, but cannot launch any other version (tried back as far as 1.4.7), including old snapshots, using the Java launcher.
Since there is no native launcher for Linux yet, that leaves Linux users unable to play the stable versions at all.
Since there is no native launcher for Linux yet, that leaves Linux users unable to play the stable versions at all
As a workaround for Arch Linux, you can use the old launcher available in AUR as "minecraft-launcher" (instead of "minecraft"): simply type "yaourt -S minecraft-launcher".
For other distros, there probably are similar packages or maybe you could extract the launcher from the tarball in the PKGBUILD: minecraft-launcher-2.0.579.tar.gz
I have the same issues. Around 1 am CT I was playing and woke up to play around 1 pm CT and it gave me the error. I can still use snapshot but I can't use a stable version. I use the Linux version. Please fix.
Same issues, I guess we need to download OpenJDK 9 now.. Because they make new features that require new jre..
@Unknown Ender: For newer versions that might be ok - but if i am using an elder one i do not think it would fix anything.
BlueSansDouze's fix works for single player, but doesn't correctly build a login token for multiplayer.
Same problem with me, looks like devs screwed linux users again... c(-_-C)
I tried updating java to java 9 and reinstalling, but now it doesn't even show launcher error log, MC screen just disappears...
This is a new issue, too
Same problem here. I'm on windows xp and gives me the error like above. Like everyone else only the new snapshot works, but no sound. Worked fine this morning between 3 and 5.
Play on 1.7.10,
Hope this gets resolved soon...
Edit: Did try deleting and reinstalling both Minecraft and java, along with deleting all Minecraft files. No luck.
Also here, Linux Mint 18 with the latest launcher (1.6.82-j) for every version of the game I tested (from 1.12.2 to 1.7.10)
I am running Ubuntu 16.04 and launcher 1.6.82-j and I am also having the same problem.
This issue is also happening for Windows players. My Windows 10 PC ran the game perfectly fine yesterday, but today it doesn't work whatsoever.
Same here. Fedora 21 x64, java-1.8.0-openjdk, launcher 1.6.82-j, Minecraft 1.12.2.
Tried reinstalling Java, deleting ~/.minecraft, downloading client.jar from mcversions – nothing worked.
This was also referenced in MC-69840
I restored .minecraft/launcher* from yesterday's backup, and started minecraft using:
java -jar .minecraft/launcher.jar
Lost my key bindings and had to log in again, but everything else is OK, and I'm connected to my server.
If you have a backup, use it.
how do you restore the files from yesterday tho? :/
also i dunno if anyone has said but
im on OSX 10.7.5
and it gives me this the same error :/
also on the old alternative launcher
I have the exact same problem. I've tried everything I could possibly thing of. The game ran fine yesterday, but not it gives the same error. I'm running Fedora 23.
Jamie, first you need to have taken a backup. Either you already did that yesterday, or you'll need some very exotic physics.
Thanks Brian Ronald, restored the launcher files from yesterdays backup and I can play again!!
If you didn't back up you're SOL until mojang fixes this 😞
Hmm...as I do not have a backup, may anyone please share their backups?
I don't believe one needs to tweak launcher_profiles.json, so please omit that.
Supposedly this launcher is no longer updated... so why is there suddenly an update which breaks everything? -an affected user
FTTB I am using MultiMC to launch the game.
Didn't have backup either. Used the latest snapshot 17w43a and it works. Could be risky of course with 1.13 features but at least I can play.
Sadly same here! Window XP, Java version 1.6.82, Worked great last night, came to use it tonight and nothing, tried restarting the computer, downloading the newest java, uninstalling and reinstalling the game and nothing, hope they fix it soon!
Please keep in mind that this site is not a discussion forum. If you would like to discuss, please go over to the Mojira subreddit. Thanks.
confirm: within the past 18 hours, and no changes to my clients, Minecraft 1.12.2 no longer launches with Ubuntu 14.04 (32 bit), Ubuntu 16.04 (32 bit), or Ubuntu 17.04 (64 bit). these are three separate machines that were all working yesterday. the error is exactly as described in this bug report for all three machines.
Ubuntu 14.04 also does not launch the latest snapshot 17w43a, though it gives different error. the error is "Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to locate library: liblwjgl32.so"
note that the minecraft launcher for my windows 8 laptop does continue to work as expected.
I'm impacted on this too; Ubuntu 17.04. As with others, using the nightly build solves the problem but there is no sound.
Still unable to play, may as well add myself to the list:
Linux Mint 18.2
Minecraft Launcher 1.6.82-j
OpenJDK 8
Can not launch any modded or vanilla profile except for the most recent 17W43 snapshot, with no sound.
Still trying to understand how they can fix the windows 10 version in under half an hour, while the rest of us are still wondering 12 hours later now.
[media]
Same issue here, two computers with Ububtu 17.10 running Minecraft 1.12.2 stopped working this evening with the same error.
same issues here , can run latest dev snapshot but no sound, and wont run 1.12.2
openSUSE tumbleweed 20171022
kernel ver 4.13.8-1-default
8 x Intel Xeon cpu E5440 @ 2.83GHz
23.5 GiB ram
I am having the same issue, I played just yesterday, powered off my computer, then the next day, turned it back on, and I now get this error even after purging my computer of both Minecraft and Java completely and then reinstalling.
Fedora 26 64-bit
Java versions:
Oracle 1.8.0_151
Oracle 1.9 (don't call specific revision)
Openjdk 1.8.0_144
I will try and test other java versions as well.
EDIT: As many others have stated, I can also run the latest snapshot.
What I can't run, is literally any version prior to this snapshot, including 1.12.2 and 1.7.10 which was the version I had been using recently.
Has anyone tried older java versions like 7 or earlier revisions of 8? This must either be a patch that was made through all the newer java versions or perhaps a change in many of the older minecraft versions (I doubt the second).
Same here. Played it last night, came home from work today, and got the error message everyone else is getting, "Could not find or load main class net.minecraft.client.main.Main"
Antergos Linux release 17.7
ARCH Linux 4.13.8-1
Minecraft Launcher 1.6.82-j
OpenJDK 8
Same issue here on Ubuntu 17.10 and both Oracle & Open JDK 8. Only version that will launch is latest snapshot.
Problem is definitively in the Java based Minecraft launcher. When I use a third party launcher like Technic 1.12.2 starts with no major problem.
Same, although the latest snapshot won't work either. Running on Ubuntu 16.04 with OpenJDK 8.0, just tried installing Oracle Java 9.0.1 and it did not solve the problem. Deleted the entire .minecraft folder and started over. No luck = I'm stuck.
There is a related issue that was resolved where the wrong version of the .jar file for an earlier MC version was being downloaded. Supposedly easy to fix and it's done (at least that's how I interpret what was listed on that bug report). I know I did not update anything on my system today, and I was playing last night, so it was downloaded today by the launcher.
back again.
After reading all comments i used a 3rd party launcher and MC is working. Technic is working w/o any problems, also the MultiMC 5.
Damn to all updates, i'll never change a running system. 😉
Same here, worked last night, not today. Been trying to figure out what happened.
Ubuntu 16.04 LTS 64-bit
Can confirm that MultiMC 5 works. Used it for the first time today, glad I did. I can play again 🙂
Was testing a bit and also started an system which i did not use for a longer time to play Minecraft. The 1.6.73-j launcher works fine under Mint 18.1 (Oracle Java 1.8.0_121-b13) and also on my main system RHEL6 (openjdk 1.8.0_141-b16).
The 1.6.82-j launcher on the other hand is not working on both systems and every start attempt is always ending in
Error: Could not find or load main class net.minecraft.client.main.Main
And other launchers i tested like the FTBLauncher are working fine.
Same here, Unbtu16.04 LTS 64 bits - 1.6.82-j launcher, tried to reinstall from Minecraft from scratch, change java version, etc.... Nothing works.
It appears to be resolved for me too, though it seems to be ignoring the Resolution setting in the launcher profiles (I have mine set to 1824 by 1026 for recording purposes as, until 1.13 at least, maybe, OBS does not play well with Minecraft's fullscreen mode).
Also fixed for me. I had to delete my forge and liteloader installs and re-install them after re-running 1.8.9, now everything is working! Maybe their aws servers were down for a bit or something?
"wait for 12 hours" while Mojang – i mean, Microsoft – quietly fixes whatever it was they broke in their launcher without a single peep to acknowledge the problem, is not an acceptable solution. but with teh shift towards removing resources from Java Edition, and pumping up their console and Pocket Edition efforts as well as monetizing plushies and whatnot, i think this will only get worse.
I'm using MultiMC (open source launcher) now, and i dont care if the Mojang launcher is fixed or not.
MultiMC SO MUCH better, all around. faster. configurable, it manages all your forge versions and mods in a way that makes sense. I can't believe i didnt know about this til now. Goodbye crappy Mojang launcher.
Just got up. Linux is showing new launcher version 1.6.84-j, instead of the broken 1.6.82-j. Least it's fixed, but i can agree with Rob Johnson's post on MultiMC. I am astounded i hadn't heard of it sooner, though it lacks a few basic options IMO.
10:15 UTC today.
Update to 1.6.84-j launcher fixes problem in Linux Mint 17.3. Vanilla and Optifine versions both run successfully.
Using Windows 1.6.84 launcher update through CrossOver runs Vanilla too. (Haven't tried Optifine with that one.)
Relates to MCL-8361
HELP! It is still having the same error for me, its not fixed. It says
Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Unrecognized VM option 'CMSIncrementalMode'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I am on Linux 16.04
I am using java 9
When I try java 8, laucnher le=aunches MC but MC never appears...
I have tried to reinstall minecraft, but no luck
This sucks
@unknown This is MCL-8255.
Launcher 1.6.84-j launches unmodified game, but still fails to launch liteloader-modified. Error is still:
OpenJDK 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
Error: Could not find or load main class net.minecraft.launchwrapper.Launch
When removing -XX:+CMSIncrementalMode and -XX:+UseConcMarkSweepGC, the error doesn't happen but the game still doesn't launch, BUT when removing -XX:+UseAdaptiveSizePolicy as well, (basically remove all arguments other than ram allocation arguments) Minecraft launches without a problem! Not a permanent solution, but a temporary one, and it may affect performance as I'm sure these arguments are important.
EDIT: It seemed to launch fine once, but then afterwards started giving me the same error..

I was able to fix the problem in Ubuntu 16.04 LTS by telling Minecraft to use a different directory. Instead of /home/user/.minecraft/, I got it to use /home/user/Minecraft/Client/
You can read how to do this here:[http://hopper.minecraft.net/help/special-characters/|link]
-EDIT: To be clear, in the /home/user/Minecraft/Client folder I created a Start.sh file that contains "java -jar Minecraft.jar --workDir /home/user/Minecraft/Client"-
I used chmod +x to make it executable.
The "." in the folder path (".minecraft") might be the culprit. Wonder if doing something similar in Windows will help to fix the problem? Can anyone else try? Confirm that using a file path without a ".minecraft" makes the problem go away?
I believe I got an update to the launcher, the issue seems to have vanished completely for all minecraft versions (tested 1.7.10 through the latest post-1.12.2 snapshots) Can anyone else confirm?
Following up on response above, it seems as though an updated launcher fixes the problem:

I tried Minecraft 1.12.2 in Ubuntu 16.04 LTS.
I've tested the following on Ubuntu 16.04 LTS, java 1.8.0-131.
Launches into the games main menu to create or join multiplayer (no extensive game testing) for Minecraft 1.12.2, 1.12.1, 1.12.0, 1.11.2, 1.11.1 and 1.7.2.
At this point I'm not getting the error:
Error: Could not find or load main classEarlier, I did get that error when I specified any arguments beyond -Xmx8G, i.e. all any one of these caused the error: -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M
New launcher 1.6.84-j allows the game to run. However, this new launcher is not setting the profile resolution. -new bug
Edit: Can anyone please Confirm This
I am using windows vista 32bit and launcher 1.6.84
start unmodded 1.8.9 works without error
1.8.9 with forge loads now without error
1.8.9 with forge and mods is loading without error
It seem to be fixed in my case now
Hi there,
XP, 32-bit, new Launcher (1.6.84-j) all MCJE Versions running.
The Truth is out there 😉
Got exactly the same message.
Using Debian, java 1.9.
Got minecraft launched with java 1.9 by removing
"-XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode"
from the JVM Arguments in the Profile Editor.
Launched with java 1.9 but not running well.
Hoped the latest release of java might have helped. Did not at all. At the contrary.
Now starting Minecraft with java 1.8 and everything works fine again.
@@unknown Thanks for pointing this out. I've not been able to reproduce this error changing JVM arguments using java version "1.8.0_151" since the launcher update.
Solved in latest launcher, 1.6.84-j for me as well (running windows 7).
Mostly solved in the latest launcher, 1.6.84-j for me, on Windows 7. Some non-vanilla versions that used to work fine still break with the error as described in this issue. In my case OptiFine 1.8.9 HD U I3, doesn't work, while OptiFine 1.12.2 HD U C6 works. Other 1.12 and 1.12.2 modded clients work fine for me as well. Not entirely resolved.
Looks like OptiFine 1.8.9 HD U H7 works fine. Other 1.8.9 versions not working may or may not be something on my end, I'm not sure, and at this point, I don't care to know anymore. I just want to play this block game.
It is still not working for me. I am on Xubuntu 17.10 64-bit. I would really like to play Minecraft again, I admin my own server. This bug is a bit of an issue for all of us. Anyone else here on Xubuntu?
Raported to work:
Os: Gentoo Linux AMD64
Launcher: 1.6.84-j
Java: Oracle JDK 1.8.0.152 [oracle-jdk-bin-1.8]
Works on Jetson TX1 Ubuntu 16.04.
openjdk version "1.8.0_131"
Launcher: 1.6.84-j
Minecraft 1.22.2
This is quite delayed, but this has been fixed now with the release of the new launcher.
As long as the launcher is allowed to fetch updates, it should run now.
I downloaded the launcher from the minecraft website directly (1.6.89-j), currently on Linux Ubuntu 18.04, Oracle Java 10.0.1:
I'm able to login
When I click Play all the content is downloaded
I does not work, these are the logs:

I already tried the following:
Edit Profile -> Enable experimental development versions.
IT didn't work.
I had identified that the error can also be caused due to two DEPRECIATED OPTIONS in JVM Arguments for launching the game!
A possible fix including enabling experimental development versions, is to remove these options in the arguments of JVM: "+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:", I had detected the error because of a warning that was shown at the Game Output telling that the JVM couldn't be started as result of the depreciated option.
I believe the java CMS warning on startup is a red herring. It issues this warning even when it runs normally. The warning is a warning, not an error. It says CMS is deprecated and may be removed in future. For now, this flag still works.
I get this same error when offline and attempting to Play Offline

I also tried running apt-get update and upgrade, to update my java version, but it did not help!
