Fails to build any project with NoClassDefFoundError

[grguthrie]

I have a new install of IntelliJ Idea 2021.1 (updated) running fine. Then I opened a .hs file and it asked for a haskell plugin - I had HaskForce (disabled) and said yes - enable and update.
Then restarting the IDE it gives this error: and the IDE cannot even start.
I had to remove the Haskforce plugin to get it to work.
Thanks for any hints.

Internal error. Please refer to https://jb.gg/ide/critical-startup-errors

I have a maybe similar issue with Pycharm 2020.3 : when installing haskforce, after restarting the IDE, it show in the plugin list as not installed.

The installation fails without a message for me.

EDIT: Nevermind, the logs tells that Haskforce is not compatible with pycharm :(

This should be fixed in the latest release - https://github.com/carymrobbins/intellij-haskforce/releases/tag/v0.3.46

Please reopen or submit a new issue if you encounter any other problems!

Thank you. I re-enabled the plugin, and actually downloaded and installed from the website. Trying to build simple .hs file I get this: Internal error (java.lang.NoClassDefFoundError): Could not initialize class org.jetbrains.jps.incremental.BuilderRegistry$Holder java.lang.NoClassDefFoundError: Could not initialize class org.jetbrains.jps.incremental.BuilderRegistry$Holder at org.jetbrains.jps.incremental.BuilderRegistry.getInstance(BuilderRegistry.java:32) at org.jetbrains.jps.cmdline.BuildRunner.runBuild(BuildRunner.java:127) at org.jetbrains.jps.cmdline.BuildSession.runBuild(BuildSession.java:301) at org.jetbrains.jps.cmdline.BuildSession.run(BuildSession.java:132) at org.jetbrains.jps.cmdline.BuildMain$MyMessageHandler.lambda$channelRead0$0(BuildMain.java:219) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834) And in fact, it breaks all other projects (.java) as well, I had to disable the plugin to get anything to build. This is on IJ 2021.1.1
