After update to latest version CodeMix is completely broken: An internal error occured during: „Initializing CodeMix Engine“. java.lang.NullPointerException.

Editors will hang at „About to Start“.
„Reload CodeMix Engine“ button doesn’t help, hangs at „Restarting“.

Deleting ~/.codemix doesn’t help.

Deleting ~/.codemix again and rebooting didn’t help either.

Nabil,

Sorry that you are seeing this issue. Thank you for sharing the log entries.
It looks like a permissions issue. With recent versions of CodeMix, the extensions folder is being moved to the STS/Eclipse installation directory from the .codemix folder of your user home directory. CodeMix is failing to create the extensions folder in your STS installation directory due to permissions issue.

1. Does your account have full permissions including write access to the STS installation folder? If STS is installed as root user and if you are trying to run it as non-root user, then you might face issues with the permissions. Try running STS as root user and check if it fixes the issue.

2. If you have trouble fixing the STS permissions, then you can try to change the location of the extensions directory to the location which you have permissions for. Go to Window > Preferences > CodeMix > Miscellaneous > Storage page. Uncheck the use default storage location for CodeMix Extensions and set the location to the folder where you have full permissions including write access, apply the changes and restart the IDE.

Apologies for inconvenience caused. Please let us know how you get on with it.
