Hello Team,

I use devstyle and really appreciate this eclipse plugin.

But recently I decided to migrate to 06-2020 and have issues wherein I am not able to use my workspace more than once.

I use the latest version of eclipse + devstyle + codemix, when I setup my workspace everything works fine. But then if I restart then its a mess and I cannot start. The only way to bring up the workspace is to use “-clean -clearPersisted” when starting eclipse or recreate workspace. But both are not acceptable.

I looked into the logs and observed the following in the logs which made me think to post it here (just in case you can help):

Thanks in advance for any pointers.

Using windows10 (devstyle theme + intellij dark theme)

Thanks!

Ankur, thanks for reaching out!

I don’t see anything that can break your workspace initialization in those logs (not even that NPE in LanguagesService). Can you try running eclipse with eclipse.exe -console -consolelog and see if there’s an interesting error displayed in the output?

Cheers!

Thanks for the quick reply. I understand that those might not be the reason of the failure but I only see them. I will add the mentioned flags and will update you when this happens. As I mentioned to recovered I used clean flags to move ahead.

Maybe this is the cause but not sure where this is arising from:

Hi,

Thank you for sharing the stacktrace. I am afraid the above stacktrace is not the cause for the problem you are seeing.
Please send us elaborate logs to help us investigate further.

1. Please run Eclipse from command line with : eclipse.exe -console -consolelog as suggested by Aaron, select a fresh workspace and replicate the issue.
2. Once replicated, share with us the complete output of the command window along with the complete/full .log file located at workspace dir/.metadata/.log. For .log file, rename the extension to .txt and attach it here. If there are .bak_X.log (backup logs) in the .metadata folder, then zip all of the .bak_X.log files along with the .log file and attach it here.

Apologies for inconvenience caused.
