[krasa]

Seems like IntelliJ bug. You could try uninstalling the plugin. It works fine for me.

[krasa]

It reminds me https://youtrack.jetbrains.com/issue/IDEA-237519 when plugins were in a wrong location. Your IDE version?

[KarlManong]

I got the same exception

[KarlManong]

I'm using the latest stable idea ultimate and the latest plugin

[krasa]

:( I've hidden the update for now https://plugins.jetbrains.com/plugin/7179-maven-helper/versions/stable/135611

[KarlManong]

4.15.212.000.0 works well.

[krasa]

Could you paste the content from Help | About | Copy?

[hsz]

Could you please attach idea.log logs? You can upload it securely here: https://uploads.jetbrains.com and provide the generated name.

[KarlManong]

Could you paste the content from Help | About | Copy?

Manual installed with version https://plugins.jetbrains.com/plugin/7179-maven-helper/versions/stable/135611, and everything works fine. I don't know why.

Current I have no way to reproduce. Sorry for that.

[ahus1]

I've seen a similar exception with a plugin that I maintain, and with other JetBrains plugins. Please let me know I you feel offended by hijacking this. Seen with IntelliJ IDEA 2021.2.1 Build #IU-212.5080.55. / cc: @hsz

2021-08-31 22:53:34,519 [46126956]  ERROR - mpl.search.PsiSearchHelperImpl - Error during processing of: plugin.xml

I happen to have a log file. I uploaded it here: Upload id: 2021_09_06_VJBTEFWbMmimysgg (file: idea.log.1)

[annaMarchenkoJetBrains]

@ahus1 thank you very much for providing your idea.log, it helped me to reproduce the problem. I filed an issue https://youtrack.jetbrains.com/issue/IDEA-277738 You can follow the state of the ticket there.

[annaMarchenkoJetBrains]

@ahus1 please try the latest nightly https://confluence.jetbrains.com/display/IDEADEV/IDEA+2021.2+latest+builds Does it work for you? I can reproduce the same problem only on IU-212.5080.55, but not on IU-212.5284.31 I would say, the issue is fixed and will not reproduce in new builds

[ahus1]

Hi @annaMarchenkoJetBrains - I see that IU-212.5284.31 is the 2021.2.2 RC, and I'll install it.

I have never been able to reproduce the issue intentionally, I only looked at my logs now and then.

Is there anything I should try out?

[annaMarchenkoJetBrains]

@ahus1 the issue is unfortunately unstable to reproduce and I saw it already on all three builds - your current, on IU-212.5284.31 and on the most recent build which is not available for users. I will keep you posted and inform you when we fix it and the fix will be included in the future builds. Thanks

P.S. The issue happens during analysing of file when you open a file in the Editor. Probably, Android plugins should be disabled.

[krasa]

@annaMarchenkoJetBrains any workaround? Why does it happen only after a plugin update? https://github.com/krasa/FrameSwitcher/issues/35

[krasa]

Hmm, it should be fixed in 213.3565, 212.5394 - https://youtrack.jetbrains.com/issue/IDEA-277738
