Hello.

coc-java worked fine for me, but recently it stopped working for some reason - it fails at the startup.

(I'll be happy to provide further info if needed)

Same problem here !

[eliasdaler]

Reinstalling coc-java has helped for me (CocUninstall coc-java + CocInstall coc-java.

I also cleaned various caches (:CocCommand java.clean.workspace + :CocCommand java.clean.sharedIndexes).

Try this.

[danickblouin]

@eliasdaler I did rm -r .config/coc/extensions/coc-java-data/* and it also fixed the problem for me, but I already did that last week and the problem came back. (I'm using neovim I don't know if it's in the same path for Vim) Let's hope it doesn't happen again 🤞

[eliasdaler]

Yep, it literally happened to me again right now... :CocCommand java.clean.workspace helps, but calling it again and again isn't really pleasant.

this works for me

It worked for me at first but just like I said, the problem came back after some time... Let us know if it does the same thing for u

[Taz03]

it happens everytime i close and reopen (neo)vim

it came back like you said. it worked fine up until today since the last time i temporarily fixed it.

[Taz03]

i just do :CocCommand java.clean.workspace and it fixes it for me, it isn't much work but would be great if this gets fixed

[Natan-P]

can confirm this is still an issue i'm pretty certain that the issue is that the language server isn't done in 5 seconds, which for me is almost every time, since i'm running an i3-2100 i wonder though, why does it not do that on java.clean.workspace? i'm guessing there's a flag passed to alert that something is in progress... if i find some time, i'll dig into the source code and see what could be done

[halarus]

Can confirm, just happened to me. Any updates on this?

[chemzqm]

Seems the server crashed for some unknown reason, need check the server log
