@maxtarquini could you attach a project example reproducing the error?

[maxtarquini]

@snjeza every maven project.
Everything where working until 2 days ago and now all vscode stopped working with all java project.
attached a simple maven project i did for some students.
esempi.zip

[maxtarquini]

Some more informations. running tasks: configure vscode prompt for input but nothing else happen. Disabling java language support by red hat the problem is fixed but vscode is not usefull anymore :(

[snjeza]

@maxtarquini Could you try the following:

• close VS Code

$ rm -rf ~/.vscode/extensions/redhat.java* # remove VS Code extension

• start VS Code and reinstall Language Support for Java(TM) by Red Hat

[maxtarquini]

@snjeza did it and nothing change. I did many many tests:
removed vscode, .vscode and .config/Code folders and intalled an older version (1.71) for vs code. Nothing changed
removed .vscode and .config/Code folder, installed java extensions pack and downgraded to older version. Nothing changed
vscode update to last version using older version for language pack. Nothing changed

May be the rpm installer install something somewhere i don't know?
Once i cleaned .vscode folder and .config/Code folder did i removed everything?
Is there some king of cache?

[maxtarquini]

@snjeza some more info. If i ask for build status i got this:

Error: there is no registered task type 'Java'. Did you miss installing an extension that provides a corresponding task provider?
Error: there is no registered task type 'Java'. Did you miss installing an extension that provides a corresponding task provider?

The problem seems to appear when language support try to build the workspace.

[maxtarquini]

@snjeza i'm available for a remote session if you desire.

[snjeza]

@maxtarquini could you run

$ ls ~/.vscode/extensions

[maxtarquini]

@snjeza
╰─$ ls ~/.vscode/extensions
redhat.java-1.11.0-linux-x64 vscjava.vscode-java-dependency-0.20.0

[maxtarquini]

@snjeza if is use ctrl+shiftp+p task: rerun last task result is still the same

Error: there is no registered task type 'Java'. Did you miss installing an extension that provides a corresponding task provider?

When i manually use task: run build task vscode shows the messages in the picture

[snjeza]

@maxtarquini could you try

• close VS Code

 $ rm -rf ~/.config/Code/User/globalStorage/redhat.java/

• start VS Code

[maxtarquini]

@snjeza nothing changed :(

[maxtarquini]

@snjeza i created another user, logged in, executed vscode and created java project.
Everything works well. May be there is something that may affect vscode within user folder?

[snjeza]

@maxtarquini you can try to remove the ~/.config/Code and ~/.vscode folders and restart VS Code

[maxtarquini]

@snjeza as you can read in the previous comment i did it tens of times and nothing change. I'm now moving my productivity to a new user (vscode works as exepected). Will leave old user active for further investigations. My idea is to start cleaning user folder step by step until i find where the problem is.

[maxtarquini]

Hello @snjeza as a good noews i found the reason why the extension was blocked. It depends by a environment file. I need to understand which env variable is creating the problem but seems that i definitively fixed.
I can consider this issue closed.

[pouriamoosavi]

I have the same issue.
If you found the fix would you please share it here?

Turns out our issue was related to windows region/region format setting. It seems that this extension has some issues with Persian/Arabic region formats.

Can anybody please explain why this happens?

Is the problem with java runtime configure?
