FileSystemException for java project in wsl

SonarQube for IDE IntelliJ Platform
1

Please provide

  • Operating system: Microsoft Windows 11 Pro 10.0.22631
  • SonarQube for IntelliJ plugin version: 11.6.0.83783
  • IntelliJ version: 2025.2
  • Programming language you’re coding in: java
  • Is connected mode used:
    • SonarQube Cloud, SonarQube Server, or SonarQube Community Build? (if one of the latter two, which version?): SonarQube Server v9.9.6

And a thorough description of the problem / question:

With intellij on windows i open a java project in the wsl, using a jdk also in the wsl.

The connection to the sonar qube server is working, since i got notifications of quality gate failure.

There is an error when running the analysis (regardless of the file being analyzed). The log is:

Hello @giorgioscat

Can you please provide more details on your project setup? How your JDK is installed via IntelliJ or it was installed separately and provided, do you have some non-default settings like sonarlint.jre.path. Maybe something else unusual about your project?
I have tried to reproduce the problem - I couldn’t.

Also I can see that you provided only part of the logs. Do you feel comfortable to share the full log of the session? Obviously it’s OK to remove all the sensitive data like project name, user name and so on.

Kirill_Knize, sorry for the late reply (i got no email notification for your comment).
The jdk was installed separately and provided, running java -version (in the wsl) it prints:

openjdk version "1.8.0_472"
OpenJDK Runtime Environment (build 1.8.0_472-8u472-ga-1~25.04-b08)
OpenJDK 64-Bit Server VM (build 25.472-b08, mixed mode)

I have no non-default settings.

The following is the entire log i get when clicking “Analyze current file” (with some information redacted):
