Failed to launch debuggee in integratedTerminal. Reason: com.sun.jdi.connect.TransportTimeoutException

[hellotheresoria]

I've been trying to run the Java debugger in my windows machine using WSL but have never been able to using the integratedTerminal. Is this something that's expected? Am I only able to use internalConsole?

It works for me to run with integrated terminal in WSL. Looks like it uses wrong rule & to concate the command lines in terminal. Did you try the latest VS Code version?

I tried updating my vs code version & am now on 1.76.2 but am still seeing the same error.

Hi miguel (@hellotheresoria), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggestions:

• Use the debug console instead of the integrated terminal when on Windows + WSL. In your launch.json add:

  "console": "internalConsole"

  or set in your VS Code settings:

  "java.debug.settings.console": "internalConsole"

  This avoids passing Windows paths to a Bash shell.

• If you need an interactive terminal in WSL, open your project in a Remote – WSL window (install the Remote – WSL extension). That way the debuggee will launch natively in WSL.
