Hey and thanks for reporting! So for starters the java-language-server unfortunately requires Bash to be installed, even on Windows. It seems like you have Bash installed so that's not the issue. The error output suggests something else is going wrong with path separators being removed (.scriptslink_windows.sh should be ./scripts/link_windows.sh).

I have an idea of what could be wrong, I'll have to test some further the next time I'm on a Windows machine.

The JAVA_HOME environment variable is not defined correctly Have you set the variable in your environment? I recommend using :MasonInstall java-language-server@v0.2.32 from the reference https://github.com/georgewfraser/java-language-server/issues/255

I had the same issue and installing maven with scoop fixed it for me, even with the path separator issue in the link_windows.sh script.
