vscode-java: Does not resolve to a ICompilationUnit

RedHat Language for Java is just not working No linter, no code suggestions, no “popups” on hovering, anything

I’m able to get the following error: [Error - 21:08:10] 08-Oct-2018 21:08:10 file:///home/diego/GitHub/MAKEROID/Makeroid/appinventor/components/src/com/google/appinventor/components/runtime/util/crypt/MakeroidAES256.java does not resolve to a ICompilationUnit

Make sure to have a org.eclipse.jdt.core.javanature in your .project file.

I had the same issue with Apache flink -mvn eclipse:eclipse did the trick. This also generates the .classpath.

Try deleting vscode-java’s working directory and restart VS Code (Next version will provide a command to do it directly from VS Code)

I am still getting this issue even after performing the clean java workspace command in VS Code.

I started seeing the same issue recently as well. Cleaning java language server workspace does not fix for me. However, running mvn eclipse:eclipse resolves the problem and that does seem to work for me.

But I don’t believe that should actually be required and is kind of a pain to figure it out…

Looks like an Android application. FYI vscode-java doesn’t support Android project development.
