This is a known issue redhat-developer/vscode-java#1086, which is already fixed in the Language Support for Java(TM) by Red Hat extension 0.51.0 release.

Could you update the Java extension to latest version and try again?

I am having the same problem, and I also have the v0.51.0 version. I don't know how to do this command F1 -> Java: clean the Java language server workspace could you elaborate?

@wiazur Try the following steps:

1. Open VS Code Command Palette... via shortcut key F1 (or Ctrl + Shift + P)
2. Execute command Java: clean the Java language server workspace

I am facing this problem.

I can build .war file with maven and run it successfully.
I can also debug the project in IntelliJ.

But in VSCode, I get NoClassDefFoundError.
I have tried the fixes mentioned above, but they did not help.
