Build and debug a single Java package with "Debugger for Java" VS Code extension

I need to configure a VS Code debugger in such a way so that it could build and run only specific packages from my Java project without even touching the others.

The problem is that I have a huge project that consists of a number of completely unrelated packages with half of them throwing compile-time errors.

Example project structure

• Project
  • src
    • crappy_package
      • broken_file.java (x100500)
        • package src.crappy_package;
    • good_package
      • healthy_file.java (x100500)
        • package src.good_package;
