"Guessing" a class name

In Intellij (2017 at least), if there are two classes with the same name, and I remote debug a project that calls one of them – I get a message saying there is an alternative source.

With this command:

·         this.getClass().getProtectionDomain().getCodeSource().getLocation()

I can see the name of the jar file. Can't intellij "somehow" guess the project name by the class file?

I use ANT through intellij – and it's possible with MVN or Gradle as well.
