       I'm just a little confused - does this actually run some Java code? I think it will run `java` and `javac`, right?

Review comment:
       oh I guess this test does not actually run it - can you add a comment about what this test checks so that it's easy to read for others? thanks!

       we need to find the class with `main` method, right? How do we do that? Will it always be the last one?

Review comment:
       I suppose this is for Java, right? or do we also expect a class name for go/python?

Review comment:
       if we generate the uuid here without inspecting the pipeline, when will we ever have a cache hit for any given pipeline? what will be the job of the cache?

Review comment:
       does it make sense to also add compiler output to cache in case of success? (maybe not - but if it doesn't, let's document)
