Need some help with check goal, with Javac with depends on a proto goal. 🫶 Then it complains about a python requirement within jvm context. I am pretty confused what is going on here

pants check --only=javac  src/java:: src/jvm::
14:37:46.29 [ERROR] 1 Exception encountered:

Engine traceback:
  in `check` goal

ClasspathSourceMissing: No JVM classpath providers (from: CompileJavaSourceRequest, CoursierFetchRequest, DeployJarClasspathEntryRequest, JvmResourcesRequest) were compatible with the combination of inputs:
  * 3rdparty/python:delta-spark#protobuf	(python_requirement)

Where my proto build file is like

protobuf==3.20.1

Hmm, is the python protobuf backend enabled in this repo?

Yes

So this is a bad interaction between the two protobuf backends, I guess during dep inference (when Pants looks at the entire repo)

Sure let me find out how to create a smaller reproducible code :)

I reproduce locally with that repo, thanks

Thank you!
