Not sure if it's a bug or not.... In jvm you need to use

jvm_artifact.excludes

heavily to fix transitive dependencies conflicts. That brings the idea of grouping several jvm_artifacts together to form

working groups

(groups of artifacts that 100% have no conflicts and can work nicely together) Based on pants documentation here - "*target* ...This can be used as a generic "bag of dependencies", i.e. you can group several different targets into one single target so that your other targets only need to depend on one thing...." But if I try to include empty target in the dependencies of

scala_library

I get this:

ClasspathSourceMissing: No JVM classpath providers (from: CompileScalaSourceRequest, CoursierFetchRequest, DeployJarClasspathEntryRequest, JvmResourcesRequest) were compatible with the combination of inputs:
  * src/main/scala/com/testingzone/test:test    (target)

Should this be logged as issue? Or there is a better way of grouping scala/java dependencies and then using them? P.S: As a temporary workaround I created folder with empty package object

depends/package.scala

and defined dependencies like this:

scala_sources(
    name = "fs2",
    sources = ["package.scala"],
    dependencies = [
        "3rdparty/jvm/co/fs2:fs2-core",
        "3rdparty/jvm/co/fs2:fs2-io",
    ]
)
