I’m getting a weird problem when I try to import sources/docs with an IntelliJ pants project. Specifically, an `Exception caught: (pants.backend.jvm.ivy_utils.IvyResolveMappingError)`:

Exception caught: (pants.backend.jvm.ivy_utils.IvyResolveMappingError)

Exception message: Already defined module IvyModuleRef(net.sourceforge.f2j:arpack_combined_all:latest.integration:javadoc:jar), as rev 0.1!

The command line being executed is:

pants --target-spec-file=/private/var/folders/zn/04ckg50s6c70p76y0s564r7c0000gn/T/pants_target_specs7.in --no-quiet export --output-file=/private/var/folders/zn/04ckg50s6c70p76y0s564r7c0000gn/T/pants_depmap_run1245.out --formatted --export-libraries-sources --export-libraries-javadocs

Running this command on the command-line triggers the same error, so it doesn’t seem like it’s IntelliJ/IntelliJ-pants related, but it’s definitely because I’m exporting sources/javadocs. Is this a problem somewhere in my deps?

Cc @wide-energy-11069. Any idea what’s going on?

unclear, haven’t touched ivy for a while. but seems like a legit error from ivy, possibly conflicting versions of the same library?
