#20794 jvm_exclude with Group Only Fails Parsing by Coursier Issue created by NGustafson Describe the bug Running

pants generate-lockfiles

when a

jvm_artifact

contains a

jvm_exclude

that only specifies a group will fail with a "Failed to parse [group-name]" message from Coursier. This is contrary to the documentation for

jvm_exclude

which states "`jvm_exclude`: Exclude the given

artifact

and

group

, or all artifacts from the given

group

." Pants version 2.20.0rc2 OS MacOS Additional info Example Repo https://github.com/NGustafson/pants-examples/blob/main/3rdparty/jvm/BUILD This repo has a single jvm_artifact with nothing else configured. Attempting to run

pants generate-lockfiles

will cause this error:
