             Summary: ArtifactUtils#toSnapshotVersion problem with pinned snapshots
                 Key: MNG-6735
                 URL: https://issues.apache.org/jira/browse/MNG-6735
             Project: Maven
          Issue Type: Bug
          Components: Artifacts and Repositories
    Affects Versions: 3.6.1
            Reporter: Laird Nelson


I apologize in advance for the vagueness.

In {{ArtifactUtils}}, there is a method named {{toSnapshotVersion(String)}}.

I am using a project whose released version depends on a pinned snapshot: [https://github.com/jbosstm/narayana/blob/a66d5bd3ebfa96ab7e4142f28960a99b941a30e7/rts/lra/pom.xml#L29]

This works fine for things like unit tests and so on.

For various reasons, some of which are good and some of which are bad, we need to copy this pinned snapshot using the Maven dependency plugin's {{copy-dependencies}} goal.  We construct a prefixed classpath entry in a jar file's manifest that refers to this pinned snapshot version.

When we do so, we discover that although this project depends on a pinned snapshot, and although the Maven shared archiver constructs the manifest {{Class-Path:}} entry properly, i.e. referring to the pinned version, not anything ending in {{-SNAPSHOT}}, the {{copy-dependencies}} goal seems to infer that the pinned version is in fact a snapshot version, and so when the jar file is copied it ends up with a suffix of {{-SNAPSHOT}}.  The end result is that although the {{Class-Path:}} header is correct, no such pinned snapshot version jar file exists.  Instead, a jar file with {{-SNAPSHOT}} as a suffix is there instead, and we get classloading errors.

I've traced the problem to {{ArtifactUtils}} where its {{toSnapshotVersion(String)}} method appears to recognize this pinned version string as a snapshot, and "helpfully" erases it, turning the resulting jar file back into a {{-SNAPSHOT}} suffixed jar file.

I don't see any workaround to this problem.  Is there a reason for this helpful behavior?
