-
[~rfscholte] Thanks for the quick response. Let me have one more attempt at
explaining (more concisely) what I consider the bug to be, and I will close
this ticket if this is considered desired behavior.
I have a project with a declared dependency on g: com.acme a: foo v:
1.2.3-SNAPSHOT. I am using the maven dependency plugin to resolve these
dependencies. I have not specified the dependency type so I guess I assumed it
defaulted to "jar".
I am using artifactory and snapshots are stored with timestamps.
Latest deployed snapshot of com.acme:foo:1.2.3-SNAPSHOT has a pom.xml with pom
packaging. There are no deployed jar files for this snapshot.
Expected behavior: Compiling my project that depends on this artifact now fails
with "dependency has no jar" or just fails to resolve the classes.
Actual behavior: The maven dependency plugin ignores the latest snapshot and
looks for an older snapshot that did have a jar file deployed, despite me using
`-U` to force the latest snapshot to be used.

> Project: Maven
> Issue Type: Bug
> Components: Dependencies
>Affects Versions: 3.5.0
>Reporter: Andy Grove
>Priority: Major
>
> I have two projects, A and B.
> A started out as a simple project with single pom with jar packaging.
> B had a dependency on A.
> A was refactored to be multi module where each module has jar packaging. The
> parent pom now has pom packaging.
> After building A and deploying new artifacts to artifactory, and making
> changes to B's pom I saw compilation errors with references to to the old A
> and the new A.
> I eventually realized that B still had a reference to the original artifact
> from A (which was originally had jar packaging but now has pom packaging).
> Even though the latest snapshot for the parent pom in A was correctly
> published with pom packaging and no corresponding jar file, the
> maven-dependency-plugin was resolving the jar file from the previous snapshot
> release from before the refactor.
> This seems like a bug to me. It should have looked at the pom for the latest
> snapshot and seen that it had pom packaging and then failed to resolve the
> jar.
