One of my dependencies doesn't seem to be resolved properly (tu17

I have a configuration called jres.

In the dependencies section, I have:

jres group: 'jre', name: 'jre', version: '7u60', classifier: 'solaris64', ext: 'tar.gz'
    jres group: 'jre', name: 'jre', version: '7u17', classifier: 'linux-x64', ext: 'tar.gz'
    jres group: 'jre', name: 'jre', version: '7u17', classifier: 'windows-x64', ext: 'tar.gz'

I have a downloadDependencies task that does this:

configurations.jres.resolvedConfiguration.resolvedArtifacts.each { artifact ->
        project.copy {
            from artifact.file
            into "build/jres"
          }
    }

But when building, I get this weird error:

:upgrader:downloadDependencies FAILED
  FAILURE: Build failed with an exception.
  * Where:
Build file 'C:\xxxx\build.gradle' line: 57
  * What went wrong:
Execution failed for task ':upgrader:downloadDependencies'.
> Artifact 'jre:jre:7u60:jre-linux-x64.tar.gz' not found.

Why is the artifact resolver try to download ‘jre:jre:7u60:jre-linux-x64.tar.gz’ ? This does not seem to be an artfact that I declared in my dependencies. I didn’t have the problem until I added the solaris jre as a dependency (and then, the two dependencies were having the same version (7u17). I only introduced a new version (7u60) with the new dependency and now this prevents the previous dependencies to be found because they are looked for with the incorrect version.

Am I missing something? Is there any way to work around this without me having to rename my artifacts or change their coordinates in the repository?

Thanks in advance,

Laurent.

Doing some research, I added

resolutionStrategy.failOnVersionConflict()

in my jres cofniguration and can see that there is a conflict:

> Could not resolve all dependencies for configuration ':upgrader:jres'.
   > A conflict was found between the following modules:
      - jre:jre:7u60
      - jre:jre:7u17

I was hoping that the classifier would be enough to make the distinction between artifacts.

In the end, it does look like it’s my problem because I received a warning saying that I should not rely on the classifier name, and that this will be deprecated in 2.0. I guess I have to change the coordinates of my artifact after all. I’ll do so.
