             Summary: unpack fails to download SNAPSHOT artifact with classifier
                 Key: MDEP-449
                 URL: https://jira.codehaus.org/browse/MDEP-449
             Project: Maven Dependency Plugin
          Issue Type: Bug
    Affects Versions: 2.8, 2.7
            Reporter: Tobias Oberlies


The unpack goal fails to replace the literal {{SNAPSHOT}} in the URL when trying to download snapshot artifacts with a classifier.

For this configuration

            </artifactItems>
         </configuration>
      </execution>
   </executions>
</plugin>

the log output is the following:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:unpack (default) on project dependency-copy-test: Unable to find artifact.

{noformat}

The problem is that the {{SNAPSHOT}} in the download URL is not replaced by the qualifier used in the remote repository.

For comparison, this is the log output for an artifact without classifier:
