Tobias Oberlies created MDEP-449:
------------------------------------
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
{noformat}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>

<type>zip</type>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>

{noformat}
the log output is the following:

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:
