purging local repository leades to invalid repository meta data

After using the dependency:purge-local-repository goal, purged artifacts are no longer downloaded from repository manager.

To reproduce do the following:

• extract the attached multi-module project. It consists of a parent, artifact1 and artifac2. artifact1 has a dependency to artifact2.
• adapt the <distributionManagement> so you can deploy to a repository manager
• cd demo
• mvn deploy
• cd artifact1/
• mvn maven-dependency-plugin:purge-local-repository -DreResolve=false
• mvn validate

The result of the last "mvn validate" is like this:
