Duplicate src classpathentry in reactor mode when project depends on multiple artifacts produced by a single project

For the given multi module project:
project

• pom.xml has modules: sub1 and sub2
• sub1/
• pom.xml
• target/
• sub1-1.0.jar
• sub1-1.0-alt.jar
• sub2/
• pom.xml
• depends on: sub1-1.0.jar and sub1-1.0-alt.jar

When running "mvn eclipse:eclipse" at the root of project/, in sub2/.classpath, the classpathentry for sub1 will be generated for each artifact produced by sub1 that sub2 depends on:
<classpath>
<classpathentry kind="src" path="/sub1"/>
<classpathentry kind="src" path="/sub1"/>
</classpath>

Eclipse therefore complains about a duplicate classpathentry.

A workaround is to manually remove the duplicate project from the Java Build Path.

Kind regards,
