[INFO] Error unpacking file: c:\D\desarrollo\proyectos\plataforma\platform-core\target\classes to: c:\D\desarrollo\proyectos\plataforma\platform-bundle\platform-bundle-jar\target\classes
org.codehaus.plexus.archiver.ArchiverException: The source must not be a directory.

Project structure is as follows:

plataforma

• platform-core
• platform-bundle
• platform-bundle-jar
• platform-bundle-src

and the error happens on executing any goal from parent pom. maven-dependency-plugin seems to receive a reference to target/classes directory for platform-core dependency instead of the URL to my local repository where platform-core is located.
