I put in <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <configuration> <workspace>${basedir}</workspace> </configuration> </plugin> </plugins> on my pom.xml which is located in the root of my workspace directory. I have submodules defined as well <modules> <module>archetype-web</module> <module>archetype-domain</module> </modules> When I execute (while RAD 6.0 was not running) mvn eclipse:add-maven-repo The file in .metadata does not get updated and does not appear in the classpath variables Also, it creates two sub directories archetype-webX and archetype-domainX which contain org.eclipse.jdt.core.prefs org.eclipse.jdt.core.classpathVariable.MAVEN_REPO=H:\trajano\.m2\repository So even if the path is correct, the variable name isn't even correct. It should've been M2_REPO
