src/test/resources/META-INF/maven/org.apache.maven/maven-core/pom.properties necessary for running junit-tests in eclipse

i'm currently fixing bugs for the eclipse-plugin ... i use eclipse for this

so i checked out the trunk, mvn install, then mvn eclipse:eclipse

i can run the test "org.apache.maven.plugin.eclipse.EclipsePluginUnitTest" only with errors.

i must create a file "src/test/resources/META-INF/maven/org.apache.maven/maven-core/pom.properties" with the content
version=2.6-SNAPSHOT
groupId=org.apache.maven.plugins
artifactId=maven-eclipse-plugin
to run this test sucessful

any ideas?
