Zac: Feel free to open a new topic to address your issues in building, etc. In general you'll probably want to pull down AS trunk: http://anonsvn.jboss.org/repos/jbossas/trunk/ ..then metadata: http://anonsvn.jboss.org/repos/jbossas/projects/metadata/trunk/ metadata Make your changes/tests in metadata, then: mvn clean install To integrate your new metadata SNAPSHOT with the AS build, you update in AS component-matrix/pom.xml: <version.org.jboss.metadata>1.0.0.CR16</version.org.jboss.metadata> | ...to the correct version. Then build AS: as_trunk$> cd build; ./build.sh Again, any issues, just open a new Thread and we'll walk you through anything not covered in the Wiki. Also see http://www.jboss.org/community/wiki/MavenSettings for the M2 settings you'll need to access our public repos.
