You can use the following to build & test the
target-platform locally against your component(s).

Build target-platform:
$ cd /path/to/jbosstools-target-platforms/jbosstools/multiple
$ git fetch origin pull/999/head && git checkout FETCH_HEAD
$ mvn clean install

Then, to test the new "multiple" target platform against your component's build:
$ cd /path/to/your/jbosstools-component
$ mvn clean verify -Dtpc.version=4.60.0.Alpha1-SNAPSHOT
-Dtpc.targetKind=multiple
