Rebuilding m2e discovery catalog
As of version 1.0.0 m2e discovery catalog URL is http://download.eclipse.org/technology/m2e/discovery/directory.xml. It is hardcoded in org.eclipse.m2e.internal.discovery.MavenDiscovery.PATH found in o.e.m2e.discovery bundle. discovery.xml can be changed from dev.eclipse.org or build.eclipse.org as ~/downloads/technology/m2e/discovery/directory.xml. It is not necessary to change discovery.xml unless you want to relocate or block catalog.
