m2e discovery catalog URL is hardcoded in org.eclipse.m2e.internal.discovery.MavenDiscovery.PATH found in o.e.m2e.discovery bundle. To allow discovery catalog items to be compatible with some m2e versions but not all, each minor m2e version has different URL. Specifically,

discovery.xml can be changed from or as ~/downloads/technology/m2e/discovery/directory.xml. It is not necessary to change discovery.xml unless you want to relocate or block catalog.
