Rebuilding m2e discovery catalog
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,
- m2e 1.0.x http://download.eclipse.org/technology/m2e/discovery/directory.xml
- m2e 1.1.x http://download.eclipse.org/technology/m2e/discovery/directory-1.1.xml
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.
m2e discovery catalog
As of version 1.0.0 m2e discovery catalog content is hosted at https://repository.sonatype.org/content/repositories/forge-sites/m2e-discovery-catalog/. This repository is generated by m2e discovery catalog publishing job https://builds.sonatype.org/view/m2eclipse/job/m2eclipse-catalog/ and contains
- catalog entry jar referenced from discovery.xml
- p2 repository that includes catalog items retrieved from Maven repositories
The job execution has to be triggered manually and requires access to Sonatype build infrastructure.
