This page discusses emerging ideas of "clean up" of Maven project and it's its related sub-projects.

General guidelines

...

• Make sure Plexus AbstractLogEnabled is not used (extended), Maven since 3.x uses SLF4J instead.
• Make sure ancient org.codehaus.plexus:plexus-container-default is NOT used as dependency IN ANY SCOPE. In general, all shared components should be migrated to JSR330, while use of Plexus Container MAY BE still needed in UTs (due Plexus Components present in dependencies). Then use : use Sisu Plexus Shim instead (but only in test scope) : = org.eclipse.sisu:org.eclipse.sisu.plexus (currently 0.3.5, soon 1.0.0), because in general, all shared components should be migrated to JSR330, while use of Plexus Container MAY BE still needed in UTs (due Plexus Components present in dependencies).
• Make sure components in project use JSR330 annotations and not org.codehaus.plexus:plexus-component-annotations or EVEN WORSE, the Plexus QDox Javadoc annotations.
• Drop use of Plexus Component Descriptor and org.codehaus.plexus:plexus-component-metadata plugin, and use org.eclipse.sisu:sisu-maven-plugin instead.

Maven

• ... should really drop Maven 2.x support (was it 10 years?), so maven-compat must go.
