Migrating Nexus plugins from Plexus to JSR-330

In Nexus 2.7 we culled from Nexus source almost all use of Plexus based components to complete the migration to using JSR-330 Eclipse Sisu instead. Any remaining usage is deprecated.

Warnings will be logged on startup when Plexus components are detected in your custom Nexus plugins.

All third party plugin developers should migrate components to ensure their plugin will work with newer versions of Nexus.

Detailed instructions for migrating your plugin are available.


Sample WARN messages you may see on startup of Nexus. These WARN messages can be safely ignored, unless the classes mentioned are in a custom plugin not distributed from Sonatype. In that case, contact the plugin author and encourage them to update their plugin.
