A maven plugin to find and flag duplicate classes and resources on the java classpath.
This ensures stability and reproducability of a maven build and will flag possible problems or conflicts with dependencies in a project.
This plugin is a friendly fork (same main authors) of the Ning maven-duplicate-finder plugin. It is configuration compatible to the ning plugin; the only change required is the group and artifact id of the plugin itself.
The plugins requires Apache Maven 3.x.x.
Starting with release 1.2.0, Java 7 or better is required.
Starting with release 1.3.0, Java 8 or better is required.
Starting with release 1.5.0, Java 8 or better is required to run the plugin and Java 9 or better (Java 11 strongly recommended) is required to build the plugin.
The plugin has two goals:
duplicate-finder:check- the main goal of the plugin. Runs duplicate check on the maven classpaths.duplicate-finder:help- displays standard maven plugin help information.
Up-to-date documentation is available from the duplicate finder plugin Wiki. A snapshot from the last release of the plugin is available in the docs folder in this repository.
