Maven plugin to find duplicate classes or resources

chinnu

duplicate-finder Maven plugin

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.

About

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.

Requirements

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.

Goals

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.

Documentation

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.

Release Notes

1.4.0

added

changed

• Build with basepom 30
• use slf4j 1.7.28 (from 1.7.21)
• update plugin plugin to 3.6.0 (from 3.4)
• update groovy to 3.0.0-beta-3 (from 2.4.12)
• changed Travis Build to use OpenJDK 8 and 11
• Clarify much more what is a resource and what is considered a class. This changes a lot of things that used to be matched as classes to be matched as resources. Especially all path elements (directories, jar file folders etc.) now must match the Java identifier specification. This e.g. rejects classes in Multi-release jars that are located in META-INF/versions/<version> because META-INF or the version number are not valid Java identifiers. An exception is made for package-info and module-info class files, whose names are not valid Java identifiers but are still loaded as classes from the class path.
