deadcode4j helps you find code that is no longer used by your application. It is especially useful for cleaning up legacy code.
As deadcode4j is available via the Maven repository, you can simply run
mvn de.is24.mavenplugins:deadcode4j-maven-plugin:find -Dmaven.test.skip=true
to analyze your project.
deadcode4j will trigger the package phase to be executed for a project (and for all modules listed in a reactor project) before analyzing the output directories. The output will look something like this:
[INFO] --- deadcode4j-maven-plugin:2.1.0:find (default-cli) @ someProject --- [INFO] Analyzed 42 class(es). [WARNING] Found 2 unused class(es): [WARNING] de.is24.deadcode4j.Foo [WARNING] de.is24.deadcode4j.Bar
deadcode4j is tested with Maven 3.0.5, 3.1.1, 3.2.5 & 3.3.9.
