About

Clover Maven Plugin is an OpenClover integration with Maven 3.x and Maven 4.x.

This project is open-source, based on the Apache License version 2.0.

Maven 4 compatibility (since 5.1.0)

• Use the clover:setup goal to instrument your code. It works on both Maven 3 and Maven 4:

  mvn clover:setup verify clover:clover
  

• The clover:instrument and clover:instrument-test goals work on Maven 3 only. They fork a build lifecycle and mutate the project model at runtime. Maven 4 treats the project model as immutable during the build, so these mutations no longer reach the plugins running in the forked lifecycle. Instead of silently producing a wrong build, both goals now fail on Maven 4 with a message pointing to clover:setup.

• Repository pollution protection is now enabled by default (maven.clover.repositoryPollutionProtection changed from false to true). Because clover:setup instruments sources in the main lifecycle, running install or deploy together with it would put instrumented classes into your local ~/.m2 cache or into a binaries repository - such a build now fails with an explanatory message. Run your build up to the verify phase, or set -Dmaven.clover.repositoryPollutionProtection=false if installing instrumented artifacts is intentional.
