Questions tagged [jacoco-maven-plugin]

A maven plug-in which provides the JaCoCo agent to automated tests and allows basic report creation.

This plugin lets the build process load the agent runtime in the pre-test phases, allowing additional configuration in the file, and generate test documentation in the verify phase.

Usage

The Maven plug-in can be included in your build with the following declaration:

<plugin>
  <groupId>org.jacoco</groupId>
  <artifactId>jacoco-maven-plugin</artifactId>
  <version>0.7.8</version>
</plugin>

To receive a full list of goals and available parameters you can use maven-help-plugin:

mvn help:describe -Dplugin=org.jacoco:jacoco-maven-plugin -Ddetail
