How to run JaCoCo on a Maven project from the command line?

Question

I want to run JaCoCo from the command line on a Maven project without including JaCoCo configuration into the pom.xml.

How do I configure and invoke JaCoCo from the command line like:

$ mvn test <JaCoCo - config params>

In essence, I am looking to get a coverage report for a Maven project without having to manually edit its pom.xml. Invoking JaCoCo directly on the Maven project (without invoking the mvn command would work to.

You can use:

mvn clean org.jacoco:jacoco-maven-plugin:0.8.8:prepare-agent  verify org.jacoco:jacoco-maven-plugin:0.8.8:report

to call jacoco generation directly from command line without any change in your pom file.

You can replace verify by test
