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.

JaCoCo works by instrumenting the virtual machine before tests are run. Normally one configures the Surefire plugin to include some additional args and use a JVM agent, or to rewrite the byte code of the classes to do something equivalent.

I would check this answer: How to configure JaCoCo maven plugin from command line

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
