Cannot use jacoco JVM args and surefire JVM args together in maven

Question

I am using maven with the jacoco plugin to generate code coverage metrics. I am having some difficulty in configuring the surefire plugin with the java opt

Answer 1

Since the jacoco-maven-plugin:prepare-agent goal executes before the maven-surefire-plugin, try adding the ${argLine} variable into the argLine value set by the maven-surefire-plugin.

Example:

  maven-surefire-plugin
  2.12.1
  
    -server -ea -XX:MaxPermSize=256m -Xmx4g -XX:-UseSplitVerifier ${argLine}
  

I had the same problem and this solution worked for me, without any need to reconfigure other sections of the POM.
