JaCoCo not generating jacoco.exec until after skipping JaCoCo execution

Question

I\'m having trouble generating AHP reports via JaCoCo in one of my modules. When the build starts, I see JaCoCo correctly setting argLine with:

[INFO] jacoco.age         


        

Answer 1

Just an addition to the answers already given. It could happen that in your maven-surefire-plugin configuration you already use the argLine configuration to override something like the memory used. If you do so the argline set by jacoco-maven-plugin will not be used failing to generate the jacoco report. In this case assign a property name to the jacoco-maven-plugin config and then reference it in your maven-surefire-plugin argLine parameter.

                        true
                        ${sonar.jacoco.reportPath}
