Trigger JaCoCo independent of Sonar

Based on the previous configuration, JaCoCo will trigger with the test goal.

mvn clean test

View report at ‘target/site/jacoco/index.html’

Trigger JaCoCo and then Sonar

mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent install -Dmaven.test.failure.ignore=true

mvn sonar:sonar \
  -Dsonar.projectKey=org.example:codequality \
  -Dsonar.host.url=http://localhost:9000 \
  -Dsonar.login=$SONAR_TOKEN

Important!

Make sure each test starts with "test" otherwise JaCoCo will ignore it.

Pitest

Trigger Pitest and then Sonar

mvn org.pitest:pitest-maven:mutationCoverage

mvn sonar:sonar -Dsonar.pitest.mode=reuseReport

View report at ‘target/site/pit-reports/index.html’
