Code coverage is covered to 0% when I skip tests using -DskipTests and -Djacoco.skip=true

My team need to see the real coverage rate all the time, and it costs too much time if we run all the tests everytime we build and deploy our app.
So we add -DskipTests and -Djacoco.skip=true when we run ‘mvn clean install’.
