I like short version: mvn clean install -DskipTests
It's work too: mvn clean install -DskipTests=true
If you absolutely must, you can also use the maven.test.skip property to skip compiling the tests. maven.test.skip is honored by Surefire, Failsafe and the Compiler Plugin.
mvn clean install -Dmaven.test.skip=true
and you can add config in maven.xml
