Skip compilation of integration test in maven project

Question

How do I skip the compilation of integration tests when installing a maven project? I only found -DskipITs and -DskipTests but they only skip the execution, not the compilation. I would like to remove the needed test dependencies.

Answer 1

The property -Dmaven.test.skip=true will skip all tests and also all test compilation, because it is accepted by the failsafe, surefire and compiler plugin. All other properties like -DskipTests will only skip the execution of the tests but the files are still compiled.
