Is there a simple way to not build the test classes?
mvn clean install -Dmaven.test.skip=true
I found a work-around in another question, which actually overrides a plugin execution by adding the following snippet in your pom.xml by default:
org.apache.maven.plugins
maven-compiler-plugin
default-testCompile
none
This seems to work but definitely does not disable phase but disables the default actions that a plugin defines at a specific phase.
