maven - What is the difference between "-Dmaven.test.skip.exec" vs "-Dmaven.test.skip=true" and "-DskipTests"?

Question

I am not sure what the difference between the maven directives -Dmaven.test.skip.exec and -Dmaven.test.skip=true -DskipTests are. Both seem to suppress the testing cycle.

Answer 1

"maven.test.skip.exec=true" the tests get compiled, but not executed.

"maven.test.skip=true" doesn't compile or execute the tests.

"-DskipTests" is the same as "maven.test.skip.exec=true"
