# If -Dmaven.test.skip=true (or simply -Dmaven.test.skip) is specified,
# the test-jars aren't built, and any module that relies on them will
# fail its build.
# In contrast, when you use -DskipTests, Maven does not run the tests,
# but it does compile them and build the test-jar, making it available
# for the subsequent modules.
