Mocking static methods with Mockito
# No longer need to use Powermock to mock statics, this is now supported in Mockito with .mockStatic()
# Alternative approach to https://gist.github.com/kevinhooke/b4035faa5f2c215e8166936a44db4fa3
# Requires mockito-inline dependency instead of mockito-core
try (MockedStatic<ClassToMock> mock = Mockito.mockStatic(ClassToMock.class)) {
mock.when(ClassToMock::staticMethod).thenReturn(mockedReturn);

Maven multi-module projects and version properties - flatten-maven-plugin
If building multi-module projects and publishing/installing to a repo, version properties like ${revision} are not
consistently replaced at install time. This results in errors when attempting to refer to one of these modules
as a dependency from another project, and instead of library:1.0.0 resolving, you'll see an error where
it's attempting to reference library:${revision} instead.
See discussion here:
https://stackoverflow.com/questions/41086512/maven-issue-to-build-one-module-using-revision-property
To fix, to need to add the flatten-maven-plugin:
