Running an intersection of tests using Junit and Maven

Question

I have a number of tests identified using the Spring @IfProfileValue flag

@IfProfileValue{"a", "c"}
@Test
public void testA{ Do Stuff }

@IfProfileValue{"a", "b"}
@Test
public void testB{ Do Stuff }

@IfProfileValue{"a", "b"}
@Test
public void testC{ Do Stuff }

@IfProfileValue{"b"}
@Test
public void testD{ Do Stuff }

I can run all the tests using

mvm clean install -Dtest-group=a -Dtest-group=b

I want to run only the tests that match @IfProfileValue={"a","b") (Test B/C) so is there a way to run only an intersection of these two values using maven?

Edit: You can annotate the class with @ProfileValueSourceConfiguration@ and provide your own implementation ofProfileValueSource`, as described in this answer.

Looks like is not possible with Maven alone. It looks like it can build array from multiple arguments with same name:

mvn test -Dtest-group=a -Dtest-group=c

will ran test annotated with @IfProfileValue(name = "test-group", values = {"c"}). Neither comma notation will work, it will treat 'a,c' as literal:

    mvn test -Dtest-group=a,c
