How to check dependencies in generics with ArchUnitTest?-CodePudding

We have a rule that package "foo" should not depend on package "bar"

noClasses()
                .that()
                .resideInAPackage("com.foo..")
                .should()
                .dependOnClassesThat(resideInAPackage("com.bar.."))
                .check(javaClasses);

And we have an interface in "foo" using "bar" in two ways, directly and via generics.

public interface IFoo {

    BarClass getBar();

    Optional<BarClass> getOptionalBar();

    List<BarClass> getListBar();
}

The "BarClass getBar();" is caught by ArchUnitTest, but "Optional getOptionalBar()" and "List getListBar()" doesn't give us any error in the test. Does anybody know how to make them failing too?

ArchUnit 0.20.0 has introduced support for generic return types. With the current version, type arguments of generic method return types should automatically be considered as class dependencies.
