A dependency from unsafe.jar to itself is redundant and thus was 
excluded from the returned value of the requires method.  Maybe better 
just to output without any dependence like this:

unsafe.jar
    use.unsafe.UseClassWithUnsafe -> use.unsafe.UseUnsafeClass unsafe.jar

Analyzer.java

  147 if (result.requires.isEmpty() && type == Type.VERBOSE && hasDependences(source)) {
    Is type == Type.VERBOSE necessary?  If hasDependences(source)  returns true,
    "unsafe.jar" is missing for non-verbose mode I assume.

  This long line should be broken into multiple lines.

Maybe good to initialize Stream<Archive> to handle the empty and
non-empty case to avoid duplicate code line 148-149:
    final ArchiveDeps result = results.get(source);
    Stream<Archive> reqs = result.requires().stream();
    if (result.requires().isEmpty()&& hasDependences(source)) {
        reqs = Stream.of(source);
    }
    reqs.sorted(.....


I haven't reviewed the tests.  They are named as closure.  Are these 
tests for the new jdeps enhancement that you are thinking?
