Hi Mandy,
I am a bit surprised that the verbose option doesn't seem
to have any effect on the output of jdeps -I
I have built 4 jars:
unsafe.jar has some class that depend directly on
sun.misc.Unsafe, and some that don't.
indirect.jar has some classes that depends indirectly
on sun.misc.Unsafe: they depend on classes
from unsafe.jar that depend on sun.misc.Unsafe.
It also has classes that don't depend on sun.misc.Unsafe,
either directly or indirectly.
indirect2.jar also has some classes that depends indirectly
on sun.misc.Unsafe: they depend on classes
from unsafe.jar that depend on sun.misc.Unsafe.
It also has classes that don't depend on sun.misc.Unsafe,
either directly or indirectly.
safe.jar has classes that depends on other classes in
unsafe.jar, indirect.jar, and indirect2.jar
However the classes it depends on do not depend on
sun.misc.Unsafe, either directly or indirectly.
If I run:
$ ./bin/jdeps -I -e sun.misc.Usafe -modulepath ~/test/JdepsTest/dist
-addmods unsafe,safe,indirect,indirect2
Inverse transitive dependences matching sun.misc.Usafe
indirect <- safe
indirect2 <- safe
unsafe <- indirect <- safe
unsafe <- indirect2 <- safe
unsafe <- safe
So it looks like the granurality of the analysis is performed
at module level. Is there anyway to make the analysis at class
level, so that 'safe' isn't reported to depend on sun.misc.Unsafe?
I tried passing -verbose:class or -v but it doesn't appear to have any
effect, the result is always the same.
best regards,

The -addmods option is the same as what the runtime supports so that we
can run jdeps in the same command-line options as runtime. -system is
to specify an alternative java.home.
-inverse option will find the modules that depend on a given root module
directly and indirectly. It’s useful to use with the -requires option
or -package, -regex options:
