∟"jdeps -verbose" - Class Level Dependencies of Class File

This section provides a tutorial example on how to use 'jdeps -verbose' command to show class level dependencies of a given Java class file.

The default behavior of the "jdeps" command is to show package level dependencies, which tells you what packages are needed to run the given class.

If you want to see what actual classes that are needed to run the given class, you can use the "-verbose" option.

herong> jdeps -verbose ImportTestA.class

ImportTestA.class -> java.base
ImportTestA.class -> not found
   ImportTestA        -> com.herongyang.util.ClsA   not found
   ImportTestA        -> com.herongyang.util.ClsB   not found
   ImportTestA        -> java.lang.Object           java.base
   ImportTestA        -> java.lang.String           java.base

As you can see from the output:

The first 2 lines are showing module level dependencies.
The other 4 lines are showing class level dependencies. So the given class "ImportTestA" needs 4 other classes to run.
