jdeps [options] classes ...
options Command-line options. See Options.
classes Name of the classes to analyze. You can specify a class that can be found in the class path, by its file name, a directory, or a JAR file.
-dotoutput <dir>
Destination directory for DOT file output. If specified, \f3jdeps will generate one dot file per each analyzed archive named <archive-file-name>.dot listing the dependencies, and also a summary file named summary.dot listing the dependencies among the archives.
-s, -summary
Prints dependency summary only.
-v, -verbose
Prints all class-level dependencies.
-verbose:package
Prints package-level dependencies excluding dependencies within the same archive.
-verbose:class
Prints class-level dependencies excluding dependencies within the same archive.
-cp <path>, -classpath <path>
Specifies where to find class files. See also Setting the Class Path.
-p <pkg name>, -package <pkg name>
Finds dependencies in the specified package. You can specify this option multiple times for different packages. The \f3-p and \f3-e options are mutually exclusive.
-e <regex>, -regex <regex>
Finds dependencies in packages matching the specified regular expression pattern. The \f3-p and \f3-e options are mutually exclusive.
-include <regex>
Restricts analysis to classes matching pattern. This option filters the list of classes to be analyzed. It can be used together with \f3-p and \f3-e which apply pattern to the dependencies.
-jdkinternals
Finds class-level dependences in JDK internal APIs. By default, it analyzes all classes specified in the \f3-classpath option and in input files unless you specified the \f3-include option. You cannot use this option with the \f3-p, \f3-e, and \f3-s options. Warning: JDK internal APIs may not be accessible in upcoming releases.
-P, -profile
Shows profile or the file containing a package.
-apionly
Restricts analysis to APIs, for example, dependences from the signature of \f3public and \f3protected members of public classes including field type, method parameter types, returned type, and checked exception types.
-R, -recursive
Recursively traverses all dependencies.
-version
Prints version information.
-h, -?, -help
Prints help message for \f3jdeps.

\f3Analyzing the immediate dependencies of a specific class in a given classpath, for example the \f3com.sun.tools.jdeps.Main class in the tools.jar file.
