NAME
jdeps - Java class dependency analyzer.
SYNOPSIS
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.
DESCRIPTION
The jdeps command shows the package-level or class-level dependencies of Java class files.
The input class can be a path name to a .class file, a directory, a JAR file, or it can be
a fully qualified class name to analyze all class files. The options determine the output.
By default, jdeps outputs the dependencies to the system output. It can generate the
dependencies in DOT language (see the -dotoutput option).
OPTIONS
-dotoutput <dir>
Destination directory for DOT file output. If specified, jdeps 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 -p and -e options are mutually exclusive.
-e <regex>, -regex <regex>
Finds dependencies in packages matching the specified regular expression pattern.
The -p and -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 -p and -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 -classpath option and in input files unless you specified
the -include option. You cannot use this option with the -p, -e, and -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 public
and protected 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 jdeps.
EXAMPLES
Analyzing the dependencies of Notepad.jar.
$ jdeps demo/jfc/Notepad/Notepad.jar
demo/jfc/Notepad/Notepad.jar -> /usr/java/jre/lib/rt.jar
<unnamed> (Notepad.jar)
-> java.awt
-> java.awt.event
-> java.beans
-> java.io
-> java.lang
-> java.net
-> java.util
-> java.util.logging
-> javax.swing
-> javax.swing.border
-> javax.swing.event
-> javax.swing.text
-> javax.swing.tree
-> javax.swing.undo
Use -P or -profile option to show on which profile that Notepad depends.
$ jdeps -profile demo/jfc/Notepad/Notepad.jar
demo/jfc/Notepad/Notepad.jar -> /usr/java/jre/lib/rt.jar (Full JRE)
<unnamed> (Notepad.jar)
-> java.awt Full JRE
-> java.awt.event Full JRE
-> java.beans Full JRE
-> java.io compact1
-> java.lang compact1
-> java.net compact1
-> java.util compact1
-> java.util.logging compact1
-> javax.swing Full JRE
-> javax.swing.border Full JRE
-> javax.swing.event Full JRE
-> javax.swing.text Full JRE
-> javax.swing.tree Full JRE
-> javax.swing.undo Full JRE
Analyzing the immediate dependencies of a specific class in a given classpath, for example
the com.sun.tools.jdeps.Main class in the tools.jar file.
$ jdeps -cp lib/tools.jar com.sun.tools.jdeps.Main
lib/tools.jar -> /usr/java/jre/lib/rt.jar
com.sun.tools.jdeps (tools.jar)
-> java.io
-> java.lang
Use the -verbose:class option to find class-level dependencies or use the -v or -verbose
option to include dependencies from the same JAR file.
$ jdeps -verbose:class -cp lib/tools.jar com.sun.tools.jdeps.Main
lib/tools.jar -> /usr/java/jre/lib/rt.jar
com.sun.tools.jdeps.Main (tools.jar)
-> java.io.PrintWriter
-> java.lang.Exception
-> java.lang.Object
-> java.lang.String
-> java.lang.System
Use the -R or -recursive option to analyze the transitive dependencies of the
com.sun.tools.jdeps.Main class.
$ jdeps -R -cp lib/tools.jar com.sun.tools.jdeps.Main
lib/tools.jar -> /usr/java/jre/lib/rt.jar
com.sun.tools.classfile (tools.jar)
-> java.io
-> java.lang
-> java.lang.reflect
-> java.nio.charset
-> java.nio.file
-> java.util
-> java.util.regex
com.sun.tools.jdeps (tools.jar)
-> java.io
-> java.lang
-> java.nio.file
-> java.nio.file.attribute
-> java.text
-> java.util
-> java.util.jar
-> java.util.regex
-> java.util.zip
/usr/java/jre/lib/jce.jar -> /usr/java/jre/lib/rt.jar
javax.crypto (jce.jar)
-> java.io
-> java.lang
-> java.lang.reflect
-> java.net
-> java.nio
-> java.security
-> java.security.cert
-> java.security.spec
-> java.util
-> java.util.concurrent
-> java.util.jar
-> java.util.regex
-> java.util.zip
-> javax.security.auth
-> sun.security.jca JDK internal API (rt.jar)
-> sun.security.util JDK internal API (rt.jar)
javax.crypto.spec (jce.jar)
-> java.lang
-> java.security.spec
-> java.util
/usr/java/jre/lib/rt.jar -> /usr/java/jre/lib/jce.jar
java.security (rt.jar)
-> javax.crypto
Generate dot files of the dependencies of Notepad demo.
$ jdeps -dotoutput dot demo/jfc/Notepad/Notepad.jar
jdeps will create one dot file for each given JAR file named <filename>.dot in the dot
directory specified in the -dotoutput option, and also a summary file named summary.dot
that will list the dependencies among the JAR files
$ cat dot/Notepad.jar.dot
digraph "Notepad.jar" {
// Path: demo/jfc/Notepad/Notepad.jar
"<unnamed>" -> "java.awt";
"<unnamed>" -> "java.awt.event";
"<unnamed>" -> "java.beans";
"<unnamed>" -> "java.io";
"<unnamed>" -> "java.lang";
"<unnamed>" -> "java.net";
"<unnamed>" -> "java.util";
"<unnamed>" -> "java.util.logging";
"<unnamed>" -> "javax.swing";
"<unnamed>" -> "javax.swing.border";
"<unnamed>" -> "javax.swing.event";
"<unnamed>" -> "javax.swing.text";
"<unnamed>" -> "javax.swing.tree";
"<unnamed>" -> "javax.swing.undo";
}
$ cat dot/summary.dot
digraph "summary" {
"Notepad.jar" -> "rt.jar";
}
