jdeps(1) Basic Tools jdeps(1) 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 Destination directory for DOT file output. If specified, jdeps will generate one dot file per each analyzed archive named .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 , -classpath Specifies where to find class files. See also Setting the Class Path. -p , -package 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 Finds dependencies in packages matching the specified regular expression pattern. The -p and -e options are mutually exclusive. -include 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.
