Usage: jdeps <options> <path ...>]
<path> can be a pathname to a .class file, a directory, a JAR file.
Possible options include:
-h -? --help Print this help message
-dotoutput <dir>
--dot-output <dir> Destination directory for DOT file output
-s -summary Print dependency summary only.
-v -verbose Print all class level dependences
Equivalent to -verbose:class -filter:none.
-verbose:package Print package-level dependences excluding
dependences within the same package by default
-verbose:class Print class-level dependences excluding
dependences within the same package by default
-apionly
--api-only Restrict analysis to APIs i.e. dependences
from the signature of public and protected
members of public classes including field
type, method parameter types, returned type,
checked exception types etc.
-jdkinternals
--jdk-internals Finds class-level dependences on JDK internal
APIs. By default, it analyzes all classes
on --class-path and input files unless -include
option is specified. This option cannot be
used with -p, -e and -s options.
WARNING: JDK internal APIs are inaccessible.
-cp <path>
-classpath <path>
--class-path <path> Specify where to find class files
--module-path <module path> Specify module path
--upgrade-module-path <module path> Specify upgrade module path
--system <java-home> Specify an alternate system module path
--add-modules <module-name>[,<module-name>...]
Adds modules to the root set for analysis
--multi-release <version> Specifies the version when processing
multi-release jar files. <version> should
be integer >= 9 or base.
-q -quiet Suppress warning messages
-version --version Version information
Module dependence analysis options:
-m <module-name>
--module <module-name> Specify the root module for analysis
--generate-module-info <dir> Generate module-info.java under the specified
directory. The specified JAR files will be
analyzed. This option cannot be used with
--dot-output or --class-path. Use
--generate-open-module option for open modules.
--generate-open-module <dir> Generate module-info.java for the specified
JAR files under the specified directory as
open modules. This option cannot be used with
--dot-output or --class-path.
--check <module-name>[,<module-name>...
Analyze the dependence of the specified modules
It prints the module descriptor, the resulting
module dependences after analysis and the
graph after transition reduction. It also
identifies any unused qualified exports.
--list-deps Lists the module dependences. It also prints
any JDK internal API packages if referenced.
This option does not show dependences on the
class path or not found.
--list-reduced-deps Same as --list-deps with not listing
the implied reads edges from the module graph.
If module M1 reads M2, and M2 requires
transitive on M3, then M1 reading M3 is implied
and is not shown in the graph.
--print-module-deps Same as --list-reduced-deps with printing
a comma-separated list of module dependences.
This output can be used by jlink --add-modules
in order to create a custom image containing
those modules and their transitive dependences.
Options to filter dependences:
-p <pkg>
-package <pkg>
--package <pkg> Finds dependences matching the given package
name (may be given multiple times).
-e <regex>
-regex <regex>
--regex <regex> Finds dependences matching the given pattern.
--require <module-name> Finds dependences matching the given module
name (may be given multiple times). --package,
--regex, --require are mutual exclusive.
-f <regex> -filter <regex> Filter dependences matching the given
pattern. If given multiple times, the last
one will be used.
-filter:package Filter dependences within the same package.
This is the default.
-filter:archive Filter dependences within the same archive.
-filter:module Filter dependences within the same module.
-filter:none No -filter:package and -filter:archive
filtering. Filtering specified via the
-filter option still applies.
Options to filter classes to be analyzed:
-include <regex> Restrict 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 dependences
-P -profile Show profile containing a package
-R -recursive Recursively traverse all run-time dependences.
The -R option implies -filter:none. If -p,
-e, -f option is specified, only the matching
dependences are analyzed.
-I --inverse Analyzes the dependences per other given options
and then find all artifacts that directly
and indirectly depend on the matching nodes.
This is equivalent to the inverse of
compile-time view analysis and print
dependency summary. This option must use
with --require, --package or --regex option.
--compile-time Compile-time view of transitive dependences
i.e. compile-time view of -R option.
Analyzes the dependences per other given options
If a dependence is found from a directory,
a JAR file or a module, all classes in that
containing archive are analyzed.
