jdeps là một công cụ Phân tích phụ thuộc lớp Java , là một công cụ dòng lệnh để hiển thị mức gói hoặc phần phụ thuộc cấp lớp của các tệp lớp Java nhất định. Các lớp đầu vào có thể được cung cấp dưới dạng tên đường dẫn đến .class tệp, một thư mục , một jar fil e hoặc nó sẽ là một tên lớp đủ điều kiện để phân tích tất cả các tệp lớp.

C:\Program Files\Java\jdk-9.0.4>jdeps --help Usage: jdeps <options> <path ...>] <path> can be a pathname to a .class file, a directory, a JAR file. Possible options include: -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. --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. --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. --list-deps Lists the dependences and use of JDK internal APIs. --list-reduced-deps Same as --list-deps with not listing the implied reads edges from the module graph If module M1 depends on M2 and M3, M2 requires public on M3, then M1 reading M3 is implied and removed from the module graph. -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 -m <module-name> --module <module-name> Specify the root module for analysis --multi-release <version> Specifies the version when processing multi-release jar files. should be integer >= 9 or base. 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 c*lasses in that containing archive are analyzed. -q - quiet Do not show missing dependences from --generate-module-info output. -version --version Version information
