jdeps是一个java类依赖分析工具，它是一个命令行工具，用于显示给定java类文件的包级别或类级别依赖关系。输入的类可以是一个.class文件的路径名，一个目录，一个jar文件，或者是一个完全限定的类名来分析所有的类文件。
"jdeps"自jdk 8以来已经包含在jdk安装中，并且它由"%java_home%\bin\jdeps.exe"程序文件表示。如果我们在"path"环境变量中包含了"%java_home%\bin"目录，我们将运行"jdeps --help"命令以查看所有选项的完整列表。

无论从何种情形出发，在目前校长负责制的制度安排下，中小学校长作为学校的领导者、管理者和教育者，其管理水平对于学校发展的重要性都是不言而喻的。从这个角度看，建立科学的校长绩效评价体系以及拥有相对应的评估手段和工具，有利于教育行政机关针对校长的管理实践全过程及其结果进行测定与衡量，做出价值判断和评估，从而有利于强化学校教学管理，提升教学质量，并衍生带来校长转变管理观念，提升自身综合管理素质。
下面，我们可以通过使用"jdeps --help"命令来查看选项列表。
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
