|
58 \fBjdeps\fR [\fIoptions\fR] \fIclasses\fR \&.\&.\&. |
|
59 .fi |
|
60 .sp |
|
61 .TP |
|
62 \fIoptions\fR |
|
63 Command-line options\&. See Options\&. |
|
64 .TP |
|
65 \fIclass\fR\fIes\fR |
|
66 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\&. |
|
67 .SH DESCRIPTION |
|
68 The \fI\fR\f3jdeps\fR command shows the package-level or class-level dependencies of Java class files\&. The input class can be a path name to a \f3\&.class\fR 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, \f3jdeps\fR outputs the dependencies to the system output\&. It can generate the dependencies in DOT language (see the \f3-dotoutput\fR option)\&. |
|
69 .SH OPTIONS |
|
70 .TP |
|
71 -dotoutput <\fIdir\fR> |
|
72 .br |
|
73 Destination directory for DOT file output\&. If specified, \f3jdeps\fR will generate one dot file per each analyzed archive named <\fIarchive-file-name\fR>\&.dot listing the dependencies, and also a summary file named summary\&.dot listing the dependencies among the archives\&. |
|
74 .TP |
|
75 -s, -summary |
|
76 .br |
|
77 Prints dependency summary only\&. |
|
78 .TP |
|
79 -v, -verbose |
|
80 .br |
|
81 Prints all class-level dependencies\&. |
|
82 .TP |
|
83 -verbose:package |
|
84 .br |
|
85 Prints package-level dependencies excluding dependencies within the same archive\&. |
|
86 .TP |
|
87 -verbose:class |
|
88 .br |
|
89 Prints class-level dependencies excluding dependencies within the same archive\&. |
|
90 .TP |
|
91 -cp <\fIpath\fR>, -classpath <\fIpath\fR> |
|
92 .br |
|
93 Specifies where to find class files\&. |
|
94 |
|
95 See also Setting the Class Path\&. |
|
96 .TP |
|
97 -p <\fIpkg name\fR>, -package <\fIpkg name\fR> |
|
98 .br |
|
99 Finds dependencies in the specified package\&. You can specify this option multiple times for different packages\&. The \f3-p\fR and \f3-e\fR options are mutually exclusive\&. |
|
100 .TP |
|
101 -e <\fIregex\fR>, -regex <\fIregex\fR> |
|
102 .br |
|
103 Finds dependencies in packages matching the specified regular expression pattern\&. The \f3-p\fR and \f3-e\fR options are mutually exclusive\&. |
|
104 .TP |
|
105 -include <\fIregex\fR> |
|
106 .br |
|
107 Restricts analysis to classes matching pattern\&. This option filters the list of classes to be analyzed\&. It can be used together with \f3-p\fR and \f3-e\fR which apply pattern to the dependencies\&. |
|
108 .TP |
|
109 -P, -profile |
|
110 .br |
|
111 Shows profile or the file containing a package\&. |
|
112 .TP |
|
113 -apionly |
|
114 .br |
|
115 Restricts analysis to APIs, for example, dependences from the signature of \f3public\fR and \f3protected\fR members of public classes including field type, method parameter types, returned type, and checked exception types\&. |
|
116 .TP |
|
117 -R, -recursive |
|
118 .br |
|
119 Recursively traverses all dependencies\&. |
|
120 .TP |
|
121 -version |
|
122 .br |
|
123 Prints version information\&. |
|
124 .TP |
|
125 -h, -?, -help |
|
126 .br |
|
127 Prints help message for \f3jdeps\fR\&. |
