-jar
flag, providing as its argument the location of the file
ckjm.jar
.
Next, you can specify as arguments the Java class files you want
to analyze.
java -jar /usr/local/lib/ckjm-1.5.jar build/classes/gr/spinellis/ckjm/*.class(Replace the sequence
/usr/local/lib/ckjm-1.5.jar
with the actual path and filename of the ckjm version you are using.)
The command's output will be a list of class names (prefixed by the
package they are defined in), followed by the corresponding
metrics for that class: WMC, DIT, NOC, CBO, RFC, LCOM, Ce, and NPM.

java -jar /usr/local/lib/ckjm.jar 'ant-jai.jar org/apache/tools/ant/types/optional/image/Text.class'Finally, instead of specifying the classes to be analyszed as the command's arguments, you pass them (as class files, or as jar file, class file pairs) on the command's standard input. The following example will process all class files located in the build directory.
find build -name '*.class' -print | java -jar /usr/local/lib/ckjm.jarThe program, by default, will not take into account classes that belong to the Java SDK packages. The command-line option switch
-s
, can be used to enable this
processing.
