CKJM

Version 1.8 2007-07-25

• Contributed code contains Ruby scripts that plot ckjm metrics as charts.
• The DIT calculation now also takes into account classes that are not directly processed. This may require explicitly setting up the java.ext.dirs property so that ckjm can locate the jar files containing those classes. Example:

  java -Djava.ext.dirs=lib -jar ckjm-1.8.jar *.class
  

  In the corresponding ant task, the new extdirs path-like structure of the ckjm task will accomplish the same function. Example:

  <ckjm outputfile="hsqldb.xml" format="xml" classdir="/app/hsqldb/classes">
    <extdirs path="/app/hsqldb/lib" />
    <include name="**/*.class" />
  </ckjm>
