ANT tasks for Javascript

So far jGrouse tools consist of one ANT task:

• JSMinTask - task to strip away comments and unnecessary whitespace from Javascript code

JSMinTask is a wrapper around org.inconspicuous.jsmin.JSMin by John Reilly, who ported to java original JSMin developed by Douglas Crockford. Their work is covered by license-jsmin.txt for details.

In order to use those tasks, include the following statements into your ANT build file:

<taskdef name="jsmin" 
	classname="jgrouse.jgtools.jsmin.JSMinTask" 
	classpath="${jgtools.jar}">

where property ${jgtools.jar} points to the location of jgtools.jar

The task jsmin accepts the following parameters:

• output - directory containing produced compressed files
  Nested elements:
  • fileset or
  • filelist

Example:

<jsmin output="${buildDir}/out-js">
  <filelist dir="${buildDir}/js/">
    <file name="${buildDir}/js/jgrouse.js"/>
  </filelist>
  <fileset dir="${buildDir}/js/" includes="**/*.js"/>
</jsmin>

This task would process the file jgrouse.js and all *.js files in subdirectories and create compressed files in out-js directory. The structure of output directory matches structure of input directories.
