Example

The following example shows how to get the information of a launch configuration and start an appropriate java task using the retrieved information:

 
 <target name="run-app">

  <!-- get information from launch configuration  -->
  <launchProperty launchFile="myApplication.launch" 
                  workspace="${workspace.dir}"
                  mainclass="mainclass" 
                  programargs="args" 
                  vmargs="vmargs" 
                  workingDir="workingDir"/>

  <!-- launch with configuration just retrieved -->
  <!-- note: use fork here, otherwise dir has no effect -->
  <java classname="${mainclass}" 
        args="${args}" 
        jvmargs="${jvmargs}" 
        dir="${jvmargs}"
        fork="true"/> 
    	
 </target>
