java.lang.Cloneable

public class JETEmitterTask
extends JETTask

Exposes some functionalities available on the JETEmitter class.

This task is supposed to be executed by a Eclipse driver with the org.eclipse.emf.ant plugin. It is neither necessary to use Ant's task TaskDef to declare this task in a script nor to change the Ant's runtime classpath.

The following command line will start a headless Eclipse instance and run the specified Ant script.

eclipseDir/eclipse -noSplash -data worspaceDir -application org.eclipse.ant.core.antRunner -buildfile antScript

In Windows you should execute eclipsec instead of eclipse in order to have access to the Ant build script console output.

You can also use the Eclipse UI to execute an Ant script containing this task by right-clicking the script and selecting Run As > Ant Build... > JRE > "Run in the same JRE as the workspace".

Usage examples:

 <emf.JETEmitter templateURI="http://www.example.com/jetTemplate.txtjet"
                 newFile="c:\output.txt"/>
 

 <emf.JETEmitter templateFile="jetTemplate.txtjet"
                 newFile="c:\output.txt"/>
 

 <emf.JETEmitter templateURI="d:\templates\jetTemplate.txtjet"
                 newFile="c:\output.txt">
     <variable name="MY_VAR" pluginID="com.myplugin;/>
     <variable name="JUNIT_HOME" pluginID="org.eclipse.jdt.junit;/>
 </emf.JETEmitter>
