Task

org.eclipse.emf.ant.taskdefs.EMFTask

org.eclipse.emf.ant.taskdefs.codegen.ecore.GeneratorTask

org.eclipse.emf.importer.java.taskdefs.JavaGeneratorTask

public class JavaGeneratorTask
extends GeneratorTask

Generates source code from models specified using Annotated Java. Exposes some functionalities available on the JavaImporterApplication class - check its printUsage() method for detailed information on the arguments you can use with this task.

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 example:

 <emf.Java2Java genModel="/lib/emf/lib.genmodel">
 

 <emf.Java2Java genModelPath="/lib/model/lib.genmodel" 
                modelProject="c:/lib" 
        <arg line="-packages http://www.example.eclipse.org/Library"/>
 </emf.Ecore2Java>
 

Different than the other EMF Generator tasks, this one requires the model specification files, Annotated Java, to be located in a workspace Java project. The genModelPath attribute should be used to indicated the workspace absolute path of the GenModel. Also, if the genModel's project doesn't exist in the workspace (indicated by workspaceDir in the command line above), the modelProject attribute should be used to indicate the model's location. This directory should contain all the Eclipse's necessary files (such as ".project" and ".classpath") to define this project as a valid Java project.

Also, the following attributes cannot be used within this task:

• model
• genModel
• modelProjectFragmentPath

Since:

2.3.0
