Running External Apps on save in Eclipse

Question

Since we cannot setup Eclipse's RSE to use at the tool for remote editing, I have installed Unison. But how can I get Eclipse to automatically run unison on every file save? Is there an eclipse plugin available for this?

TIA

Answer 1

Depending on the importance, I would write a simple plugin to handle this.

EDIT: All you really need to do is this:

1) Create the plugin from the templates with the RCP\PDE Eclipse install
2) Add the following code to your activator...

@Override
public void start( final BundleContext context ) throws Exception {
 super.start( context );
 plugin = this;

 ICommandService commandService = (ICommandService)plugin.getWorkbench().getService( ICommandService.class );
 commandService.addExecutionListener( new IExecutionListener() {

  public void notHandled( final String commandId, final NotHandledException exception ) {}

  public void postExecuteFailure( final String commandId, final ExecutionException exception ) {}

  public void postExecuteSuccess( final String commandId, final Object returnValue ) {
   if ( commandId.equals( "org.eclipse.ui.file.save" ) ) {
    // add in your action here...
    // personally, I would use a custom preference page, 
    // but hard coding would work ok too
   }
  }

  public void preExecute( final String commandId, final ExecutionEvent event ) {}

 } );
}

You can setup it to be run on every build. Any external tool can be run on every build, just open project's preferences, go to Builders page, click “New…”.
