No. I don't have. I have written the below code to execute when I click on an option convert2bin from context menu. But it is not executing I assume. It is not showing anything on console. How can I debug my plugin?

Please let me know is there thing wrong with my code:

package com.prolifics.jpl.ui.handler

import java.io.BufferedReader
import java.io.InputStreamReader
import org.eclipse.core.commands.AbstractHandler
import org.eclipse.core.commands.ExecutionEvent
import org.eclipse.core.commands.ExecutionException
import org.eclipse.core.commands.IHandler
import org.eclipse.core.resources.IFile
import org.eclipse.core.resources.IProject
import org.eclipse.core.resources.IResource
import org.eclipse.core.resources.IWorkspace
import org.eclipse.core.resources.IWorkspaceRoot
import org.eclipse.core.resources.ResourcesPlugin
import org.eclipse.core.runtime.NullProgressMonitor
import org.eclipse.ui.IEditorPart
import org.eclipse.ui.handlers.HandlerUtil

class GenerationHandler extends AbstractHandler implements IHandler {
override Object execute(ExecutionEvent event) throws ExecutionException {
val IEditorPart activeEditor = HandlerUtil.getActiveEditor(event);
val IFile file = activeEditor.getEditorInput().getAdapter(IFile) as IFile;
val IWorkspace workspace = ResourcesPlugin.getWorkspace();
val IWorkspaceRoot root = workspace.getRoot();

if (file != null) {
val IProject project = file.project

/*********************** File Input Stream Start :::::::::::::: **********************************/
val String cmd = "\""+root.getRawLocation()+file.project.fullPath.toString()+"/jpl2bin.exe\""+" -b -f -p "+file.location;
val Process p = Runtime.getRuntime().exec(cmd);
val BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
val BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
val sInput = stdInput.readLine()
System.out.println(sInput);
val sError = stdError.readLine()
System.err.println(sError);
project.refreshLocal(IResource.DEPTH_INFINITE, new NullProgressMonitor());
/************************* File Input Stream End :::::::::::::: ***********************************/
}
return null;
}
}

Hi Christian,

My functionality in GenerateHandler.class is working fine and I am getting converted .bin file also. But when I am failing to convert in console it is not showing up the errors that I place System.out.println() statement.

Hi Christian,

Generally when we building xtext project we will have all the xtext related artifacts will be in one Eclipse application and editor will be opened in run time application. If we write any system.out.println statements in any of the classes it will be shown in xtext project console, but not on run time application console. Is there any way to show errors on run time application

Since this is not xtext related you should look ask elsewhere eg in the rcp
forum or google

Hi Christian,

This is not I want. I want to show error messages that I added in xtext project code. So that code is in my plugin. After installing the plugin, I am using that installed editor but it is not showing error that I have added in plugin code. I want to display that error message in currently running editor console. I can set console output within the plugin but how can I configure outside the plugin?
