Generator Problems with xtext 2.1.1 [message #762914]

Hello everyone,

i have some problems with the code generation. when i run my project as an eclipse application, add the src-gen folder - there is no code generate at all. I have generatet a new xtext project, added code to the .xtext file and also to the StatemachineGenerator.xtend. I don't know where to start to find out the problem? Every hint would be appreciated. i have also added a copy of my project-folders (wsp_sn2.zip).

thanks and best regards

My Files

My Statemaschine.xtext

grammar at.xne.sn.Statemachine with org.eclipse.xtext.common.Terminals
 //no link restriction of the forum
generate statemachine "http ://www.xne.at/sn/Statemachine"

Model:
	modules+= Modul+
;
	
Modul:
	'modul' name= ID ';'
	actions+= Action*
	states+= State*	
	transitionconditions+= Transitioncondition*
	transitions += Transition*
;
	
Action:
	'action' name= ID ';'

State:
	'state' name= ID '[' 
	action=[Action] '];'
;

Transition:
	start=[State] '-(' transitCondition=[Transitioncondition]')->' ende=[State] ';'
;

Transitioncondition:
	'transitioncondition' name= ID ';'

My StatemachineGenerator.xtend

/*

package at.xne.sn.generator

import at.xne.sn.statemachine.Modul
import com.google.inject.Inject
import org.eclipse.emf.ecore.resource.Resource
import org.eclipse.xtext.generator.IFileSystemAccess
import org.eclipse.xtext.generator.IGenerator
import org.eclipse.xtext.naming.IQualifiedNameProvider

import static extension org.eclipse.xtext.xtend2.lib.ResourceExtensions.*


class StatemachineGenerator implements IGenerator {
	
	@Inject extension IQualifiedNameProvider nameProvider 
	
	override void doGenerate(Resource resource, IFileSystemAccess fsa) {
		
		    for(e: resource.allContentsIterable.filter(typeof(Modul))) {
		        fsa.generateFile(
		            e.fullyQualifiedName.toString.replace(".", "/") + ".java",
		            e.compile)
		    }
  	}
  	def compile(Modul e) '''
        public class «e.name» { 

        }
    '''
}

In my eclipse environment i have installed the following:

hmmm i get a prozess.java. did you deactivate the compiler in your runtime workspace
window -> prefs -> statemachine -> compiler?
do you have build automatically on in your runtime workspace?
do you get any error messages in your host eclipse console?

OMG, now it works Smile

thanks christian for your hint.

in the meantime i did two steps:
1. i setup a clean eclipse 3.7.1 ide + xtext (described at: http ://www.eclipse.org/Xtext/documentation/2_1_0/005-installation.php). this time i only ticked the Xtext SDK check box, before i had installed the whole package.
2. i did a clean up in my project Wink

and the generated file appeared

thanks again and best regard
