Hi all,
I am having problems with the standalone xtend compiler, using Release 2.5.0 Milestone 3. (2.5.0.v201311121244)
Using the simple MyDsl example project, I extended the file MyDslGenerator.xtend to look like this:
package org.xtext.example.mydsl.generator
import org.eclipse.emf.ecore.resource.Resource
import org.eclipse.xtext.generator.IFileSystemAccess
import org.eclipse.xtext.generator.IGenerator
import org.xtext.example.mydsl.myDsl.Greeting
class MyDslGenerator implements IGenerator {
override void doGenerate(Resource resource, IFileSystemAccess fsa) {
fsa.generateFile('greetings.txt', 'People to greet: ' +
resource.allContents
.filter(typeof(Greeting))
.map[name]
.join(', '))
for(g: resource.allContents.toIterable.filter(typeof(Greeting))) {
fsa.generateFile('org/xtext/example/mydsl/' + g.name.toFirstUpper + '.java', g.generateFile)
}
}
def String generateFile(Greeting g) '''
package org.xtext.example.mydsl;
public class «g.name.toFirstUpper» {
public static void main(String[] args) {
«g.name.toFirstUpper» «g.name.toFirstLower» = new «g.name.toFirstUpper»();
«g.name.toFirstLower».greet();
}
public void greet() {
System.out.println("Hello «g.name»!");
}
}
'''
}
That all works fine as an eclipse plugin; it generates the desired code as expected.
My ant script is based on Boris Brodski's example on xtextcasts.org, and looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!--
NB: This ant script is designed to be run in an eclipse environment, where the required JAR files are
available in the plugins directory. Before running, make sure the ant script runs in the same JRE as
eclipse by selecting the following setting:
- External Tool Configurations....
- JRE tab
- Run in the same JRE as the workspace
This will ensure that the system property "eclipse.home" is set.

If I comment the xpand code out of the file MyDslGenerator.xtend it seems to work fine.
I didn't see this problem with 2.4.x - am I doing something wrong or is this a bug?
Thanks for any help or hints.
Yours,
Adam Crowther
