Project Nature in Xtend
In a plugin project I defines the project and file creation.
I want to define the nature of the project created.
I found this Java code to do (it works fine).

public class WizardNewProject extends BasicNewProjectResourceWizard {

...

@Override
public boolean performFinish() {
super.performFinish();

IProject project = getNewProject();

//Add the Nature
try {
IProjectDescription description = project.getDescription();

String[] natureIds = description.getNatureIds();
String[] newNatureIds = new String[natureIds.length + 1];
System.arraycopy(natureIds, 0, newNatureIds, 0, natureIds.length) ;
newNatureIds[newNatureIds.length - 1] = XtextProjectHelper.NATURE_ID;
description.setNatureIds(newNatureIds);
project.setDescription(description, new NullProgressMonitor());
} catch (CoreException e1) {
e1.printStackTrace();
}

try {
project.refreshLocal(IResource.DEPTH_INFINITE, new NullProgressMonitor());
} catch (CoreException e) {
e.printStackTrace();
}
return true;
}

...

}

I want to write this code in Xtend (for use in Xtext projects)
but the translation I did of Java code Xtend:

override boolean performFinish() {
super.performFinish()
// Add the Nature
var project = newProject as IProject
var description = project.getDescription() as IProjectDescription
var natureIds = description.getNatureIds() as String[]
natureIds.add(XtextProjectHelper.NATURE_ID)
description.setNatureIds(natureIds)
project.setDescription(description, new NullProgressMonitor())
return true
}
...
}

does not work (not the top of the Eclipse Java translator Xtend does not work either)!
No way to access the project from the performFinish () function.
In BasicNewProjectResourceWizard newProject is private but getNewProject () function is public but the call does not work either.
Thank you in advance for your help.

Hi,

your code and the code translated via convert to xtend both compile fine for me.
that is the actual error you get?

maybe it is a buinesslogic problem?
