Generating edit/editor project [message #1858337]

Hi,

I'm trying to define a language in xtext where I also want the corresponding .edit and .editor project being generated.

I found an old post form Marc Hamilton where he also tries to achieve this. There the solution is to generate the edit/editor plugins once manuallay after the genmodel has been generted (by xtext).

Unfortunately I don't succeed. Starting from the example that is created by the 'New Xtext Project' wizard in eclipse, I generated the language and using the generated genmodel, I generated the org.xtext.example.mydsl.edit plugin once.

Then I adapt/add the following snippet to the mwe2 file:

language = StandardLanguage {
	...			
	fragment = ecore.EMFGeneratorFragment2 {
		generateEdit= true
	}
}

Executing the mwe2 file leads to:
org.eclipse.emf.common.util.WrappedException: java.io.IOException: The path '/org.xtext.example.mydsl.edit/src/org/xtext/example/mydsl/myDsl/provider/MyDslEditPlugin.java' is unmapped

I assume that xtext tries to generate gthe edit plutin into an non-existing directory. Adding editDirectory = "foo" does not change the error message. It seems to ignore the editDirectory directive.

Any ideas how to solve this e.g. what am I doing wrong?

Regards,
Wilbert

Hi Christian,

Thanks for your reply. Indeed, adding a bean like below did the trick:

    bean = StandaloneSetup {
            scanClassPath = true
            platformUri = ".."
        }

Regards,
Wilbert
