"K3 Project" wizard with "User Ecore Basic Aspects With Melange" template leads to invalid Melange file

[ebousse]

When creating a new "K3 Project" with the "User Ecore Basic Aspects With Melange" template, the generated melange file has several problems, including:

• a wrong import (MetamodelExtensions does not exist anymore): import static extension fr.inria.diverse.melange.lib.MetamodelExtensions.*
• outdated keywords, such as metamodel (instead of language) or ecore (instead of syntax)
• an error in the transformations on MyMetamodelMT that "cannot be resolved as a type, even after generating the language runtime, for some reason

Example:

package packageName

import static extension fr.inria.diverse.melange.lib.MetamodelExtensions.*

metamodel MyMetamodel {
	ecore "platform:/resource//as/model/My.ecore"
	exactType MyMetamodelMT
}


transformation execute(MyMetamodelMT mymodel) {
	val root = mymodel.contents.head as MyMetamodel

	print("root: ")
	println(root)
}

@Main
transformation main() {
	val m1 = MyMetamodel.load("input/Simple.xmi",      MyMetamodelMT)
	
	execute.call(m1)
}
