Missing ecore file with standalone generation [message #1087659]

I have a standard xtext project in eclipse. I am using Eclipse 4.3 and Xtext 2.4.2. When I generate the language infrastructure inside of Eclipse it works great and get my generated code including a .genmodel file and a .ecore file. When I use the standalone package and generate the language infrastructure via Maven I don't get the .ecore file and the generation fails with errors? I am using 2.4.2 of the standalone jar. I followed a fairly well known example found on GitHub with the single change of upgrading the Xtext version to 2.4.2. How can I get this .ecore file to generate so the build passes? Thanks in advance.

Hi

I looks like you mix up some things. On the one hand there is the
maven plugin for Xtend (is that what you mean with standalone ?) To
generate the Xtext language (and the score derived from it) you need
run the workflow via maven this is done via the fornax plugin see
https://github.com/aphethean/xtext-maven-examples

I am indeed using that GitHub example with the fornax plugin. That is where the .ecore file is not being generated. The file is generated when I generate through eclipse.

I have attached the full error output from maven to the post since I can't put it inline because it has links and I am a new member.

It seems to boil down to this:

Caused by: java.util.MissingResourceException: The string resource '_UI_OK_diagnostic_0' could not be located
