xtend template generator not working in deployed app [message #1811087]

Why would a deployed app be able to run it's generator, but have it's xtend templates not get interpreted?

For example, my generated outputs look like copies of my xtend generator:

??FOR connBundle : PBXAppImpl.getInstance().connectionBundles??
connBundle: ??connBundle.name??
??FOR conn : connBundle.connections??
conn: ??conn.name?? @??conn.hashCode??:
src: ??FOR src : conn.sources?? ??src.name?? ??ENDFOR??
dest: ??FOR dest : conn.destinations?? ??dest.name?? ??ENDFOR??
??ENDFOR??
??ENDFOR??

I've never seen this before, but it's now happening in both my Run Configuration in Eclipse and in my deployed application (whose target is set up with Tycho/Maven).

Xtext 2.14 (installed over 2.12)

Are you sure use configure a proper encoding in your project and Xtend file and build system (especially on windows )

Thank you for helping.

Possibly not. You are talking about the Project created in the user's workspace with the deployed application right?

What should the encoding be?

I'm using the New Project Wizard provided with 2.14 and I had to make a small tweak in that release code to include

projectNatures += #[XtextProjectHelper.NATURE_ID]
builderIds += org.eclipse.xtext.ui.XtextProjectHelper.BUILDER_ID

into the the generateProjects method of the wizard template

Should I be adding a friendly encoding there too somehow?

No the project containing the xtend file. Have a look at it's generated java file (MyDslGenerator.java)

How do you build. What is the encoding in your oroject or workspace ( see properties and preferences )

Thank you for the pointers. It looks like changing the workspace/project text encoding property to UTF-8 was key. I had already changed it for the xtend file in my generator to get it to work, but there needed to be more done.

Doing this in my developer workspace got the Run Config test launch working again.

I also seemed to need to tweak my tycho/maven dsl.parent pom to include:

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

Doing that helped get my deployed application working again.
