Xtext 2.8.4 with Maven but without Tycho [message #1724105]

Hello,

I would like to provide a maven artifact of my language (based on the terminal grammar) in order to run the generator in other maven projects. What is the best way to do so with Xtext 2.8.4 and without Tycho (no p2 dependencies)?

I have tried using Xtext 2.9.1 with the new project wizard (only maven), migrated all custom files, removed tycho and changed packaging to jar; but when I run "mvn compile" I get a nearly never ending list of the following errors (by the way: generation with eclipse is working):

[ERROR] resolution of uriFragment '|24' failed. 
java.lang.UnsupportedOperationException: TODO: import a functional handle on the type resolution that delegates to the best available

Hi,

you can use the 2.9.1 wizard to generate a maven module with no tycho
(choose maven as build System and source layout)
and apply the Workaround in https://www.eclipse.org/forums/index.php?t=msg&th=1074746&goto=1723381&#msg_1723381

Hello Christian,

thank you for your suggestion. I created a new project, applied the workaround and copied my dsl. Till then, a "mvn compile" works just fine. But after copying the generators, an OutputConfigurationProvider and a Validator I get the following errors:

[INFO] --- xtend-maven-plugin:2.9.1:compile (default) @ edu.hm.dsl.barrakuda ---
[ERROR] resolution of uriFragment '|24' failed.
java.lang.UnsupportedOperationException: TODO: import a functional handle on the type resolution that delegates to the best available (current, but evolving) result

How can I debug in order to find the "bad" xtend-generator-file or config (there are no warnings/errors in eclipse)?

I have no idea on that. If mvn and eclipse behave differently it is
definitively a bug. What you can try to comment out stuff in the generator
until it works. Or you start with a empty generator and and stuff method by
method

Till now, not everything is copied back to the new project, but its working. In the custom OutputConfigurationProvider I have defined a custom-config in order to clear a specific path. With the open Eclipse Application and my language I can run the clean with "project -> clean...", but how can I do this with the main-class of the language (without eclipse)?

Do I have to write a method on my own using:

fileAccess.deleteFile(fileName, outputConfiguration);

Thanks. I thought xtext would be a little bit more generic.

the problem is: in eclipse this is handled by the builder. standalone you have none.

Indeed, I saw it in the cleanOutput-method of the BuilderParticipant-class. This was, why I asked.
