Hello,

these are steps how I use XText:
1. I have created a valid grammar "UseCaseTypeModel.xtext". There are no problems with generating the artifacts under Eclipse.
2. I have "GenerateUseCaseTypeModel.mwe2" File. Also no problems with generating the MWE2 workflow via Eclipse.

Extraction from File "GenerateUseCaseTypeModel.mwe2":
var grammarURI = "classpath:/com/ourPackage/dsl/UseCaseTypeModel.xtext"
var fileExtensions = "bm,def"
var projectName = "com.ourPackage.dsl"
var runtimeProject = "../${projectName}"
var generateXtendStub = true

3. Launching the generated IDE Plug-in is also flawless.
4. Creating model files with defined file extensions (bm,def) with IDE assistance is also possible.
5. Generating the target files through an eclipse build of the model files (bm,def) is also correct.

So the manual way over Eclipse works as desired.

The main problem is the full automated way via a Maven build.
The steps 1. + 2. (see first code snippet) are already done and operate correct (using Tycho; offline mode is also ok).

But what has to be done are the steps 4. + 5.
Is there something like a Maven goal to generate the target files out of the model files?


Although I'm not sure I'm going into the right direction I tried the following solution without success:

By the way. With this restriction:
"You can only use links to eclipse.org sites while you have fewer than 5 messages."
it is very difficult to post correct and complete code snippets! Crying or Very Sad

do you get any error message?
did you check svens code from github?
can you share your code?

Thank you for the quick reply. Smile

No, there was no error message within my project.
Unfortunately, none of the expected target files is created (out of the *.bm model files).

So I'm unsure that I use the right approach. Do I?

In Svens example there is a model file "Super.hero" (maven-xtext-example/example-project/src/main/java/)
But I could not see that this example project is part of the parent project (releng).
My expectation is that a java class is generated out of the model file through a Maven build. Is this correct?

When I try to execute Svens example I get the following error:

Hi,

i think the version should be without -SNAPSHOT now.
never the less i just built a own example (not yet cleaned up)

Hello Christian,

I downloaded your example and everything works fine.

The 'greetings.txt' file with the expected content was created in the folder /target/model-gen.

Through your example I'm confident that I'm on the right path.

Thank you very much!

Best regards

Adrian
