Hi, I configured the root pom.xml in a project to test my DSL plugin via Maven, I followed the doc: https://www.eclipse.org/Xtext/documentation/350_continuous_integration.html#standalone-build.
But when I do:

mvn clean generate-sources

No code is generated, it seems that it does not recognize my .dsl file (main.dsl).

Here is the output of the command:

$ mvn clean generate-sources

In the Eclipse it works fine generating all the expected code.
I am using and xcore module in my grammar.
Heare is my pom.xml:

did you run maven with -X to see if there can be any resources found and if the correct folders are checked?
i also wonder what
<artifactId>br.com.acme.trierdsl.model</artifactId>
is doing

Thank you for the reply Christian.
If I not put the br.com.acme.trierdsl.model dependency in the pom.xml, some errors occur because it does not find classes that exists in my xcore project:

so model contains your metamodel. then its fine.
that is the output with -X and model?

there should be something like this in the log

It seems be specting that may main.dsl file should be in the dir: ./src/main/java/

But I want that the main.dsl stay in the root project togetter with my root pom.xml file.

my-project
--pom.xml
--main.dsl

So for tests, I put the main.dsl file into the dir ./src/main/java and the .dsl file was collected, but some erros occurs because the use of xcore model project:

if you use an external metamodel make sure it is registered
e.g. by patching standalonesetup

Ok, the use of an external metamodel I solved:

/**
 * Initialization support for running Xtext languages without Equinox extension
 * registry.
 */
public class TrierDSLStandaloneSetup extends TrierDSLStandaloneSetupGenerated {

	@Override
	public void register(Injector injector) {
		if (!EPackage.Registry.INSTANCE.containsKey(ModelPackage.eNS_URI)) {
			EPackage.Registry.INSTANCE.put(ModelPackage.eNS_URI, ModelPackage.eINSTANCE);
		}

		super.register(injector);
	}

	public static void doSetup() {
		new TrierDSLStandaloneSetup().createInjectorAndDoEMFRegistration();
	}
}

But one more question, how can I stay the file main.dsl inside the root of my project and not in the src/main/java folder?

Good question
I am not sure if this is possible
Maybe you can set the sourceRoots list

Yes, now it is working like a charm with Maven. Thank you very much Christian.
This is my final root pom.xml, now the file main.dsl stay at the root of project and it is collected by the xtext-maven-plugin:
