Maven build from existing .ecore/.genmodel? [message #1814110] Tue, 03 September 2019 19:29 Go to next message
Eclipse UserFriend
Hi all,

I'm resurrecting an old xtext project. My strategy is to use the tooling to create a new one (using the latest version of Xtext), then copy the existing dsl (*.xtext file) source into the new project. Everything is looking pretty good, but it appears that the maven pom files are not generating Java sources from the .ecore/.genmodel files.

I'm deducing this because when I generate from the IDE (open .genmodel, expand root node, right click on first node, then "Generate Model Sources"), then go to the command line and run just "mvn package", it builds ok. However, if I issue "mvn clean package", the build fails because the Java EMF files are not being generated.

How do I configure my pom to generate Java EMF sources during the generate-sources phase? The existing pom is pretty much exactly as it was generated by the eclipse project creation wizard. Portion of pom.xml:
			<plugin>

The pom.xml looks as I would expect. This should launch the GenerateDomain.mwe2 generator workflow during the generate-sources phase. Within that workflow the EMF sources should be generated from the genmodel using the org.eclipse.emf.mwe2.ecore.EcoreGenerator component.

Class io.yaktor.dsl.domain.ecore.domain.AmountField is a defined in file model/domain.ecore. When I look in target/classes, there are no classes in io/yaktor/dsl/domain/ecore/domain. Here is my .mwe2 file:
module io.yaktor.dsl.domain.GenerateDomain

import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*

var rootPath = ".."

Workflow {

				}
			}

			}

		}
	}
}


Anyone have any tips here?

where is your EcoreGenerator component in the workflow?

Obviously, not present. :P

Recall, however, that I'm not generating my EMF .ecore/.genmodel. I'm using my own .ecore & .genmodel file (although I feel like the .genmodel file could be generated from the .ecore file, but that's another story).

Do I need to add an EcoreGenerator to my workflow in this scenario?

I added
	component = EcoreGenerator {
		genModel = "platform:/resource/io.yaktor.dsl.domain/model/domain.genmodel"
		srcPath = "platform:/resource/io.yaktor.dsl.domain/src-gen"
	}

to my .mwe2 (after the XtextGenerator, thank you https://www.eclipse.org/forums/index.php?t=msg&th=1095261&goto=1795421&#msg_1795421 very much), and everything is working like a charm.
