Problem with splitting sculptor model into different projects

[Kirill Alexandrovsky]

Hello

I have a problem with sculptor's importing mechanism.

I try to make a make multiple projects using archetypes from pure EJB3 tutorial:

• helloworld-parent
• helloworld
  
• helloworld-ear

Model contains just one entity, repository, resource, and service. And it works just fine.

Then I add helloworld-shared project with next structure:

helloworld-shared/src/main/resources
  model-shared.btdesign:
    ApplicationPart MyApp {
        Module shared_model {
            basePackage=org.helloworld
            Entity Employee {
               
                String name
               
                Repository EmployeeRepository {
                    findById;
                    findAll;
                    save;
                    delete;
                }
            }
  model.btdesign: //doesn't build without this file
    import "classpath:/model-shared.btdesign"

    Application MyApp {
        basePackage=org.helloworld
    }

And in business tier project I just have

import "classpath:/model-shared.btdesign"

Application MyApp {

    basePackage=org.helloworld

    Module test1 {
        Service EmployeeService {
            findById => EmployeeRepository.findById;
            findAll => EmployeeRepository.findAll;
            save => EmployeeRepository.save;
            delete => EmployeeRepository.delete;
        }

        Resource EmployeeResource {
            show => EmployeeService.findById;
            showAll => EmployeeService.findAll;
            create => EmployeeService.save;
            delete => EmployeeService.delete;
            update => EmployeeService.save;
        }

        Resource HelloWorldResource {
            void hello;
        }
    }
}

I also add needed dependencies in pom.xml for business tier project. Everything according to Advanced tutorial. Plus disabling generation for the shared part in sculptor-generator.properties.

After that I have two problems. Sculptor cannot find shared model on classpath when building parent project.

[ERROR] Failed to execute goal org.sculptorgenerator:sculptor-maven-plugin:3.1.0:generate (code-generation) on project helloworld: Execution code-generation of goal org.sculptorgenerator:sculptor-maven-plugin:3.1.0:generate failed: org.eclipse.xtext.resource.FileNotFoundOnClasspathException: Couldn't find resource on classpath. URI was 'classpath:/model-shared.btdesign' -> [Help 1]

This issue doesn't happen when I build business tier project separately. But in this case tests begin to fali:

Tests in error:
  testFindAll(org.helloworld.test1.serviceapi.EmployeeServiceTest): Name "MessagingTestBean" not found.
  testSave(org.helloworld.test1.serviceapi.EmployeeServiceTest): Name "MessagingTestBean" not found.
  testFindById(org.helloworld.test1.serviceapi.EmployeeServiceTest): Name "MessagingTestBean" not found.
  testDelete(org.helloworld.test1.serviceapi.EmployeeServiceTest): Name "MessagingTestBean" not found.

testDelete(org.helloworld.test1.serviceapi.EmployeeServiceTest)  Time elapsed: 0 sec  <<< ERROR!
javax.naming.NameNotFoundException: Name "MessagingTestBean" not found.

Can you tell me what can possibly lead to these errors? Maybe some general directions to look into.

Thank you

  model.btdesign: //doesn't build without this file

    import "classpath:/model-shared.btdesign"

    Application MyApp {

        basePackage=org.helloworld

    }

Here the (redundant) "model.btdesign" can be omitted if the Sculptor Maven Plugin is configured to look for "src/main/resources/model-shared.btdesign" instead of its default "src/main/resources/model.btdesign":

<plugin>
	<groupId>org.sculptorgenerator</groupId>
	<artifactId>sculptor-maven-plugin</artifactId>
	<executions>
		<execution>
			<id>code-generation</id>
			<goals>
				<goal>generate</goal>
			</goals>
			<configuration>
				<model>src/main/resources/model-shared.btdesign</model>
			</configuration>
		</execution>
	</executions>
</plugin>

After that I have two problems. Sculptor cannot find shared model on classpath when building parent project.

[ERROR] Failed to execute goal org.sculptorgenerator:sculptor-maven-plugin:3.1.0:generate (code-generation) on project helloworld: Execution code-generation of goal org.sculptorgenerator:sculptor-maven-plugin:3.1.0:generate failed: org.eclipse.xtext.resource.FileNotFoundOnClasspathException: Couldn't find resource on classpath. URI was 'classpath:/model-shared.btdesign' -> [Help 1]

In the POM of Maven Project "helloworld" the Sculptor Maven Plugin needs as a (plugin) dependency of the Maven artefact created by the Maven project "helloworld-shared" (containing the classpath resource "/model-shared.btdesign"):

<plugin>
	<groupId>org.sculptorgenerator</groupId>
	<artifactId>sculptor-maven-plugin</artifactId>
	<executions>
		<execution>
			<id>code-generation</id>
			<goals>
				<goal>generate</goal>
			</goals>
		</execution>
		<dependencies>
			<dependency>
				<groupId>your.groupid</groupId>
				<artifactId>helloworld-shared</artifactId>
				<version>1.0</version>
				<classifier>client</classifier>
			</dependency>
		</dependencies>
	</executions>
</plugin>
