Hi,

I'm trying to join our recently created xtext projects to our main tycho/hudson building.

Existent projects I could run properly, but with a newly created project which I didn't call the mwe2 manually first, I got some build error because a not generated plugin.xml that is being referenced in the build.properties.

If I run mwe2 using the ide before tycho, the problem don't happen.

So, I would like to know what is generated by fornax-oaw-m2-plugin and if I always need to do one first generation at eclipse before setup it to tycho. This way I could know what I need to add to source control, too.

thanks for any help. regards,

Cristiano

well, I just figured out that I hadn't set up the plugin properly. I have removed the execution configuration because this error in m2e:
Plugin execution not covered by lifecycle configuration: org.fornax.toolsupport:fornax-oaw-m2-plugin:3.4.0:run-workflow (execution: default, phase: generate-sources)


After I've included the execution tag:
<plugin>
	<groupId>org.fornax.toolsupport</groupId>
	<artifactId>fornax-oaw-m2-plugin</artifactId>
	<version>3.4.0</version>
	<configuration>
	<workflowEngine>mwe2</workflowEngine>
	<workflowDescriptor>src/org/lunifera/metamodel/dsl/behavior/stories/en/GenerateStoryDsl.mwe2</workflowDescriptor>
	</configuration>
	<executions>
		<execution>
			<phase>generate-sources</phase>
			<goals>
				<goal>run-workflow</goal>
			</goals>
		</execution>
	</executions>
</plugin>


and now I'm getting this error:

Hi Christiano!

The plugin just executes the MWE2 workflow as you would do it from Eclipse. It is not necessary to run the generation once in the IDE before. No generated sources need to be checked in.

Your error simply indicates that the StoryDsl.xtext file is not on the classpath. Find out why. You could enable debug output with "-X", the plugin will print the whole Java command that is executed. Maybe the .xtext file is not in the target/classes of that module?

Kind regards,
~Karsten

Hi Karsten,

It is a kind strange. The package that contains the files are being exported. The plugin could find the .mwe2 but why not the .xtext ?

I've created a little unit test program inside an osgi bundle fragment and I could find and open the xtext file.

About the generation. the first generation include some files inside the src too. that is generated by maven too ?

thanks,
Cristiano

Hi Karsten,

After long hours debugging and researching, I was able to make it work using a hack that I've found in Spray project.

I really didn't like it, but it worked. I have to copy out the .xtext and .mwe2 files to a folder that was added as maven resource.

		<resources>
			<resource>
				<directory>${project.build.directory}/xtext</directory>
			</resource>
		</resources>
		<plugins>
			<!-- Copy all Xtext related sources to separate folder that is registered 
				as resource folder -->
			<plugin>
				<artifactId>maven-resources-plugin</artifactId>
				<executions>
					<execution>
						<id>copy-resources</id>
						<phase>initialize</phase>
						<goals>
							<goal>copy-resources</goal>
						</goals>
						<configuration>
							<outputDirectory>${project.build.directory}/xtext</outputDirectory>
							<resources>
								<resource>
									<directory>src</directory>
									<includes>
										<include>**/*.xtext</include>
										<include>**/*.mwe2</include>
									</includes>
								</resource>
							</resources>
						</configuration>
					</execution>
				</executions>
			</plugin>


Could you explain me, please, why this is being necessary? It is a tycho deficiency or it is fornax-oaw-m2-plugin that is not setting up the classpath properly?


thanks.

Cristiano

Hi,
I had the same problem just now.
What worked for me, was to add the src-Folder as a resource to the maven pom:

<build>
<resources>
<resource>
<directory>src</directory>
</resource>
</resources>
...

Otherwise, the fornax plugin adds the "maven default" path src/main/resources to the classpath and will not find the .xtext-File.
