Hi,
I'm trying to build my xtext projects with maven (with fornax). This works
fine with a flat directory layout. But when trying to setup the projects
in a hierarchy things get worse.
I guess the reason is that the current working directory stays by the
parent directory during the build and gets not changed when maven walks
down to the child projects. As far as I see xtext expects the current
directory to be the xtext project directory when running the workflow.
I've adjusted the platform uri in the workflow and played around with the
pathRtProject setting and projecNameRt. Now the code generation works
fine. But invoking antlr fails as the path to the grammar files is wrong:
3922 [main] INFO ipse.xtext.generator.LanguageConfig - generating
infrastructure for org.eclipse.vis.blockdiagram.metamodel.BlockDiagram
with fragments : ImplicitRuntimeFragment, ImplicitUiFragment,
GrammarAccessFragment, EcoreGeneratorFragment,
ParseTreeConstructorFragment, Resour

Instead of "../blockdiagram.metamodel/" it needs to be platformUri +
"../blockdiagram.metamodel/"
How do I achieve this? Unfortunately I could not find the source of
de.itemis.xtext.antlr plugin to look at the code.

Christoph
The workflow setup is:
<workflow>
<property
file=" org/eclipse/vis/blockdiagram/metamodel/GenerateBlockDiagram. properties "/>
<!-- ${basedir} comes from maven -->
<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup"
platformUri="${basedir}/.."/>
<component class="org.eclipse.emf.mwe.utils.DirectoryCleaner"
directory="${basedir}/src/generated"/>
<component class="org.eclipse.emf.mwe.utils.DirectoryCleaner"
directory="${basedir}.ui/src/generated"/>
<component class="org.eclipse.xtext.generator.Generator">
<pathRtProject value="../${projectName}"/>
<pathUiProject value="../${projectName}.ui"/>
<projectNameRt value="${projectName}"/>
<projectNameUi value="${projectName}.ui"/>
<mergeManifest value="false"/>
<srcPath value="/src/main/java"/>
<srcGenPath value="/src/generated/java"/>

Hi Christoph,
you can find the sourcecode for the antlr stuff at sourceforge:
http://architecturware.cvs.sourceforge.net/viewvc/architectu rware/xtext_external/
At a first glance, the code looks fine. On the other hand, your mwe file
looks fine, too. If you experience a bug in the generator, please don't
hesitate to file a ticket.
Btw: Please file a bugzilla for the missing sources of the antlr-stuff.
Regards,
Sebastian
