Hi there,

I am generating the model,edit, editor source code using the following EMF
ant task that I have defined:

<project name="Ecore2Java Generation" default="GenerateJava" basedir=".">

<property name="model" value="./model/product.ecore"/>
<property name="genmodel" value="./model/product.genmodel"/>

<taskdef name="emfGen"
classname="org.eclipse.emf.importer.ecore.taskdefs.EcoreGeneratorTask "/>

<target name="GenerateJava">
<echo message="Generate the model,edit and editor Java code from the
ecore model"/>

<emf.Ecore2Java model="${model}"
genModel="${genmodel}"
reconcileGenModel="reload"
generateJavaCode="true"
generateModelProject="true"
generateEditProject="true"
generateEditorProject="true"
modelProject="bt.com.ccm.product"
modelProjectFragmentPath="src">
<arg line="-editProject bt.com.ccm.product.edit src"/>
<arg line="-editorProject bt.com.ccm.product.editor src"/>
</emf.Ecore2Java>
</target>

</project>

The problem is that for the model project generated is not an EMF project
and subsequently does not include the necessary EMF plug-in dependencies.
These results in errors since EMF specific classes cannot be resolved.

Actually the output messages displayed onto the console when running the
task indicate that for the edit and editor projects the ant tasks creates
first an EMF project prior to generating the code; while for the model
project this does not occur.

Does anyone has any idea about this problem?

Thanks,

Achilleas

Achilleas,

Are you generating into an existing folder, perhaps one that even
contains a plugin.xml already, that's not been properly set up?

Hi Ed,

No I am not generating into an existing folder. The projects do not exist
in the Eclipse workspace. They are created when I invoke the ant task
generation.

But for the model project only the JRE dependencies are included in the
project. No plug-in dependencies and therefore I get the erros in the
generated code.

\Any ideas?

Thanks,

Achilleas

Achilleas,

By guess would be that the folder actually exists already. Maybe not in
the workspace, but in the underlying file system, so that when the
project is created in the workspace, there's already old stuff in it.

Hi Ed,

I have back to this issue after undertaking some other work and I still
have the same problem.

The project and the folder do not exist neither in the workspace or the
underlying system.

Do you have any other suggestions? DOes anyone have any other suggestions?

Thanks,

Achilleas

Achilleas,

Are a plugin.xml and a MANIFEST.MF being generated? What do they look like?

Ed,

This is the plugin.xml generated for the model project:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>

<!--
<copyright>
</copyright>

$Id$
-->

<plugin>

<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri="http://www.com.bt/2009/product"
class="product.ProductPackage"/>
</extension>

</plugin>


This is the MANIFEST.MF for the model project:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: %pluginName
Bundle-SymbolicName: bt.com.ccm.product;singleton:=true
Bundle-Version: 1.0.0
Bundle-ClassPath: .
Bundle-Vendor: %providerName
Bundle-Localization: plugin
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Export-Package: product,
product.impl,
product.util
Require-Bundle: org.eclipse.core.runtime,
org.eclipse.emf.ecore;visibility:=reexport
Bundle-ActivationPolicy: lazy

As soon as the model, edit and editor projects are generated and the
errors appear, I configure the build path of the model project adding
merely the "org.eclipse.emf.ecore_2.4.0........." plug-in dependency and
all the errors dissapear and the plug-ins work just fine!

It seems very strange and I have run the ant task so many times but still
the same problem!

Thanks,

Achilleas

So the dependency to get it to compile is there and should work.

But that dependency is already there. It sounds like perhaps the
..classpath file is not being updated, but that should happen
automatically... What if you just invoke PDE Tools->Update
classpath...? Does that do the trick too?

Ed,

Yeah, you are right! That does the trick too!

I am running the ant task from another project and I just noticed that it
generates two projects (actually the one is a copy of the other).

The one is created in the project that contains the ant task and one in
the workspace as normal. If I delete one of the two the other gets deleted
also-very strange for me:)..it seems they are interlinked somehow!

Even if I create an EMF project myself with the appropriate name and run
the ant task from that project it creates other problems. The model
project MANIFEST.MF has an error that I need to resolve; set the
'singleton' directive. And the edit and editor projects errors are because
of access restrictions of the model project that I need to resolve.

Is there a specific way to invoke the ant script? I am including the ant
script..maybe I have something wrong in the script. Honestly don't know:)


<project name="Ecore2Java Generation" default="GenerateJava" basedir=".">

<property name="model" value="./src/model/product.ecore"/>
<property name="genmodel" value="./src/model/product.genmodel"/>

<taskdef name="emfGen"
classname="org.eclipse.emf.importer.ecore.taskdefs.EcoreGeneratorTask "/>

<target name="GenerateJava">
<echo message="Generate the model,edit and editor Java code from the
ecore model"/>

<emf.Ecore2Java model="${model}"
genModel="${genmodel}"
reconcileGenModel="reload"
generateJavaCode="true"
generateModelProject="true"
generateEditProject="true"
generateEditorProject="true"
modelProject="bt.com.ccm.product"
modelProjectFragmentPath="src">
<arg line="-editProject bt.com.ccm.product.edit src"/>
<arg line="-editorProject bt.com.ccm.product.editor src"/>
</emf.Ecore2Java>
</target>

</project>


Thanks,

Achilleas

Achilleas,

Unfortunately I know next to nothing about Ant. :-(

If the *.genmodel already exists, be sure that the properties for where
to generate the results are set properly there in the first place.

Ed it seems that this was actually the problem! I regenerated the EMF
model and deleted the ecore elements to leave only the configuration
information and now the projects are generated just fine!

Maybe there was an error in the previous genmodel i generated.

When I run the EMF ant task is there the option to create the genmodel;
i.e. if I have only the ecore file?

Do you have any idea where should I start for generating the GMF diagram
code now?

Thanks,

Achilleas

Achilleas,

I think it creates the GenModel if it doesn't already exist... I don't
know about GMF ant tasks...

Hi,

it doesn't exist yet as EMF.

there is multiple entries discussing about that in the gmf newsgroup that you can look.

Hi,

I know that an ant task does not exist. I am trying to implement it! Just
see the new post I made in the GMF newsgroup.
