Ecore2Java Generation task [message #427112]

Mon, 02 February 2009 10:46

Eclipse User

Hi there,

I am using an ant script to generate the java code from an ecore model but
the model, edit and editor projects have dependencies issues.

Does anybody have an idea how to resolve this since I want to fully
automate the process?

Regards,

Achilleas

Hi,

Actually the model project is not generated as a Java project and
therefore its classes cannot be imported by the edit and editor projects!

Any ideas why is that happening? The script is the following:

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

<property name="model" value="./model/cpetypes.ecore"/>
<property name="genmodel" value="./model/cpetypes.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}"
modelProject="bt.com.cpetypes.model"
reconcileGenModel="keep"
generateJavaCode="true"
generateModelProject="true"
generateEditProject="true"
generateEditorProject="true"
modelProjectFragmentPath="src">
</emf.Ecore2Java>
</target>
</project>

Thanks,

Achilleas

Achilleas,

That probably means there was an existing folder in the file system. If
there is already a project, EMF won't change it to become a Java
project, it needs to be one already...

Hi Ed,

Actually what i found out is that the properties Model directory, edit
directory and editor directory generated in the genmodel are not as
supposed. They are generated like this:

Edit Directory /Borland.edit/src
Editor Directory /Borland.editor/src
Model Directory
D:/Borland/Together/workspace/bt.com.cpemss.plugin/bt.com.cp etypes.model/./src/.

So, i am trying first to resolve this! Any suggestions are welcomed!

Thanks,

Achilleas

Achilleas,

The last guy that had odd problems like this found it was related to an
error in the paths he gave for the ecore/genmodel. Perhaps your files
exist with a different case. I don't know much about Ant, so it's hard
to guess...

Yes,

It is related to the paths given for the genmodel, since if I manually
edit these properties in the genmodel and then generate the java code the
resulting projects are just fine!

I am trying to change the paths so that this problem does not arise. I
hope someone that has more experience with ant can give an input on this.

Thanks Ed for the valuable inputs. At least we identified the problem:)

Anyone has any ideas how to set this paths?

I tried also what it is advised at:

http://wiki.eclipse.org/EMF/FAQ#How_can_I_use_the_EMF_Ant_ta sks.3F

to set the editProject and editorProject:

<arg line="-editProject bt.com.cpetypes.model.edit src"/>
<arg line="-editorProject bt.com.cpetypes.model.editor src"/>

But still the model, edit and editor directory properties are set to
something else?

Some help by anyone will be appreciated. I am running the ant file from
eclipse. Should i set anything else?

Thanks,

Achilleas

Sorry for posting so many times but i don't seem to find a solution on how
to set the following properties that are set inside the genmodel:

Edit Directory D:/Borland/Together/bt.com.cpetypes.model.edit/./src/.

Editor Directory D:/Borland/Together/bt.com.cpetypes.model.editor/./src/.

Model Directory
D:/Borland/Together/workspace/bt.com.cpemss.plugin/bt.com.cp etypes.model/./src/.

Once the genmodel is generated if i change those properties to the correct
ones then the generation of the code is just fine.

Still looking for ideas how to do that!!

Hi Achilleas,

I've put together a very simple example that, starting from a .ecore
file, creates a generator model and also generate the java files. All
you will need to do to try it is to edit the .bat file (ECLIPSE_DIR,
WORKSPACE_DIR, and MODEL_DIR variables) before running it. This script
uses the Eclipse Ant runner to execute the build.xml also included in
the zip.

If analyzing these files and the generated .genmodel doesn't help
solving your problem, send me your .ecore file and the directory
structure you would like to end up with. I will see if I can make it work.

FYI, I've used eclipse-SDK-3.4.1 and emf-sdo-xsd-SDK-2.4.1 to test the
files.

Cheers,
Marcelo

Hi Marcelo,

Thanks for the example. I will try that and see if I can resolve my
problem. The problem is though that I am trying to run the ant script
within Borland together from a plug-in which I created.

I am not using a batch file to do that. Despite that fact your example
might give me a clue how to change those paths within Borland together.

I will let you know soon of the result.

Thanks,

Achilleas

Hi Marcelo,

I have tried your example outside eclipse running the batch file with my
working paths and it has generated the code.

It does the same thing if I run it within eclipse, within borland, and via
the headless batch file. To be more precise the .genmodel that it is
generated contains invalid properties. These properties are the Model
directory, the Edit directory and the Editor directory.

It is always appended at the start something like:

If I run it within Eclipse:

Model Directory:D:/PhD/Development
Tools/iMDE/eclipse/workspace/bt.com.cpetypes.metamodel/bt.co m.cpetypes.metamodel/./src/.
Edit Directory: D:/PhD/Development
Tools/iMDE/eclipse/bt.com.cpetypes.metamodel.edit/./src/.
Editor Directory:D:/PhD/Development
Tools/iMDE/eclipse/bt.com.cpetypes.metamodel.editor/./src/.

instead of being the correct ones:

Model Directory: /bt.com.cpetypes.metamodel/src/
Edit Directory: /bt.com.cpetypes.metamodel.edit/src/
Editor Directory: /bt.com.cpetypes.metamodel.editor/src/

If I run it within Borland:

Model
Directory:D:/Borland/Together/bt.com.cpetypes.metamodel/bt.c om.cpetypes.metamodel/./src/.
Edit Directory: D:/Borland/Together/bt.com.cpetypes.metamodel.edit/./src/.
Editor
Directory:D:/Borland/Together/bt.com.cpetypes.metamodel.edit or/./src/.

instead of being again the correct ones:

Model Directory: /bt.com.cpetypes.metamodel/src/
Edit Directory: /bt.com.cpetypes.metamodel.edit/src/
Editor Directory: /bt.com.cpetypes.metamodel.editor/src/

While running the script the code is generated, the edit and editor
projects generated are not even set to be Java projects. Moreover the
genmodel includes this incorrect properties I mentioned above.

When correcting the properties manually from the properties view and
generating the code by right-click command on the .genmodel the code is
perfectly ok and I can run the editor as an eclipse instance.

I don't know why the path is appended and alters the properties. I tried
everything and searched everywhere to find a solution before bothering you
again! If you could provide me with a solution I will be grateful!

How can I attach a zip file while posting:)??

Thanks,

Achilleas

This is simply the different behavior that you get between stand-alone
and Eclipse.

Again, if you aren't running in Eclipse you don't get all the nice
Eclipse effects.

Generally what most people do is preserve their GenModel and reuse it.
The scripts allow you to reload the existing GenModel such that it's
up-to-date with respect to any model changes, but also preserves all the
settings within the *.genmodel.

The path of least resistance is to preserve your *.genmodel file, rather
than creating a new one from scratch...

I use Thunderbird for accessing the newsgroup. It's very nice.

Hi Ed and Marcelo,

Thanks to both of you guys for directing me to the solution to my problem.
I think the problem is not resolved completely, meaning that I have
manually created a .genmodel for which I only set manually these three
properties.

This is performed Ed since in any case either using a batch file, Eclipse
or Borland Together the path to the eclipse, borland or batch file is
appended to these three properties. I don't know if that is how the
impementation of the EcoreGeneratorTask works? I presume it is from the
result.

So, your suggestion Ed to preserve a .genmodel let me to the idea to
create a skeleton .genmodel and via the reconcileGenModel="reload"
property to reload the model changes from the .ecore metamodel by
executing the ant script.

Thanks for both your help,

Achilleas
