Hi,

I've created a M2T transformation and I need to call it from another application (outside Eclipse). I'm following the steps listed here (http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.acceleo.doc%2Fpages%2Freference%2Fstandalone.html) but i get this exception:

Previosly I was getting a different exception. I solved it by including the library org.eclipse.ocl.common in the project.

I don't know what is wrong, can you help me?

Thanks a lot!

Keep on going. Add org.eclipse.core.runtime to your project.

It is much easier to make your project a Plugin project so that Eclipse
sorts out your class-path for you.

Thanks for your answer, Ed.

I should have said that I already have added org.eclipse.core.runtime to the project. In fact, I have added every org.eclipse.core.runtime.* jar that I've found...

How do I make my project a Plugin project? I export my acceleo project as a "Deployable plug-ins and fragments". Should I export it as a Runnable jar?

Hi

In the Package Explorer select a non-plugin project and do
Configure->Convert to Plugin Projects.

See other threads for advice on deployment.

I'm sorry but I don't understand it. I started my project (in Eclipse) by choosing New->Acceleo Project and there is no "Convert to Plugin Projects" option available. What kind of Acceleo project I'm supposed to use in order to be able to apply "Convert to Plugin Projects"?

I appreciate your help, thank you very much (and please excuse me for my bad English).

Hi

Sorry, an Acceleo project is already a plugin project. The problem is
that the way you run the transformation does not use Eclipse
capabilities so you need to do everything the hard way.

Thanks again for your answers, Ed.

I think my project finally works fine. In case that someone is interested, the jars that you have to add (besides the ones listed in http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.acceleo.doc%2Fpages%2Freference%2Fstandalone.html) are:
org.eclipse.core.runtime
org.eclipse.ocl.common
org.eclipse.osgi

Hi

Thanks for the reference. I understand your legitimate confusion now.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=387973

raised to see if we can return to the earlier requirements.

Hi,

The inclusion of these three new "required at runtime" jars is a regression. Commented on the bug mentionned by Ed. o.e.core.runtime at least we can remove, I'd need to track down what forces us to have ocl.common and osgi too in order to determine whether these regressions can be resolved or if we have to live with them.
