Hi,

I have three use cases for my uml-to-xml acceleo generator.
1) Run it inside eclipse -> works out of the box
2) Export the generator as jar and use it as command line program -> I have troubles...
3) Add the generator to the dependencies of another java plugin-project and generate. Preferable I would also like to export it as runnable jar -> Same troubles Sad

First of all I uncommented the uml stuff in registerResourceFactories and registerPackages. Also I reexport the dependencies of the uml-to-xml generator, to use it in my third use case.

I tried the following steps:
In my first try, after I exported the generator as Runnable-Jar, I got the following error while running it:

C:\Users\home\acceleojava.io.IOException: '/org/tat/pim/uml/gen/xml/main/generate.emtl' not found

        at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:58)

So for my second try, I also checked 'Save as ANT script' and after running this ANT script, the emtl files were included in the jar. But I got the following error:

I added the following code to registerPackages:

resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("emtl", new EMtlResourceFactoryImpl());

Generated everything again and got the following error:

Now I'm stuck. It seems that I have to change the URIConverter, but I don't know how and with what...

Thanks for any help!

Hi,

How are you building your Acceleo generator? You should use the Acceleo maven plugin for that. Have a look at the generator here.

Regards,
