Question

I am attempting to create a standalone ant build file for android. We are using acceleo to generate code.

Here are the steps i am taking within the build.xml.

1. compile the auto generator
2. Generate the EMTL files
3. Generate the code from the EMTL files

Right now, i can run step 1 and it works fine. Then i run step 2 and it fails with the following errors (Step 2 Errors). And then i can run step 3 and it works fine. I then check all of my files and generated code and everything looks fine. However, those errors from step 2 are really bothering me and i need to get them resolved.

Any help will be greatly appreciated and if you need more information, please let me know.

Posted below are the steps in the build.xml and the errors for step 2.

Answer 1

Removing extra stuff out of the [module generateDataAccessObject(...)] actually fixed the problem. If i only include http://www.eclipse.org/emf/2002/Ecore and http://www.eclipse.org/acceleo/mtl/3.0 then it works.
