尝试从Acceleo中的uml生成Java类

Question

I have been trying to get going with Acceleo. I use Enterprise Architect to design my classes, and have exported them as XMI.

In Eclipse, when I try to generate even a simple class using Acceleo, I get the following error.

Can anyone advise me as to what I am doing wrong?

Im using:

• Eclipse Kepler

• Acceleo Version: 3.2.2.v20120807-0831

Acceleo doesn't find the URI package you declared. Indeed such a profile ( http://schema.omg.org/spec/XMI/2.1 ) doesn't appear to me to be an Acceleo registered package URIs, as I can't find it either. Did you edited it manually after creating your modules with any other available profile? Maybe this link might help you to shed some light over your question.
