I am new to Eclipse and Acceleo, and I have been trying to complete the First Generator Model Tutorial. I am using Kepler 4.3 and Acceleo 3.3.0. I am following the tutorial that generates java code from uml. The link is http://wiki.eclipse.org/Acceleo/Getting_Started. But when I try to run the generate.mtl file, the error log gives me the message:

Couldn't load class org.eclipse.acceleo.module.sample.main.Generate from project org.eclipse.acceleo.module.sample
It also gives me the warning:

Couldn't load class org.eclipse.acceleo.module.sample.main.Generate. Check that its containing package is exported.

I have put the [comment @main/] below the template line and do all the steps in the tutorial, i really have no idea what the problem is.

I have searched the Internet and seems like there are not so many topics about the problem.

I would appreciate any help or feedback.

The same problem with me. I would appreciate any help as well.

I stepped back to Juno (E4.2 and Acceleo 3.3.2). It does not work as I expected from previous versions, but it works.

Regards,
Siegfried

Hi,

This issue can appear sometime because the Eclipse Platform cannot find the manifest in the imported example (IIRC). Try to close and open the project or remove it from the workspace without deleting it and reimport it.

I am facing same problem..I reimported the projects but still getiing same error.

Please advice- what should I do to solve this problem?

I guess it is because class is not found at runtime. please suggest proper class path setting.
