Classes not being resolved when exporting as plugin [message #1047139]

I got everything working for my language when I launch a new Eclipse instance from the Eclipse I'm working in. Now, I tried to export the project as a plug-in in order to deploy the editor in my Eclipse installation.

I selected my language project, clicked Export... -> Deployable plug-ins and fragments, selected all three projects (mylang, mylang.ui and mylang.tests) and hit finish. It didn't work, and the log for the ui project showed the following errors:

I didn't touch any of these classes, just left what was created by default. What is missing? Is there a better way to deploy the editor in my Eclipse installation?

Hi,

make sure you have build automatically on so that the Xtend builder can create the java classes for the xtend files.
so you have any errors in eclipse?

Yes, I have build automatically turned on.
What do you mean with errors in Eclipse? When I hit "Finish", the errors only appear in the log file.

EDIT: I got it working. I had to check the option "use the class files compiled in the workspace".

and also make sure that xtend-gen is included in the build.properties file.
