Hello,
I have a created an EMF project containing an ecore file. It is exported in the plugin.xml file:

<plugin>

   <extension point="org.eclipse.emf.ecore.generated_package">
      <package
            uri="http://softeng.polito.it/moma/des"
            class="it.polito.softeng.moma.des.des.DesPackage"
            genModel="model/des.genmodel"/>
   </extension>

</plugin>

I created then an XPand project, added the project containing the ecore file as dependency and checked that the EMF typesystem is used in the configuration.

When I create an XPand template I do not have access to my ecore package. It is not listed in autocompletion when I use the directive "import".

What should I check? What am I missing?

Thank you,

Federico

P.S. I am using Xpand 0.7.2

If you have generated Java code you have the option to either use the
emf metamodel adapter or the JavaBeans metamodel adapter. I recommend to
use the latter, because it then you don't have an impedance missmatch as
soon as you switch to java (i.e. JAVA extensions). Also the tooling is a
bit better, because it leverages JDT.

If you use Java the imports are of the form:

<<IMPORT my::java::pack>>

if you use ecore the form is:

<<IMPORT packageName>>

Note that it is the package's name not its URI.

Does that help?

It helps because the JavaBeans metamodel is working, I still do not understand why the EMF metamodel do not but now I am not stuck.

Once again thank you Sven!
