EMF JET code generation & classnotfound error [message #418635]

Hi,

I'm trying to apply (JET) dynamics templates from my genmodel, but instead of generating code it generates
ClassNotFoundException exceptions.
Exceptions look like this one :
java.lang.ClassNotFoundException: org.eclipse.emf.codegen.ecore.templates.editor.Plugin_
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at java.lang.ClassLoader.loadClass(ClassLoader.java:251)
...

Only the model generation works. Edit, Editor, and Tests fail.

I'm using Eclipse 3.4M5 with EMF 2.4.0.

Anybody had similar problem or (and) has idea to solve this problem ?

Regards,

Yann

Yann,

Try unfiltering .* resources in the dropdown menu of the nagivator or
package explorer and have a look for compilation errors in the
..JETEmitters project. Perhaps your specialized templates contain errors...

Ok, I've just deleted the .JETEmitters directory, regenerated everything, and it works fine now :)
