I am starting to play with Acceleo 3 in order to automate one repetitive tasks of my daily work as Eclipse plugin developer.
In this context I want to generate several Java classes from an EMF model (xmi file) conform to a given meta model (an ecore file). This is done manually by myself during development stage, no need to programatically generate code.
Using for loops and the file tag, I successfully generated my class files for all model elements. Now I need to generate the content of the file, and for this I need an other for loop inside the file tag. After added this loop I always get many errors (crashing my workbench) of type:
"Error notifying registry change listener."
Any ideas why ? How can I solve this blocking issue please ?
Any help would be really appreciated,
Thanks in advance

This is due to us relying on OSGi's "hot removing" of bundles, but some
plugins aren't being good citizens with their extension points : when we
(Acceleo) remove said plugins, their contributions to the plugin
registry remain... and you get the error you observed.
This is a known Acceleo limitation. As we can't expect the plugin
designers to change their extension points to accept hot
plugging/removing, we need to find a way to workaround this issue ...
but don't expect this workaround to be there before 3.1M6 at least.
For the time being, your options are limited : this issue comes from
Acceleo's dynamic mode. When you launch the generator located in plugin
A, we'll walk the workspace projects in order to check whether one of
them is a dependency of A. If A or one of its dependencies is in the
workspace, and extends an extension point that presents the issue of not
being dynamic, you'll have this error. You can then :
- remove from your workspace the dependencies you don't need to be there
(if they're already installed)
- launch a runtime Eclipse and launch your generation from there (either
with only your generator project in the workspace or, even better,
having defined an action to launch the generation from a right-click, a
This will be investigated (and, hopefully, fixed) before 3.1 goes live,
but I can't give any more precise date.
