Usage of generators [message #536550]

Hello,

does anybody know how to add generation of emf bundles from a given genmodel
can be done with Buckminster/Hudson? How can be defined that the bundles to
be generated are not fetched from repositories specified in the rmap file?
And how/when must the ant task be started, is it done automatically during
'perform' or should an additional action call be added to the build step?

Thanks for any suggestions.

Regards

Axel

Hi,
how to use generators is in the buckminster documentation.
Does not however show how to use it to generate bundles from models.

In general:
Add a CSPEX to the component that contains the genmodel.
In this CSPEX add the information about the components that it is
capable of generating.
Add the actions that performs the generation.

This means that when resolution takes place and the resolver has seen
the component with the "generates" then it will know how to obtain them.
The problem is making sure that the resolver sees these before something
is requiring them - sometimes it is required to place the "generates" in
a component that is "above" the others.

Hi Henrik,

thank you for these pointers. They were really helpful, now I coped with
getting the action (specified in the SPEX) called. Unfortunately the ant
task could not be found.
I extracted emf.ant.tasks.jar and moved it into my releng plugin. Then I
tried to reference it with a taskdef like shown below.

<taskdef name="emfGen"
classname="org.eclipse.emf.importer.ecore.taskdefs.EcoreGeneratorTask "
classpath="${WORKSPACE}/com.example.releng/util/emf.ant.tasks.jar;
${WORKSPACE}/com.example.releng/util/importer.ecore.tasks.ja r " />

Any idea what could be wrong here?
The error message is "taskdef class
org.eclipse.emf.importer.ecore.taskdefs.EcoreGeneratorTask cannot be found"

I wondered whether it could be possible to reference the target platform,
but any other approach is welcome, too.

Thanks in advance!

Axel
