Duplicate content parser registration [message #1009089]

Hi Ed

Since plugin.xml codegen merging was added (17-Oct-2012), I've been
having to manually delete a duplicate content_parser registration after
each regeneration.

Pre-existing, wanted declaration:

<extension point="org.eclipse.emf.ecore.content_parser">
<parser
contentTypeIdentifier="org.eclipse.ocl.examples.pivot"
class="org.eclipse.ocl.examples.pivot.utilities.PivotResourceFactoryImpl"/>
</extension>

Unwanted merged addition:

<extension point="org.eclipse.emf.ecore.content_parser">

<parser
contentTypeIdentifier="org.eclipse.ocl.examples.pivot"
class="org.eclipse.emf.ecore.xmi.impl.XMIResourceFactoryImpl"/>
</extension>

This behaviour does not seem to affected by the generate bundle manifest
genmodel option, or by an @generated NOT.

Is there some new technique for suppressing the unwanted merged content,
or is it a bug?

Regards

Ed Willink

Ed,

You can turn off Update Classpath if you don't want things like the
plugin.xml and the MANIFEST.MF touched during regeneration at all.
Alternatively I think you can specify something like this to block
subsequent merging while allowing anything else new to be merged in later.

<extension point="org.eclipse.emf.ecore.content_parser">


</extension

Hi

Thanks for the clues. Your suggestion works but gives a warning message
about missing content. The following works.

<extension point="org.eclipse.emf.ecore.content_parser">


<parser
contentTypeIdentifier="org.eclipse.ocl.examples.pivot"
class="org.eclipse.ocl.examples.pivot.utilities.PivotResourceFactoryImpl"/>
</extension>

Regards
