Hello all,
I am trying to register an UML-RT Package using the "org.eclipse.papyrus.uml.extensionpoints.UMLLibrary" extension point, so that I can import the package latter as a registered package within my UML-RT model. When I try importing the registered package, it does not import and i get the below error.
Caused by: java.io.FileNotFoundException: /packages/DetectionSensor.uml
at org.eclipse.osgi.storage.url.bundleentry.Handler.findBundleEntry(Handler.java:49)

at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.demandLoadHelper(ResourceSetImpl.java:274)
Eclipse is unable to find the UML file, even though i included it in the binary build.
The path i had given while registering using the extension point is : platform:/plugin/ca.queensu.cs.rover.configuration/packages/DetectionSensor.uml
Any help or pointers will be really helpful !
Thank you.
Regards,
Sudharshan

I'm not sure what's the problem. You can try this: make sure you include the "packages" folder in your build.properties file and also the "plugin.xml" file.
For example
bin.includes = META-INF/,\
plugin.xml,\
about.html,\
packages/
Also, I would recommend that instead of using platform:/plugins/... directly, you create an ecore pathmap mapping like this:
<extension point="org.eclipse.emf.ecore.uri_mapping">
<mapping
source="pathmap://ROVER_LIB/"
target="platform:/plugin/ca.queensu.cs.rover.configuration/packages/"/>
</extension>
and then in the extension point for the library:
<extension point="org.eclipse.papyrus.uml.extensionpoints.UMLLibrary">
<library
description="Rover Library"
name="Rover Library"
path="pathmap://ROVER_LIB/DetectionSensor.uml"/>
</extension>
Although I'm not sure this is necessary, also make your plugin a singleton and activate when a class from the plug-in is loaded (Overview tab of the MANIFEST.MF).
