Description Ed Willink

MWE2's StandaloneSetup pioneers an interesting ability for standalone applications to find Eclipse plugins by searching the classpath. This requires plugins to provide a classpath.

org.eclipse.uml2.uml.resources 3.x provided a classpath.
org.eclipse.uml2.uml.resources 4.0.0M2 does not.

Hmm, I don't know where/how the classpath would have been provided, as there isn't a .classpath file in the project (and wasn't in 3.x either) and the build.properties file hasn't changed...

I'm puzzled too. I guess it's a side effect of Import Plugin with Source Folders. Changing to enhancement. I'm just trying to get my MWE scripts working with UML2 4.0.0 and OCL2Java. I've solved missing L2/L3 profiles. Now struggling with a SAXParseException on HTML.Version! Will comment further once working.

In Bug 361063, I've contributed a solution to the problem of URImap initializations that exploits MWE's classpath scanning approach.

It would therefore be helpful if UML resources are findable on the classapth.

This is not 100% necessary; a .classpath line such as 

<classpathentry kind="lib" path="/org.eclipse.uml2.uml.resources"/>

enables run-time access via the classpath, but it appears that this line cannot be defined using the plugin/manifest editor, so it gets lost every time a manifest regenerates its classpath.

So users can gain access, but setting a Build Path property for a plugin is unusual and fragile.

The introduction of UMLResourceUtil.init() means that org.eclipse.uml2.uml.resources has classes and can be on a classpath.

So ... FIXED

Fixed indirectly by bug 364419.
