[Xcore] Problem with a package starting "http://" [message #893994]

Hi,

Is there a way to specify a package named "http://www.eclipse.org/xcore" in Xcore because it currently gives me the following error: "missing EOF at ':'".

@GenModel(basePackage="org.eclipse.xcore")
package http://www.eclipse.org/xcore

It seems that with Xcore we should use uri like "org.eclipse.xcore" but my application uses an uri handler and an uri like is converted during the resolution since it is detected as a relative uri.

org.eclipse.emf.common.util.URI.createURI("org.eclipse.xcore").resolve(org.eclipse.emf.common.util.URI.createFileURI("C:\\some\\stuff\\here"))
RESULT:	 (org.eclipse.emf.common.util.URI) file:/C:/some/stuff/org.eclipse.xcore

org.eclipse.emf.common.util.URI.createURI("http://www.eclipse.org/xcore").resolve(org.eclipse.emf.common.util.URI.createFileURI("C:\\some\\stuff\\here"))
RESULT:	 (org.eclipse.emf.common.util.URI) http://www.eclipse.org/xcore

Regards,

Stephane Begaudeau

You're trying to specify the EPackage.nsURI. You can use @Ecore
annotations for things like the nsPrefix and the nsURI.

@Ecore(nsURI="http://whatever", nsPrefix="whatever")
package org.example.tree

The XPackage name itself must always be a qualified name; the last
segment determines the EPackage.name and the renaming segments determine
the GenPackage.basePackage.
