Cannot complete the install because one or more required items could not be found.
Software being installed: Xtend SDK 2.4.0.v201303201134 (org.eclipse.xtend.sdk.feature.group 2.4.0.v201303201134)
Missing requirement: Xtend Standalone Bundle 2.4.0.v201303201134 (org.eclipse.xtend.standalone 2.4.0.v201303201134) requires 'bundle org.eclipse.emf.codegen 2.5.0' but it could not be found
Cannot satisfy dependency:
