Has the share module extension maven archetype been ported to the new sdk yet? It seem one can only create amps or all-in-one project with the new SDK.
You can create an AMP for the Share tier using the AMP archetype in the SDK. It works for creating both repo AMPs and Share AMPs. It creates the exact same folder structure in both cases. But if you change the alfresco.client.war setting to share you'll be able to run integration tests with your AMP applied to the Share WAR. Works great.
