roo 1.1.5 sample gwtNoEntities fails to load

I'm building roo samples gwtNoEntities, I'm getting following failure log. Could any one fixed this problem. please let me know.

[ERROR] ScaffoldMobileApp.java:[3,0] packag e com.springsource.foo.client.managed.activity does not exist [ERROR] Scaffol开发者_Go百科dMobileApp.java:[5,45] packa ge com.springsource.foo.client.managed.ui does not exist

gwtNoEntities is as simple as:

project --topLevelPackage com.springsource.foo
persistence setup --provider DATANUCLEUS --database HYPERSONIC_IN_MEMORY 
gwt setup

The error indicates that there are some packages missing, these packages are normally generated by the gwt setup command. Rerun gwt setup in the roo shell or start a new project (new directory) and type the three commands.

Running this worked for me

dependency add --groupId com.google.appengine --artifactId appengine-api-1.0-sdk --version 1.4.0
