I took a look at Vamsi's recent updates to the Tuscany plugin and  
fixed a minor version dependency problem. I can now build, but  
installation fails with a NullPointerException:

Caused by: java.lang.NullPointerException
	at  
org.apache.tuscany.sca.binding.ws.axis2.WSBindingDefinitionsProvider 
$1.run(WSBindingDefinitionsProvider.java:57)
	at  
org.apache.tuscany.sca.binding.ws.axis2.WSBindingDefinitionsProvider 
$1.run(WSBindingDefinitionsProvider.java:56)
	at java.security.AccessController.doPrivileged(Native Method)
	at  
org 
.apache 
.tuscany 
.sca 
.binding 
.ws 
.axis2 
.WSBindingDefinitionsProvider 
.getSCADefinition(WSBindingDefinitionsProvider.java:55)

The NullPointerException is caused because  
WSBindingDefinitionsProvider (line 46) is looking for a  
URLArtifactProcessor for the  
org.apache.tuscany.sca.definitions.SCADefinitions interface. However,  
there isn't a processor defined for this interface. Thus the  
NullPointerException...

Not sure what should be happening, here...
