webapp builds a webapp intended for distirbution to a third party 
servlet engine (currently broken see below)

webapp-local - builds a webapp for running locally (i.e. within Jetty)

war - packages a webapp (as in the webapp target) as a war file

Yes, that is the problem. We are currently discussing (on dev) how to 
fail more gracefully in this situation (or even recover automatically).

Yes, you should be able to look at the plugin descriptors page [1] to 
see the maximum plugin version that is compatible with your version of 
Forrest. However, this page seems to have got screwed up and is showing 
the 0.8 release info. However, you can still see that the latest plugin 
version does not work with 0.8.

For example, using Forrest 0.7 you must use projectInfo 0.1.
