Google Endpoints project Maven-War Failure

[duane musser via StackOverflow]

I have an issue while trying to run a maven install my Google endpoint project. I am building it with maven. The error I get is that maven cannot find a directory. However, before that, the endpoints command was able to write to that same directory.

I am at a loss. Can someone help point me in the right direction? What should I look at next?

Here is the (partial) output: ...snip...
