mvn install fails with "secret key not available" ?

[jgeewax]

What I did:

$ sudo apt-get install mvn2
$ git clone https://github.com/GoogleCloudPlatform/gcloud-java.git
$ cd gcloud-java
$ mvn install

Error I got:

signing was needed for deploy and I, wrongly, assumed no one should bother
with mvn install (which could have been made to pass with the addition
-Dpgp.skip-true).
I moved the signing to the deploy phase and now install does not try sign
the artifact.

[jgeewax]

just checked - LGTM :)

Above should be -Dgpg.skip=true for those seeing this in a search.
