Cloudbees: App Engine Deployment failing

Question

Strange error when deploying to GAE from Cloudbees DEV@cloud Jenkins instances:

[cloudbees-deployer] Deploying as stuart.langridge@PROJECTNAME.com to Google App Engine
[cloudbees-deployer] Deploying PROJECTNAME
[cloudbees-deployer]   Resolved from workspace as /scratch/jenkins/workspace/PROJECTNAME/PROJECTNAME

Recording test results

Now, this used to work. I install node as part of my test scripts, so Jenkins can use casperjs and phantom to run the test suite. However, the app itself doesn't use node (it's Python, on Google App Engine). The two relevant lines seem to be

ERROR: Couldn't find path for tool 'GAE Python SDK 1.7 (latest)' 
com.cloudbees.plugins.deployer.exceptions.DeployException: No {0} SDK available for node.

and I do not understand what's looking for a path, or why there'd be an SDK needed for node. (I think that "node" there does not mean "nodejs"; I think it means "this node that Jenkins is running on; i.e., a computer".)

So, why can't the deployer find an SDK? More importantly, how can I fix it?

AppEngine SDK 1.7 isn't supported anymore, and has been removed from build slaves. Change your jenkins instance configuration to use the 1.8 SDK
