Ahh, my mistake, since all my slaves are Amazon EC2 VMs and don't exist except 
when they are needed, I assumed the master did all polling :-)

no, polling occurs on last available workspace, that may be a slave.

git-plugin 2.0 is using remote polling "ls-remote" by default, you force the 
legacy mode setting "Force polling using workspace" option
BUT a simpler option is for you to install git on master !

Polling has always run on the master IIRC, otherwise it wouldn't be possible 
for the master to know when to fire up a slave to run a job.

Hello,

I just upgraded several of my plugins including git (2.0), ssh-credentials 
(1.5.1), scm-api (0.2), and git-client (1.4.6).  I'm on Jenkins 1.509.3
Now, polling fails as shown below:

I suspect that the polling mechanism is now attempting to run on the 
server--whereas, before, it ran on the slave.
The Git commands are going to fail if they run on the server, because it 
doesn't have Git installed.
 
Does anyone have an idea of how I can get past this problem?

Thank you.

Steve K.
