| After upgrading ec2 plugin to 1.44 (from 1.43) and Jenkins to 2.182 (from 2.181), EC2 agents failed to connect with an error from agent jar about workDir requiring an argument.
The ec2 configuration I had did not specify any remote FS root (i.e. workDir). I had to explicitly declare the remote FS root for each ec2 pool I have to make them work again. Expected behavior: Empty remote FS root should default to what it used to default to (user home).

Note that I attempted the same without ssh client process, and the result was the same. |
