Jenkins: setting env variable from shell script

Question

I have a bash script that I execute from a Jenkins job, using "execute shell". The script starts an EC2 instance and sets an host variable containing the host name of the new instance.

I would like to set the host name of the new instance (script variable: host ) to a Jenkins environment variable so that I can pass it down to a downstream job (possibly using the Build Flow plugin).

Any idea how to do so?

Thanks

I ended up using a file to propagate data between builds. The first build creates a file containing the information I need to propagate (host name of the newly created EC2 instance). The file looks like:

host.name=ec2.123.3345.amazon.com

I use the EnvInject plugin to read the file and "inject" the properties that are then available in the next build (I'm using the Build Flow Plugin to orchestrate builds).
