How to set environment variables in Jenkins?

Question

I would like to be able to do something like:

AOEU=$(echo aoeu)

and have Jenkins set AOEU=aoeu.

The Environment Variables section in Jenkins doesn't do that. Instead, it sets AOEU='$(echo aoeu)'.

How can I get Jenkins to evaluate a shell command and assign the output to an environment variable?

Eventually, I want to be able to assign the executor of a job to an environment variable that can be passed into or used by other scripts.

This can be done via EnvInject plugin in the following way:

1. Create an "Execute shell" build step that runs:

   echo AOEU=$(echo aoeu) > propsfile
   

2. Create an Inject environment variables build step and set "Properties File Path" to propsfile.

Note: This plugin is (mostly) not compatible with the Pipeline plugin.
