Jenkins inject environment variable

Question

Answer 1

My solution:

Create a "Build a free-style software project".

1. Jenkins > New Item > Build a free-style software project
2. Add 1st step: Execute shell @ Build, and echo key=value pairs to a .properties file
3. Add 2nd step: Inject environment variables, use the .properties file as defined in step 2
4. Add 3rd step: Invoke top-level Maven targets

All custom environment variables are accessible with the key as defined in step #2. This was the only way I found to inject environment variables from shell to java.
