How to trigger for multiple branch builds

For exemplification purposes, let’s use 5 branches: master, develop, test1, test2, test3

We need to trigger a build only from two branches: master, develop

• If we leave the field "Branch Options" with the parameter "Build all" - it will build from all branches.

• If we leave the field "Branch Options" with the parameter "Build from" - master - it will trigger to build.

• Jenkins from the master branch, same with develop.

After that, we wonder how to limit the trigger to be triggered only from 2 branches, for example:

• master, develop

• master develop

• origin/master, origin/develop

There are two ways to achieve that:

1. Select “Build from“ and enter branch names separated by white space: "master develop"

2. Select “Build RegExp“ and enter regexp based expression: "master|develop"
