title: Jenkins Multibranch Config: How to Filter branches based on variable string?
body: <p>We have Jenkins set up with 7 multibranch pipeline projects, each building off the same git repo, but for different target platforms. Each of these multibranch pipelines builds a number of branches. We currently set which branches each multibranch pipeline builds by using the following property in the multibranch project configuration:</p>
  
  <p><code>Branch Sources -&gt; Git -&gt; Behaviors -&gt; Filter by name (with wildcards)</code></p>
  
  <p>Currently, each multibranch pipeline has the same string of branches in this <code>Filter by name (with wildcards)</code> field. Each time we want Jenkins to start building a new branch, we go through all 7 multibranch project configurations and update this field to include the new branch.</p>
  
  <p>It's a bit of a pain to go through each configuration and change this field every time, since we always want each configuration to have the same list of branches. Is it possible to simply use some type of a variable in this field? This way we only would need to change one location instead of trying to keep 7 different configurations in sync with each other, which is prone to error and also a bit of a pain.</p>
  
  <p>Thanks for your help!
