How can I store shell output into an array in Jenkins?

Question

In my Jenkins pipeline, I'm trying to get this output into an array:

gitBranches  = sh (
script: 'git branch -a',
returnStdout: true).trim()

Is that possible?

Can be done in groovy way:

gitBranchStr  = sh (
script: 'git branch -a',
returnStdout: true)
gitBranchList = gitBranchStr.substring(gitBranchStr.lastIndexOf("*") + 1).split("\n")*.trim()

I think it's better to first get rid of the leading * and then trim - or else you end up with a whitespace before the current branch. And for golfing you could use the spread operator instead of the collect.
