Jenkins Multibranch Pipeline with Git Tag Discovery

Be default [Jenkins][1] [multibranch pipelines][2] with git [won't discover and build tags][3].

Following on from [R Tyler Croy][4]'s post about [pipelines with git tags][5].

Here's how you generate a job like that in [JobDSL][6].

The key is that you can't use the obvious `branchSources / git` API. It's a nice shortcut but it doesn't have a `traits` property.

But` branchSources / branchSource / source / git`, however, does!

multibranchPipelineJob('my_repo') {
        factory {
            workflowBranchProjectFactory {
                scriptPath('Jenkinsfile')
            }
        }
        branchSources {
            branchSource {
                source {
                    git {
                        remote(git_url)
                        credentialsId('my\_credential\_id')
                        traits {
                            gitBranchDiscovery()
                            gitTagDiscovery()  // be careful you don't create a build storm!
                            headWildcardFilter {
                                includes('my\_branch1 my\_branches* my_tags* )
                                excludes('')
                            }
                        }
                    }
                }
            }
        }
    }
