使用Jenkins DSL插件进行稀疏签出？

job('job1') {    description 'sparse checkout example'    scm {        git { reference('/build/jenkins/prebase.git') configure { git ->     git / 'extensions' / 'hudson.plugins.git.extensions.impl.SparseCheckoutPaths' / 'sparseCheckoutPaths' {         ['mypath1', 'mypath2', 'mypath3'].each { mypath ->  'hudson.plugins.git.extensions.impl.SparseCheckoutPath' {      path("${mypath}")  }         }     } }        }    }}
