如何编写gradle脚本才能在成功构建时提交当前分支

task commitOnBuild {
    doLast {
        def branch = 'git rev-parse --abbrev-ref HEAD'.execute().text.trim()
        def commitMessage = 'Automatically committed by Gradle build'

        if (branch != 'HEAD') {
            'git add -A'.execute()
            "git commit -m '${commitMessage}'".execute()
            "git push origin ${branch}".execute()
        }
    }
}

// 在构建成功时执行提交任务
build.finalizedBy(commitOnBuild)
