绝对詹金斯管道/时髦菜鸟在这里，我有一个舞台

stage('Building and Deploying'){
    def build = new Build()
    build.deploy()
}

使用共享库，其源在Build.groovy这里：

def deploy(branch='master', repo='xxx'){
    if (env.BRANCH_NAME.trim() == branch) {
        def script = libraryResource 'build/package_indexes/python/build_push.sh'
        // TODO: Test out http://stackoverflow.com/questions/40965725/jenkins-pipeline-cps-global-lib-resource-file-for-shell-script-purpose/40994132#40994132
        env.PYPI_REPO = repo
        sh script
    }else {
        echo "Not pushing to repo because branch is: "+env.BRANCH_NAME.trim()+" and not "+branch
    }
}

问题是，当无法将构建推送到远程存储库时（请参见下文），阶段仍然最终显示成功。

如何使shell脚本的退出代码冒泡并使阶段失败？
