jenkins pipeline notes

获取触发用户：

def BUILDER_USER = "${currentBuild.getBuildCauses()[0].userId}"

由上游项目触发时获取上游项目构建信息和触发用户：

def BUILDER_USER = "${currentBuild.getBuildCauses()[0].userId}"
if (BUILDER_USER == "null") {
    if (currentBuild.upstreamBuilds[0]) {
        BUILDER_USER = "${currentBuild.upstreamBuilds[0].buildCauses.userId[0]}"
    }
}
