这个jenkinsfile中有保存 制品，
需要注意的是：制品的保存时间，和jenkins丢弃旧的构建参数，相同
局部变量的定义和传递
自定义变量（局部）
def username = 'Jenkins'
echo "Hello Mr.${username}"
环境变量（局部）
withEnv(['MYTOOL_HOME=/usr/local/mytool']){
sh '$MYTOOL_HOME/bin/start'
}
exit code, stdout and stderr 返回值和输出
其做法是，把stdout定向到一个文件，sh 配置 returnStatus: true，它的返回是一个0或非0的整数，然后从文件读取stdout的内容。stderr同理可得。
def status = sh(returnStatus: true, script: "git merge --no-edit $branches > merge_output.txt")
if (status != 0) {
currentBuild.result = 'FAILED'
def output = readFile('merge_output.txt').trim()
slackSend channel: SLACK_CHANNEL, message: "<${env.JOB_URL}|${env.JOB_NAME}> ran into an error merging the PR branches into the ${TARGET_BRANCH} branch:\n```\n${output}\n```\n<${env.BUILD_URL}/console|See the full output>", color: 'warning', tokenCredentialId: 'slack-token'
error 'Merge conflict'
}
sh 'rm merge_output.txt'
