脚本式语法一般以 node开头
# 指定节点运行任务
执行以下任务，请保证你已经新建了一个节点并 打上了 worker1 的标签；
- 新建一个流水线项目；
- 在流水线选项卡中添加以下代码并运行；
node('worker1') {
stage('Source') {
// 从Git仓库中获取代码
// git 'https://github.com/wyw-s/documents.git';
sh 'echo source'
}
}

如果你不指定worker1标签，或者使用以下方式，那么则默认使用主节点(master)执行任务；
// 不指定标签
node {
stage('Source') {
// 从Git仓库中获取代码
// git 'https://github.com/wyw-s/documents.git';
sh 'echo source'
}
