1. 拉取代码超时

在拉取代码的时候，有时候由于代码太大，导致jenkins在首次拉取代码的时候，超时异常结束了

一般报错如下：看到接收到82%的时候异常了，太可惜了

解决方法：

• 以使用pipline为例，如果是流水线freestyle的工作流，那么就按照下图的操作添加Advanced clone behaviours

• 设置超时时间，单位是分钟

• 生成pipline脚本

• 将extensions这一段脚本加到pipline的checkout的工作流里面就可以了

extensions: [[$class: 'CloneOption', noTags: false, reference: '', shallow: false, timeout: 10]]
