Jenkins 构建报错：index-pack died of signal 15

坦白背景

主要看到的报错内容是这一块

error: index-pack died of signal 15
11:18:19  fatal: index-pack failed

11:18:19  ERROR: Error cloning remote repo 'origin'

其实往上面翻一翻就可以看到精准的报错，是 clone 仓库的时候超时导致的

11:18:19  ERROR: Timeout after 10 minutes
11:18:19  ERROR: Error cloning remote repo 'origin'

去 gitlab 查看，发现这个仓库有 1.8G 那么大，git 和 jenkins 不在同一个公有云，带宽（只有1MB，实际均值在 500KiB/s）的限制，导致 10分钟根本拉不完

解决方案

方案一

让开发整理自己的 git 仓库，把仓库缩小

方案二

增加超时时间

pipeline - checkout scm

增加 extensions: [[$class: 'CloneOption', timeout: 60]] 指定超时时间，单位是分钟，默认是 10分钟

checkout scm: [$class: 'GitSCM', extensions: [[$class: 'CloneOption', timeout: 60]], userRemoteConfigs: [[credentialsId: 'deploy', url: "${GIT_URL}"]],  branches: [[name: "${GIT_BRANCH}"]]], poll: false
