构建使用 go 模块的项目时，权限被拒绝在 Jenkins 中创建 /go 目录

Question

当我尝试构建一个使用 go 模块的 go Jenkins 项目时，我看到了这个错误：

go: writing go.mod cache: mkdir /go: permission denied

我也看到每次导入都会出现类似的错误：

我正在使用Go Jenkins 插件来更改 Go 版本。

这是我在 Jenkins 管道中的使用方式：

def root = tool name: 'Go 1.14', type: 'go'

withEnv(["GOROOT=${root}", "PATH+GO=${root}/bin", "GOBIN=${root}/bin"]) {
  sh 'go version'
  sh './build.sh'
}

注意：./build.sh 使用模块构建项目

发生了什么，我怎样才能让我的构建工作？

问题在于 GOPATH 仍被定义为 /go。构建过程尝试创建此目录，但 Jenkins 无权创建它。

要解决此问题，请在您的 withEnv 调用中定义 GOPATH，因此最终的 withEnv 代码块如下所示：

withEnv(["GOROOT=${root}", "PATH+GO=${root}/bin", "GOBIN=${root}/bin", "GOPATH=${root}/go"]) {
  sh 'go version'
  sh './build.sh'
}

文档没有提到在这里定义“GOPATH”，所以我花了几天时间才发现这一点。
