在构建使用Go模块的项目时，权限被拒绝在Jenkins中创建/ go目录

如何解决在构建使用Go模块的项目时，权限被拒绝在Jenkins中创建/ go目录

当我尝试构建使用go模块的go Jenkins项目时，看到此错误：

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

每次导入我也看到类似的错误：

我正在使用Go Jenkins插件来更改Go版本。

这是我在Jenkins管道中使用它的方式：

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

正在发生什么，如何使我的构建正常工作？

解决方法

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

要解决此问题，请在您的GOPATH调用中定义withEnv，这样最终的withEnv代码块将类似于：

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

文档中没有提及定义“ GOPATH”，因此花了我几天时间才发现。
