你正在使用的Go版本是什么( go version )?

$ go version 
go version go1.16.5 darwin/amd64

这个问题在最新版本中是否重现？

是的

你正在使用什么操作系统和处理器架构( go env )?

go env 输出

你做了什么？

  1. 在测试文件顶部添加了一个 //+build ignore 构建标志
  2. 运行 go test -v --tags=ignore ../.

你期望看到什么？

我的测试输出

你看到了什么？

go test -v --tags=ignore ../. 输出

ignore是一个保留字，但在许多示例文件中用作“不要构建此项，结束”的标记。我不确定在这里应该怎么做，除了说“不要将ignore用作构建标签的名称”。

忽略是一个保留字，但它在许多示例文件中作为“不要构建这个，结束”的标记。我不确定在这里该怎么办，除了说“不要将ignore用作构建标签的名称”。
也许go命令应该明确地在传递-tags=ignore时出错？这当然要少一些困惑。

值得注意的是，ignore构建标签已经被Go工具以特殊方式处理，例如go mod tidy忽略它。对我来说，让-tags=ignore出错并附带有用的信息是合理的；我见过的所有// +build ignore的使用案例都涉及到直接运行文件来忽略构建约束，例如go run ignored.go。而且，无论如何，标准库都会因为这个构建标签而中断。

我喜欢@mvdan提出的错误信息想法。另外，@tmthrgd,你有没有参考过任何提到这个的文档？我在找，但是找不到这方面的信息。

@mvdan,我认为我们应该继续允许go list -tags=ignored列出这些文件，因为在今天的很多情况下都能正常工作(尤其是在使用-e标志的情况下)。不过我同意，我们可以改进那些实际构建依赖关系的命令的错误信息。
