git - Jenkins + git : "tell me who you are" error, 为什么要打标签？

Question

刚刚在 Ubuntu 12.04 中安装了 Jenkins，我想创建一个简单的构建，它只是克隆一个项目并构建它。

它失败了，因为它不能标记。它不能标记，因为它错误地说“告诉我你是谁”显然是因为我没有设置 git 设置 UserName 和 UserEmail。

但是，我不需要设置这些，Jenkins 只会克隆存储库，如果它不打算推送更改，为什么它需要凭据，为什么它根本需要做一个标签？

在提取/克隆 repo 时标记的想法对于大多数 Build Scheduler 都很常见:
Hudson-Jenkins，还有CruiseControl (构建标签由 labelincrementer 决定)，或 RTC Jazz Build Engine (where they are called "snapshots") .

想法是将输入的持久记录设置为构建。
这样，您 pull 的代码(即使未标记)也会由构建调度程序自动为您标记，以便稍后能够返回到该特定构建。

如果设置了该策略(总是在构建之前标记)，那么 Jenkins 将需要知道你是谁才能创建一个 git 标记(它是一个附加了作者的 git 对象:user。姓名 和 user.email)。

但是，如“Why hudson/jenkins tries to make commit?”中所述:

Checks "Skip internal tag" config under "Advanced..." in section "Source code management".

这应该避免您似乎不需要的额外标记步骤。
