我构建 CI 服务器并使用 Xcode bot 构建我的项目。我有一个问题，为什么机器人需要这么长时间才能集成（超过 30 分钟）。似乎 Xcode 机器人必须检查所有源代码才能为每个集成构建。即使我在清理项目后从头开始正常构建也只需要大约 15 分钟。第二次集成只是比第一次快一点。我想知道当 Xcode bot 集成时会发生什么。是检查每个集成的新源代码还是只更新旧源代码？为什么要花这么多时间？

我有一个类似的问题。结果发现目录名称源代码在 CI 服务器上被检出损坏。我从位于MyProject - iOS目录中的项目创建了 Xcode Bot，此信息被传送到没有正确处理空格的 bot。

如果您查看日志，您将看到目录名称被转义到MyProject%20-%20iOS然后再次进入MyProject%2520-%2520iOS.

为了解决这个问题，我不得不删除机器人，将存储库目录名称从 更改MyProject - iOS为MyProject并从头开始创建机器人。
