我正在尝试为iOS应用程序设置CI环境。到目前为止，我已经从命令行获得了xcodebuild来正确构建测试版本，但是当Jenkins尝试执行它时，我在控制台中读取了以下内容：

Started by user anonymous

    at au.com.rayh.XCodeBuilder.perform(XCodeBuilder.java:224)

有什么想法吗？我对詹金斯（Jenkins）相当陌生，但我已尽我所能用Google
Fu回答了这个问题，但没有成功。我最初确实是通过手动安装Jenkins（从技术上来说是自制的）遇到了这个问题，但是最近使用了OSX安装程序，并且导致了同样的错误。

我猜想这与Unix / Linux / OSX权限比Jenkins / Xcode有更多关系，但是没有足够的专业知识来确定这一点。

编辑

项目目录权限设置为775。

我还尝试过更改Jenkins运行用户的所有权。

这是当我尝试以守护程序用户身份运行xcodebuild时的输出（$ sudo -u daemon xcodebuild）：
