【问题描述】：

我在 UE4.26 中使用带有 firebase 插件的 jekins 尝试了 android 包。但是我的 android 打包失败，错误为 3，我尝试查找错误 3，我找不到有关错误 3 的信息，我没有解决方案。请帮帮我。

【问题讨论】：

主要错误是Could not set process working directory to 'Z:\': could not set current directory (errno 3) - 所以问题是你的驱动器 `Z:` 有什么问题，为什么要让 gradle 使用它？

我对 gradle 的了解不够。 Z驱动器是我打包andorid构建时的默认路径。那不是我的意思。但通常 Z 驱动器运行良好@Robert

【参考方案1】：

您需要前往您的 build.gradle 文件（应用程序）并将您的 minSdkVersion 更改为 21。

编码愉快！ :)
