UE4源码Xcode编译错误解决：/Mac/XcodeBuild.sh failed with exit code 5

Xcode编译UE4源码的时候报错：

Running command : Engine/Binaries/DotNET/UnrealBuildTool.exe UE4EditorServices Mac Development
ERROR: Unhandled exception: System.IO.IOException: Sharing violation on path /Volumes/UnrealEngine/Engine/Build/JunkManifest.txt
…
Command /Volumes/UnrealEngine/Engine/Build/BatchFiles/Mac/XcodeBuild.sh failed with exit code 5

解决方法

Xcode打开项目后，耐心等待indexing加载完毕再编译。
