这个问题在这里已有答案：
Facebook SDK出了问题。当我安装这个我得到错误：无法将类转换为dex格式。安装了plagins：Unity IAP 1.16，Facebook SDK 7.13.0，Google Play Service 0.9.50，Appodeal 2.8.45。 Unity 2017.1.2p3。 jdk1.8.0_181和最新版本的sdk工具没有相同的文件或文件，有不同的版本。 Here is the link for pastebin with error
CommandInvokationFailure: Unable to convert classes into dex format.

You may try using multi-dex. If multi-dex is enabled then the list of classes for the main dex list is too large.

几天前我遇到了同样的问题。这是你的错误：
Too many field references to fit in one dex file: 86260; max is 65536.
您使用的插件都有自己的dex文件，组合大小，特别是在使用GooglePlayGames等时，可以快速提升。
您可以通过将构建设置中的构建类型从Internal切换到Gradle来绕过此问题。
如果您仍然无法正确构建它，您可能需要考虑删除一些插件，如果可以的话。 （我知道这可能不是你想要的方法）。
我最终删除了GooglePlayGames插件，这也减慢了我的构建和应用程序。
