Rebuild Project或者Make Project失败

在使用CC时，点击Rebuild Project或者Make Project会失败，会报“Cannot fit requested classes in a single dex file (# methods: 78448 > 65536 ; # fields: 82718 > 65536)”这个错误，分包已经加了，但是运行和打包是没问题的。这是什么问题呢？

Reproduce the failure by using CC with Android Studio's Rebuild Project or Make Project actions, and capture the reported dex method and field limits. Start by tracing the build path involved in those actions and compare it with the already-working run and packaging paths. Done means the cause is identified and the project can rebuild successfully without changing the working behavior.
