Android dependency 'com.android.support.constraint:constraint-layout' has different version for the compile (1.0.2) and runtime (1.1.2) classpath. You should manually set the same version via DependencyResolution
原来两个 module 中的 gradle 中配置的 com.android.support.constraint:constraint-layout 版本不一样。改成一样就可以了。
