1.错误现象

新电脑环境，安装完Android Studio，配置好环境，导入本地的项目(多module)，编译报如下错误：
What went wrong:
A problem occurred configuring project ':app'.
> A dependency must not be empty

Exception is:
org.gradle.api.ProjectConfigurationException:<81 internal lines>
A problem occurred configuring project ':app'

2.解决方案

主要是修改配置，Android Studio中
File -> Settings -> Experimental -> Gradle
选中第二个，即：Configure all Gradle tasks during Gradle Sync(this can make Gradle Sync slower)

设置好后，点击Apply -> OK，后重新点击Sync Project with Gradle Files按钮，进行同步。
