刚更新为Android Studio 3.3 RC 2＆gradle tools to 5.1，它开始出现以下错误，
No such property: dir for class: org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection
* What went wrong:
A problem occurred configuring project ':app'.
> groovy.lang.MissingPropertyException: No such property: dir for class: org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection
知道这有什么解决方案吗？
我正在使用
com.android.tools.build:gradle:3.4.0-alpha08
