我们正在从 Android Gradle 插件 2.3.3 迁移到 Gradle 插件 3.0.1。我们的应用程序由应用程序模块和库模块组成。多个依赖项是可传递的（使用api关键字），但甚至使用implementation没有帮助。全部更改后compile-键入对新依赖项的依赖关系，调试构建效果良好。然而，使用 Proguard 的发布版本显示了数千个警告（在 2.3.3 上一切顺利）
特别是，我不明白为什么当库中的 Android 类依赖于程序中的 Android 类时我们会遇到这样的问题（这里只是几个例子）：
Warning: library class android.app.ActionBar$LayoutParams extends or implements program class android.view.ViewGroup$MarginLayoutParams
Warning: library class android.app.ActivityManager$TaskDescription extends or implements program class android.os.Parcelable
Warning: library class android.widget.Toolbar depends on program class android.view.ViewGroup$LayoutParams
总体而言，以下类型的警告不会出现在 Gradle 插件 2.3.3 上（因此，Proguard 已配置）：
Warning: there were 72 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning: there were 1373 instances of library classes depending on program classes.
You must avoid such dependencies, since the program classes will
be processed, while the library classes will remain unchanged.
(http://proguard.sourceforge.net/manual/troubleshooting.html#dependency)
Warning: there were 1056 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile the code.
