我们正在从Android Gradle插件2.3.3迁移到
Gradle插件3.0.1。我们的应用程序由一个应用程序模块和一个库模块组成。几个依赖项是可传递的(使用 api 关键字连接(，但即使使用 implementation 使它们不传递也无济于事。将所有compile类型依赖项更改为新依赖项后，调试构建效果很好。但是，使用 Proguard 的发布版本会显示数千条警告(在 2.3.3 上一切顺利(
特别是，我不明白为什么我们会遇到这样的问题，当库中的 Android 类依赖于程序中的 Android 类时(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，还有下一种类型的警告不会出现在 Gradle 插件 2.3.3 上(因此，Proguard 已经配置(：
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.

-dontwarn android.**
不会解决你的问题。您需要查看依赖项树并找到导致问题的库。
例如，在我的情况下，它是
+--- com.foursquare:foursquare-android-oauth:1.0.3
| --- com.google.android:android:4.1.1.4
| +--- commons-logging:commons-logging:1.1.1
| +--- org.apache.httpcomponents:httpclient:4.0.1
| | +--- org.apache.httpcomponents:httpcore:4.0.1
| | +--- commons-logging:commons-logging:1.1.1
| | --- commons-codec:commons-codec:1.3
| +--- org.khronos:opengl-api:gl1.1-android-2.1_r1
| +--- xerces:xmlParserAPIs:2.6.2
| +--- xpp3:xpp3:1.1.4c
| --- org.json:json:20080701
所以你需要排除这个库的com.google.android
implementation ('com.foursquare:foursquare-android-oauth:1.0.3'){
exclude group: 'com.google.android'
}
快速修复：我在升级到 Gradle 插件 3.0.0 时遇到了这个问题，一个快速的解决方案是将其添加到您的 proguard 文件中，
-dontwarn android.**
这应该也适用于 3.0.1。
推荐：当您使用的库未从支持库中引用 android 类或引用已弃用的类时，会发生这种情况。我的猜测是，
com.github.tony19:logback-android-core
您正在使用的导致这种情况，您可以删除此依赖项并尝试重建。如果这没有帮助，您可以尝试删除您正在使用的任何其他库，但它们最近没有更新。
