我正在尝试设置proguard，以便在我使用64k methods + Dagger 2时避免问题Data Binding。
我在Proguard中的许多优化行后得到了这个问题：
Copying resources from program jar [\app\build\intermediates\exploded-aar\io.fabric.sdk.android\fabric\1.3.14\jars\classes.jar] (filtered)
Copying resources from program jar [.gradle\caches\modules-2\files-2.1\com.parse.bolts\bolts-android\1.4.0\cc174c559b5177982887bf6e1b76003aebad9516\bolts-android-1.4.0.jar] (filtered)

我研究了一些文章并知道它可能与Duplicated jar问题有关，但我不知道在哪里正确设置exclude。
任何知道的人，请帮我解决。
非常感谢，

这是proguard file：

我有同样的问题。对我来说，问题是我还有其他一些Google Play服务依赖项，但版本不同。一旦我确定他们有相同的版本，问题就解决了。
希望这有助于某人。

在app.gradle中，您需要将以下条目移动到文件末尾：
apply plugin: 'com.google.gms.google-services'
