java - Proguard : google. gms - 重复的 zip 条目 c.class == zzab.class

Question

我正在尝试设置 proguard 以避免在使用 Dagger 2 + Data 时出现 64k 方法绑定(bind)。

我在 Proguard 中优化了很多行之后遇到了这个问题:

    Copying resources from program jar [\app\build\intermediates\exploded-aar\io.fabric.sdk.android\fabric\1.3.14\jars\classes.jar] (filtered)

* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForJapanDebug'.
> java.io.IOException: Can't write [\app\build\intermediates\transforms\proguard\japan\debug\jars\3\1f\main.jar] (Can't read [\app\build\intermediates\exploded-aar\com.google.android.gms\play-services-basement\9.4.0\jars\classes.jar(;;;;;;**.class)] (Duplicate zip entry [com/google/android/gms/common/internal/c.class == classes.jar:com/google/android/gms/common/internal/zzab.class]))

我研究了一些文章，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。

请知道的 friend 帮我解决

非常感谢，

p/s :

这是混淆文件:

我遇到了同样的问题。对我来说，问题是我还有一些其他的 Google Play 服务依赖项，但版本不同。一旦我确定它们具有相同的版本，问题就解决了。

希望这对某人有帮助。
