Square 的 Okio 库引用中的 Android-Studio-1.2.RC Proguard 警告

Question

使用 Android Studio:1.2.RC

我在 .gradle 中启用了混淆器:```

minifyEnabled=true


并将这些规则添加到我的 proguard-rules.pro 中:


-dontwarn com.squareup.**
-dontwarn okio.**


并将这些 lint 规则添加到我的 .gradle 文件中:


warningsAsErrors false
abortOnError false
disable 'InvalidPackage'

```

但是当我尝试在 Debug模式下运行应用程序时，我仍然收到这些警告:

```

         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)
:app:proguardDebug FAILED

```

这太奇怪了，因为我还将这些规则/选项添加到我所有依赖于 OkHttp/Picasso 的库模块中，我不知道哪里出了问题，也许这是一个 Android Studio 错误？有没有人知道这个问题的线索？

我打开了一个issue在 github 上。

您已为

禁用警告

-dontwarn com.squareup.**
-dontwarn okio.**

但是包呢(如您发布的日志中所示)

-dontwarn org.codehaus
-dontwarn java.nio

无论哪种方式，忽略警告都不是一个好方法。

尽量避免像这样缩小这些类:

-keep public class org.codehaus.**
-keep public class java.nio.**
