这是我收到的例外情况:

Answer 1

尝试将此代码添加到您的proGuard规则中,它对我有用

-ignorewarnings
-keep class * {
    public private *;
}

答案发布在这里: 任务'执行失败':app:transformClassesAndResourcesWithProguardForRelease

Answer 2

将此代码添加到 ..your-project/app/proguard-rules.pro

 -ignorewarnings

你的签名apk将成功生成...

更新:

这是更好地使用你的警告信息来修复-dontwarn或-keep 上的按键你proguard-rules.pro......因为如果你使用(也许你的库)Java反射在你的代码的应用程序将崩溃......

Answer 3

它对我有用我还必须在pro-gaurd.txt文件中添加以下内容

#### -- Picasso --
 -dontwarn com.squareup.picasso.**

 #### -- OkHttp --

 -dontwarn com.squareup.okhttp.internal.**

 #### -- Apache Commons --

 -dontwarn org.apache.commons.logging.**

     -ignorewarnings 
-keep class * {
public private protected *;
}

Answer 4

我什么都没改变只是评论

// shrinkResources true
// minifyEnabled true

您不想更改浪费了2天后我已经搜索过的所有proguard文件
