这是发布版本类型中的样子：

 release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        }

现在我在 proguard.txt 和 proguard.pro 中添加了一些规则，但有时它需要很长时间才能构建并且它不会发生。

我需要在哪里正确添加规则，我需要添加什么规则？

Answer 1

您可以告诉 gradle 不允许重复类（只取第一个），方法是将以下内容添加到您的 build.gradle:

jar {
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE
}

Answer 2

如果有人像我一样正在努力解决问题，请在此处找到解决方案。

将此添加到您的 proguard.pro 文件

-dontwarn org.apache.commons.**
-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.**
-dontwarn com.squareup.okhttp.**
-dontwarn okio.**
-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

Answer 3

就我而言，将此添加到构建文件后问题得到解决：

configurations {
    all {
        exclude module: 'httpclient'
    }
}

并混淆配置：

-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault
-keep class * extends com.google.api.client.json.GenericJson {
*;
}
-keep class com.google.api.services.drive.** {
*;
}
