Note: there were 4 references to unknown classes.
You should check your configuration for typos.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
Note: there were 16 unkept descriptor classes in kept class members.
You should consider explicitly keeping the mentioned classes
(using '-keep').
(http://proguard.sourceforge.net/manual/troubleshooting.html#descriptorclass)
Note: there were 17 unresolved dynamic references to classes or interfaces.
You should check if you need to specify additional program jars.
(http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
Warning: there were 126 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
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)
Warning: there were 33 instances of library classes depending on program classes.
You must avoid such dependencies, since the program classes will
be processed, while the library classes will remain unchanged.

:app:transformClassesAndResourcesWithProguardForFreeRelease FAILED
这就是发布版本类型：

现在我在proguard.txt和proguard.pro中添加了一些规则，但有时需要很长时间才能构建并且不会发生。
我需要在哪里正确添加规则以及需要添加的规则是什么？

您可以通过将以下内容添加到build.gradle来告诉gradle不允许重复的类（仅采用第一个类）：
jar {
duplicatesStrategy = DuplicatesStrategy.EXCLUDE
}
答案 1 :(得分：1)
如果有人像我一样努力让它发挥作用，那么就找到解决方案。
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>;
}
答案 2 :(得分：0)
就我而言，将其添加到构建文件后，问题得以解决：
configurations {
all {
exclude module: 'httpclient'
}
}
并保护配置：
-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault
-keep class * extends com.google.api.client.json.GenericJson {
*;
}
-keep class com.google.api.services.drive.** {
*;
}
