当proguard被激活时，Gradle失败
我想用Gradle发布我的Android应用程序。
一切正常，包括./gradlew clean build assembleRelease命令。
但是，只要我尝试使用proguard，Gradle无法构build发行版本。
这是我得到的错误（堆栈跟踪激活）：

有没有人有什么问题的想法？
问候
编辑： ./gradlew clean assembleDebug完美的作品！ 和./gradlew clean build assembleRelease如果runProguard设置为closures。 所以这是一个100％的proGuard问题。
过去几个小时我一直在和这个问题斗争。 如果有任何警告，基本上proguard任务将停止执行。 您可以通过在构build中添加-d （如： gradle clean assembleRelease -d ）来看到Proguard警告和gradle clean assembleRelease -d 。 请注意，堆栈跟踪提到“请首先更正上述警告”。
为了达到构build可以通过proguard的点，我不得不添加-dontwarn条目，它抱怨我的proguard-project.txt文件的包。 有些东西是：
-dontwarn org.apache.lang.**
…等等
所以，简单地说，就像stacktrace指示你做的那样。 修复警告！ 🙂
顺便说一句，我很抱歉，因为我现在认识到，在原来的poststacktrace是不完全相同的，我遇到。 不过，我确实感到我的答案是有帮助的，很显然我最终在这里试图寻找我的问题的答案。
嗯，我不明白为什么，但似乎如果我开始两次相同的任务相同的参数（proguard …），第二个是好的。
但是如果第二个参数改变，任务就会失败。
希望它能帮助别人。

检查您的build build gradle中的minifyEnabled是否设置为“ false ”。 因为当生成已签名的apk的时候它将会是“真正的”debugging器会给出一个错误。
