Question

我正在尝试使用Gradle发布我的Android应用程序。

一切正常，包括./gradlew clean build assembleRelease命令。

但是，一旦我尝试使用proguard，Gradle就无法构建发布版本。

这是我得到的错误（激活堆栈跟踪）：

有没有人知道这是什么问题？

编辑：./gradlew clean assembleDebug完美无缺！如果runProguard设置为off，则./gradlew clean build assembleRelease有效。所以这是100％的proGuard问题。

Answer 1

过去几个小时我一直在和这个问题作斗争。基本上，如果有任何警告，proguard任务将停止执行。您可以通过向构建中添加-d来查看Proguard警告和堆栈跟踪（如：gradle clean assembleRelease -d）。请注意，堆栈跟踪提到“请先纠正上述警告。”

为了达到构建通过proguard的程度，我不得不为我的-dontwarn文件中的抱怨包添加proguard-project.txt个条目。有点像：

-dontwarn org.apache.lang.**

...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，我道歉，因为我现在认识到原始帖子中的堆栈跟踪与我遇到的堆栈跟踪不完全相同。但是，我觉得我的答案很有帮助，因为显然我最终在这里试图寻找我的问题的答案。

Answer 2

嗯，我不明白为什么但是看起来如果我用相同的参数开始两次相同的任务（proguard ......），第二个是好的。

但如果第二个参数发生变化，则任务失败。

希望它会对某人有所帮助。

此致

Answer 3

您可以在proguard-project.txt中使用-ignorewarnings，因此无需指定每个软件包。

Answer 4

检查构建gradle中的 minifyEnabled 是否设置为“ false ”。因为当生成签名的apk时它将是“真正的”调试器会给出错误。

当proguard被激活时，Gradle无法构建
