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（堆栈跟踪已激活）：

有谁知道问题是什么？

问候

编辑：./gradlew clean assembleDebug完美运行！./gradlew clean build assembleRelease如果 runProguard 设置为关闭，则可以工作。所以这是一个 100% 的 proGuard 问题。

在过去的几个小时里，我一直在与这个问题作斗争。基本上，如果有任何警告，proguard 任务将停止执行。-d您可以通过添加到构建中来查看 Proguard 警告和堆栈跟踪（如：） gradle clean assembleRelease -d。请注意，堆栈跟踪提到“请先更正上述警告”。

为了达到构建可以通过proguard的程度，我必须将-dontwarn它抱怨的包的条目添加到我的proguard-project.txt文件中。类似于以下内容：

-dontwarn org.apache.lang.**

...ETC

所以简单地说......按照堆栈跟踪的指示去做。修复警告！:)

顺便说一句，我很抱歉，因为我现在认识到原始帖子中的堆栈跟踪与我遇到的不太一样。但是，我确实觉得我的回答很有帮助，因为显然我最终在这里试图寻找我的问题的答案。

嗯，我不明白为什么，但如果我用相同的参数（proguard ...）启动两次相同的任务，第二个似乎是好的。

但是如果第二个参数改变了，任务就会失败。

希望它会帮助某人。

您可以在 proguard-project.txt 中使用 -ignorewarnings，因此您无需指定每个包。

检查构建gradle中的 minifyEnabled 是否设置为“ false ”。因为当它是“真”时，调试器在生成签名 apk 时会出错。
