ProGuard 警告不允许我的应用编译发布

【中文标题】ProGuard 警告不允许我的应用编译发布

【英文标题】：ProGuard warning doesn't let my app compile for release

【发布时间】：2016-10-05 19:22:51

【问题描述】：

当我尝试通过 android Studio 正常构建我的项目时，我的应用编译得很好，生成调试 apk 和 mapping.txt 没有问题。但是一旦我尝试使用以下命令行构建一个版本：

./gradlew assembleRelease

我收到一条警告，目前我无法修复。

这是我的堆栈跟踪：

这是我的 proguard-rules.pro

-dontwarn com.crittercism.**
-keep public class com.crittercism.**
-keepclassmembers public class com.crittercism.**

    *;

-keepattributes SourceFile, LineNumberTable

有什么想法吗？

我已经搜索了整个 ***，但没有其他问题对我的问题有帮助

异常告诉它：请先纠正上述警告。 ProGuard 需要在继续之前修复其所有警告。请发布包含 ProGuard 警告的部分输出。异常本身并没有多大帮助。

我只有一个警告，唯一相关的信息是proguard提供的链接：proguard.sourceforge.net/manual/…

【参考方案1】：

您可以使用以下选项忽略警告：

-ignorewarnings

在 ProGuard 执行期间仍会打印警告，但它会让您的构建继续进行。

无论如何，如果可能，建议在任何情况下修复警告。

【讨论】：

我赞成你的回答，因为我只有一个警告，这个解决方案实际上适合我的问题（特别是对一件事进行警告或只使用这条线不会有太大的不同）。但由于这不是一个好的解决方案，我不会将其标记为正确。希望你能理解。感谢您的关心

您需要包含您收到的实际警告，以便我们可以建议适当的规则来忽略/修复它们。 -ignorewarnings 标志只允许您运行 ProGuard，这在大多数情况下是可以的（特别是如果您不启用优化）。

但正如我所说，如果我只收到一个警告，真的没有什么不同吧？

好吧，即使您只有一个警告，也最好知道它是什么。您的回答也很奇怪：您不想添加 -dontwarn 但抱怨 -ignorewarnings 不是一个好的解决方案。没有其他解决方案：选择两者中的任何一个。

【参考方案2】：

您没有包含特定的 ProGuard 警告，因此我只能尝试以一般方式提供帮助。

根据官方 Proguard 文档：

如果您不想过滤掉有问题的类，可以使用 -ignorewarnings 选项，甚至 -dontwarn 选项试试运气。仅当您确实知道自己在做什么时才使用这些选项。

...

例如，如果 ProGuard 抱怨它找不到 java.awt 类，那么您正在使用的某个库引用了 java.awt。这有点阴暗，因为 Android 根本没有这个包，但如果你的应用程序仍然可以工作，你可以让 ProGuard 接受它，例如使用“-dontwarn java.awt.**”。

即使在您的情况下您确定可以忽略所有警告，也不要使用-ignorewarnings，因为它甚至会掩盖未来可能被忽视的警告。为您知道可以安全忽略的每个案例单独添加 -dontwarn（例如 -dontwarn java.awt.**），并在更新应用代码库时始终检查您的 ProGuard 配置。

【讨论】：

-ignorewarnings 只会让您的构建继续，在 ProGuard 执行期间仍会打印特定警告。此设置是 DexGuard（ProGuard 的商业版本）的默认设置。

@tome 感谢您的更正。我编辑了我的答案。最后，我更喜欢 dontwarn 进行控制和双重检查。
