Gradle 在使用 Proguard 编译发布版本时无法找到一些引用和库 类

Question

我正在尝试使用混淆器构建我的应用程序的发布版本，以便我可以缩减资源并混淆我的代码。我面临一些引用和库 类 问题，这些问题 gradle 在运行时找不到，因此给出了一些警告，如下所述。

Gradle 控制台警告

我在使用 proguard 编译以准备发布版本时遇到这些警告

我尝试了很多方法来消除这些警告，但没有找到任何有效的解决方案。我的混淆规则定义如下：

Answer 1

您收到的错误是因为缺少 类，而这些 类 不存在于 ProGuard 的输入 类 集中。

示例：jts 库使用 类 Android 中不存在的 AWT。

您将需要使用 -dontwarn 规则，而不是使用 -keep 规则（指示 ProGuard 保持现有 类 不成为 obfuscated/shrunk/optimized）。 =]

对于 jts 库：-dontwarn java.awt.** 将隐藏 AWT 警告 类

您还可以使用 -ignorewarnings 快速测试是否可以忽略所有警告并构建您的应用程序。如果之后一切正常，应该没问题。
