我已经开始在我的项目中包含proguard。但得到的警告很少。我可以通过添加-dontwarn com.google.**来消除警告。在proguard.cfg文件中。每件事都很好，但我想从我的项目中完全消除-dontwarn命令。经过一番调查后我发现这些警告是因为我在我的图书馆项目中添加了一个jar。现在我在这里几个问题。
1）我是否需要在项目属性中添加任何内容，以便progurad能够处理我的库项目。并且也没有添加任何警告 （根据我的研究，我不需要猜测。请参阅this url）
2）由于我的 guava.jar 已添加到我的库项目中，我是否需要在我的应用程序proguard.cfg文件中添加一些命令来添加库路径，例如 -libraryjars < / strong>即可。如果是，我如何添加-libraryjars。我在谈论这个例子的路径。我应该包含哪条路径，或者在我的库项目中添加jar的路径的语法是什么？
仅仅是为了引用我正在添加错误日志。

有人可以帮助我吗？任何帮助将不胜感激。

在这种情况下，警告是无害的：缺少的类不是正确处理或执行代码所必需的。您可以将包含javax.annotation.Nullable的jar添加为项目中的依赖项，也可以禁止显示警告。这确实有效：
-dontwarn com.google.**
或者，这稍微简洁一点：
-dontwarn javax.annotation.Nullable
