谁能帮我解决这个问题？我需要发布我的应用程序。 该解决方案将不胜感激。 提前致谢。

【参考方案1】：

如果不需要缺少的类，您可以取消警告：

-dontwarn org.joda.convert.**

参见 ProGuard 手册 > 疑难解答 > Warning: can't find referenced class

【讨论】：

嗨@Eric Lafortune，我应该在哪里使用上面的代码。 project.properties 还是 proguard.cfg？

嗨@Eric Lafortune，现在我可以构建了。但它在运行应用程序时在 actionbar sherlock 中显示错误。

您好，现在我可以成功构建和运行 prj。感谢您的支持。我在我的 proguard 文件中添加了 actionbar sherlock 支持代码。

这应该是这个问题的公认答案。 @EricLafortune 为这篇简短而温馨的帖子点赞两个。

在哪里添加dontwarn 行？

【参考方案2】：

基于此处的帖子：https://plus.google.com/112998433182673852267/posts/ApBBBjv9szw

实际发生的情况是缺少的“FromString”类是一个注释，它实际上并未作为类文件存在于 joda-time-2.0.jar 中。有人声称 (http://www.scala-lang.org/node/10575) 缺少注释类文件不应该影响编译，这听起来是正确的，但我不知道这是在哪里正式声明的。

您需要将http://joda-convert.sourceforge.net/ 添加到项目的构建路径中。

【讨论】：

嗨@Morrison Chang，我添加了joda-convert-1.3.1 jar文件，仍然存在这个问题。现在警告减少了 31 个。你能帮我解决这个问题吗？

@Amarnath 如果是一个不同的问题（警告/错误），你最好用一个不同的问题。否则更新您的问题。

嗨@Morrison Chang，我在下面添加了最后的错误日志作为答案。你能帮我解决这个问题吗？

您应该将其添加为您的问题的一部分。您还同时导出 joda-time 和 joda-convert？

当我删除 joda-time jar 时，它在 DateTime 类中显示错误

【参考方案3】：

我通过将以下内容添加到我的 build.gradle > 依赖项块来修复它：

dependencies 
    implementation group: 'org.joda', name: 'joda-convert', version: '2.0.1', classifier: 'classic'
    implementation 'joda-time:joda-time:2.9.4'
