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"类是一个注解，实际上并没有作为 joda-time-2.0.jar 中的类文件出现.有一个声明 (http://www.scala-lang.org/node/10575) 缺少注释class 文件不应该影响编译，这听起来是正确的，但我不知道这是正式声明的地方.

What is actually happening is that the missing "FromString" class is an annotation that is not actually present as a class file in joda-time-2.0.jar. There's a claim (http://www.scala-lang.org/node/10575) that a missing annotation class file is not supposed to affect compilation, which sounds correct, but I don't know where this is formally stated.

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

You'll need to add http://joda-convert.sourceforge.net/ to your project's build path.
