据推测，你的jar不包含清单头告诉Java将joda-time jar添加到类路径中。这是使用 java -jar 时获得其他类路径条目的唯一方法。您可以使用Ant 清单任务直接执行此操作，或者可能有多个其他方法，包括从现有的类路径构建它。

Presumably, your jar doesn't contain a manifest header telling Java to add the joda-time jar to the classpath. That's the only way to have other classpath entries when using java -jar. You could do this directly with the Ant manifest task, or there are probably multiple other ways to do it, including building it from your existing classpath.

或者，尝试

java -cp myapp.jar:joda-time-2.0.jar com.foo.YourMainClass
