Question

我正在尝试使用maven shade插件。

我正在使用：Java 7，Spring 4.1.6.RELEASE，Hibernate 4.3.9Final，maven-shade插件版本2.3

我有以下错误。无法弄清楚问题。

修改：发现问题，但仍然没有解决方案：我正在使用org.threeten.threetenbp中的LocalDate，我已经设置了jadira.usertype.autoRegisterUserTypes = true。正如我所说，从IntelliJ运行主类时工作正常，但在执行jar时却没有。

Answer 1

Java8中出现了

java.time.LocalTime ，因此您所依赖的某些库可能正在使用Java8的类（根据您的堆栈跟踪，这是Hibernate）

Answer 2

您对Java {8>中引入的java.lang.LocalTime具有依赖性。

由于您使用的是Java 7，因此获得ClassNotFoundException。切换到Java 8或替换引入依赖项的库。

Maven shade插件ClassNotFoundException
