我在代码的这一行中遇到了NoSuchMethodError的问题：
private CalendarPicker<PersianCalendar> calendarPicker = CalendarPicker.persianWithSystemDefaults();
当我以intellij idea的方式运行项目时，它运行良好，但输出jar文件无法运行。
我在eclipse中导出了项目，并在eclipse中得到了这个错误。
我使用了以下库：
1-time4j-core-4.38
2-time4j-ui-5.5
3-time4j-calendar-4.38.jar
4-time4j-base-5.5.jar

Exception running application Main
最佳答案
NoSuchMethodError通常意味着您在编译时环境和运行时环境之间存在依赖关系差异。
实际上，您可能有：
1.您的类路径上的net.time4j JAR的多个不同版本
2.运行时类路径上的net.time4j JAR与编译时使用的JAR不同。
由于调用层次结构似乎暗示net.time4j本身正在调用未知的方法，因此我怀疑类路径上有多个JAR版本。
这似乎与您正在使用的JAR保持一致。您正在混合版本4.38和版本5.5。您应该坚持使用套件中所有库的一个版本，因为它们可能被设计为可以协同工作。
您可能有点困惑，因为似乎Time4J在4.x和5.x版本之间更改了包装，并且time4j-core现在可能已命名为time4j-base
似乎有一个tutorial page on the Time4J website暗示您可以简单地删除对time4-core和time4j-calendar的现有依赖关系。
