如何从NoSuchMethodError库修复Time4J？

Question

我在代码的这一行中使用了NoSuchMethodError：

    private CalendarPicker<PersianCalendar> calendarPicker = CalendarPicker.persianWithSystemDefaults();

当我在intellij中运行该项目时，它运行得很好，但是输出jar文件不会运行。我在eclipse中导出了这个项目，并在eclipse中得到了这个错误。

我用过这个图书馆：

1-Time4j-核心-4.38

2- time4j-ui-5.5

3-Time4j-日历-4.38.jar

4-Time4j-基本-5.5jar

Exception running application Main

Answer 1

NoSuchMethodError通常意味着编译时和运行时环境之间存在依赖关系。

实际上，您可能在类路径上有以下两个版本: 1. net.time4j JAR的多个不同版本；2.运行时类路径上的不同net.time4j JAR，与编译期间使用的不同。

由于调用层次结构似乎表明net.time4j本身正在调用它不知道的方法，因此我怀疑类路径上有多个JAR版本。

这似乎与你所说的罐子是一致的。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，因为它们很可能是一起设计的。

您可能有点困惑，因为Time4J似乎在4.x和5.x版本之间更改了打包，而time4j-core现在可能被命名为time4j-base

有一个Time4J网站上的教程页面，它似乎表明您可以简单地删除对time4-core和time4j-calendar的现有依赖。

Answer 2

我也有过同样的问题，不同的time4j版本混合在一起，因为在网上找到了不同的来源。

因此，这就是导致问题的不工作的POM.XML配置：

<!-- https://mvnrepository.com/artifact/net.time4j/time4j-core -->
       <dependency>
          <groupId>net.time4j</groupId>
          <artifactId>time4j-parent</artifactId>
          <version>5.5</version>
          <type>pom</type>
      </dependency>
        <dependency>
           <groupId>net.time4j</groupId>
           <artifactId>time4j-core</artifactId>
           <version>4.38</version>
       </dependency>      
<!-- https://mvnrepository.com/artifact/net.time4j/time4j-base -->
       <dependency>
           <groupId>net.time4j</groupId>
           <artifactId>time4j-base</artifactId>
           <version>5.5</version>
       </dependency>
       <dependency>
           <groupId>net.time4j</groupId>
           <artifactId>time4j-i18n</artifactId>
           <version>4.38</version>
       </dependency>
    </dependencies>

解决方案:更新。Maven仍然在使用4.38，虽然我已经更改为5.5 -清理(清除)存储库是必要的。

<!-- https://mvnrepository.com/artifact/net.time4j/time4j-base -->
       <dependency>
           <groupId>net.time4j</groupId>

现在它就像一种魅力。
