使用 jaxb api 的 java 类在 jira 中失败:Provider com.sun.xml.bind.v2.ContextFactory not found

问题描述

我正在为 Jira 编写一个涉及 XML 文档解析的插件.我正在使用 JAXB 这样做(XML 到 pojos，反之亦然)所以有一个使用 JAXB 从 pojos 生成 XML 的类.好像……

I am writing a plugin for Jira which involves parsing of XML documents. I am using JAXB to do so (XML to pojos and vice versa) So have a class which generates XML from pojos using JAXB. it looks like...

import javax.xml.bind.*;

Class Parser {
  public void m1() {
    ...
    // code which uses classes in javax.xml.bind.*
  }

  public static void main(String args[]){
   Parser p=new Parser();
   p.m1();

  } 
}

上述软件包将随 JDK 发行版 (rt.jar) 一起提供.所以我没有转播任何其他内容来运行课程.

The mentioned packages will come with JDK distribution (rt.jar). so i haven't relayed on anything else to run the class.

当我使用java"从命令行启动它时，它工作正常.但是，当我打包时将其作为 jar 并将其作为插件放入 Jira 失败并出现以下错误

when i launch it from command line using 'java' it's working properly. but, when i package it as a jar and put it as plugin in Jira it's failing with the following error

javax.xml.bind.JAXBException: Provider com.sun.xml.bind.v2.ContextFactory not found
 - with linked exception:
[java.lang.ClassNotFoundException: com.sun.xml.bind.v2.ContextFactory]
        at javax.xml.bind.ContextFinder.newInstance(ContextFinder.java:152)
        at javax.xml.bind.ContextFinder.find(ContextFinder.java:299)
        at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:372)
        at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:337)

这是在同一台机器上.我能看到的唯一区别是与从命令行启动不同，当我在 Jira 中部署它时，它不是通过实例化调用 main() 而是调用 m1().

This is on the same machine. only difference i could see is unlike launching from command line, when i deployed it in Jira, it's not calling the main() but m1() by instantiating.

我想知道发生了什么！它在同一台机器上.我不知道 Jira 是如何启动应用程序的(因为我是从命令行启动的).

I am wondering what is happening ! it's on the same machine. i do not know how Jira launches the application (as i am launching from command line).
