运行Jenkins插件的JDOM NoClassDefFoundError

Question

我正在写一个Jenkins插件，它使用我自己的一个jar。最后一个需要JDOM。因此，我的POM中有两个依赖项：

• 我自己的JAR使用JDOM
• JDOM

它成功地构建了(mvn clean install)，但是在运行过程中，我遇到了以下错误：org.jdom.JDOMException: java.lang.NoClassDefFoundError: org/jdom/Parent。

这里、这里和这里问到，没有解决方案。

JDOM确实存在于HPI at：WEB-INF\lib\jdom-1.0.jar中。我也试过和Tomcat一起跑詹金斯。并且，我试图在POM中将JDOM配置为掩码类：

<build>
  <plugins>
    <plugin>
      <groupId>org.jenkins-ci.tools</groupId>
      <artifactId>maven-hpi-plugin</artifactId>
      <version>1.94</version>
      <configuration>
        <maskClasses>org.jdom.</maskClasses> <!-- HERE -->
        <pluginFirstClassLoader>true</pluginFirstClassLoader>
      </configuration>
    </plugin>
  </plugins>
</build>

但没有成功。

我插件的pom.xml

临时解决方案：

令人惊讶的是，将JDOM jdom-1.0.jar添加到Jenkins库文件夹~\.jenkins\war\WEB-INF\lib\解决了这个问题！
