运行Jenkins插件的JDOM NoClassDefFoundError

时间：2013-02-28 14:50:21

标签： java maven plugins jenkins stack-trace

我正在编写一个使用我自己的jar的Jenkins插件。最后一个需要JDOM。所以，我的POM中有2个依赖项：

  • 我自己使用JDOM的JAR
  • JDOM

它成功构建（mvn clean install），但在运行期间，我遇到了此错误：org.jdom.JDOMException: java.lang.NoClassDefFoundError: org/jdom/Parent。

在没有解决方案的情况下询问here，here和here。

JDOM jar确实出现在HPI中：WEB-INF\lib\jdom-1.0.jar。我也试过用Tomcat运行Jenkins。而且，我尝试在我的POM中将JDOM配置为mask classes：

<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>

没有成功。

我插件的pom.xml

临时解决方法：

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