解决方案
请注意以下操作可能会因版本差异而有所不同，请做好备份工作。
方案1
检查并修复配置文件的语法错误
1. 停止 Jenkins 服务：
shell
service jenkins stop
2. 将 JENKINS_HOME/config.xml 文件备份：
shell
mv JENKINS_HOME/config.xml JENKINS_HOME/config.xml_bak
3. 启动 Jenkins 服务：
shell
service jenkins start
方案2
使用 XML 校验工具检查 XML 标签的平衡性
1. 使用第三方的 XML 校验工具来检查配置文件 config.xml 是否有未平衡的 XML 标签。
2. 根据校验结果修复配置文件中的 XML 标签错误。
以上两种方案中，方案1适
