使用Jenkins构建项目时报了如下错误该怎么解决呢？

新手使用Jenkins构建项目时出现了如下错误，该怎么解决呢？

[ERROR] Failed to execute goal on project demo: Could not resolve dependencies for project com.example:demo:jar:0.0.1-SNAPSHOT: 
Failure to find net.sf.json-lib:json-lib:jar:2.4 in https://repo.maven.apache.org/maven2 was cached in the local repository,
 resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]

出现错误就说明你的代码的编写可能存在问题了，相关的错误信息你可以作为判断的依据啊

问题已解决，项目中有一个jar包太老了，Jenkins在下载jar包时未找到该jar包，将prom.xml中的该jar包更换掉之，Jenkins自动部署成功。

虽然您说的解决方案对我并没有什么实质性的帮助，但还是谢谢您
