我配置了 jenkins，它采用 git 形式的代码并在 maven 的帮助下在 war 中进行转换。并部署在服务器上。
但是我在这个过程中遇到了一些麻烦。我能够成功构建 war，但无法使用 tomcat 管理器进行部署并出现连接超时错误。
可能的原因是什么。
这里是完整日志以了解更多信息

Build step 'Deploy war/ear to a container' marked build as failure

我经历过几次，
如果您已停止并重新启动 EC2 实例，则 tomcat 的 IP 地址已更改。您必须在 Jenkins 中以及下面的构建后操作 --> 容器 --> Tomcat --> Tomcat URL 中转到项目的“配置”设置。添加您的新 Tomcat IP 地址。
这解决了我的问题。
