我在jenkins中面临以下错误（我正在使用cargo插件和tomcat进行集成测试）。
[2021-07-20t09:46:47.790z][error]无法在项目演示prj rest测试上执行goal org.codehaus.cargo:cargo-maven2-plugin:1.7.9:start（启动服务器）目标组织的执行启动服务器。codehaus.cargo:cargo-maven2-plugin:1.7.9:启动失败：下载失败[https://repo.maven.apache.org/maven2/org/apache/tomcat/tomcat/8.0.42/tomcat-8.0.42.zip]：java.net.connectexception:连接超时（连接超时）->[帮助1]

这在本地maven构建中非常有效，所有集成测试都在cargo tomcat中成功运行，但在jenkins构建中面临上述问题。
