嗯嗯，做个总结吧。问题原因：此次报错主要是因为jar包没有导入maven仓库的问题，因为公司的jar包网上maven下载不了，所以一直报那个错。解决方法：手动将jar包导入maven仓库，并将lastupdated结尾的错误文件删除。

你的maven库有问题，里面的jar包没下载成功，是以lastupdated结尾的吧？将以lastupdated结尾的jar包删了，然后重新右键项目，update project重新加载

离线了是没有小红叉了，但是还是会报错 [ERROR] Failed to execute goal on project budget: Could not resolve dependencies for project com.picc:budget:war:1.0: Failed to collect dependencies at com.essbase:japi:jar:1.1: Failed to read artifact descriptor for com.essbase:japi:jar:1.1: Could not transfer artifact com.essbase:japi:pom:1.1 from/to nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public): 这是在主机名解析时通常出现的暂时错误，它意味着本地服务器没有从权威服务器上收到响应。: Unknown host 这是在主机名解析时通常出现的暂时错误，它意味着本地服务器没有从权威服务器上收到响应。 -> [Help 1]
