Maven丨使用Eclipse创建Maven项目时POM文件首行报错问题

在使用Eclipse创建Maven项目时，POM文件首行报错：

Could not transfer artifact org.apache.maven:maven-artifact-manager:pom:2.0.6 
from/to central (http://repo.maven.apache.org/maven2): connection timed out to 
http://repo.maven.apache.org/maven2/org/apache/maven/maven-artifact-manager/2.0.
6/maven-artifact-manager-2.0.6.pom pom.xml

解决方案如下：

1.右键项目->Run as -> Maven Clean

2.右键项目->Run as ->Maven Install

3.右键项目->Maven->Update Project

选择Force Update of snapshots/Releases

完成后，问题解决
