eclipse配置低版本maven

1、由于项目编译时报错
Unsupported major.minor version 51.0
经查是由于eclipse自带maven版本太高，不能编译旧项目

2、配置Maven3.0
Window --> Preferences --> Maven --> Installations，导入本地的Maven软件包

eclipse自带Maven插件版本是3.3.9，此次导入的是3.0.5

3、配置环境变量
1）系统变量增加：MAVEN_HOME

2）系统变量Path增加：%MAVEN_HOME%\bin

3）打开一个cmd窗口测试一下

4、settings.xml说明
1）本地库的位置
D:/repository
2）server的ID、用户名、密码
