使用JAVA工程管理越来越多的jar包,担心导错了,多导了,漏导了怎么办?
换一个IDE项目后项目会不会出一堆BUG,看的头皮发麻?
自己写的代码放在别人的机器上运行会不会出问题?
Maven的强大毋庸置疑,当使用Maven后以上这些都不是问题,但是配置maven是一件耐心的事情,基本步骤总结如下:
一、下载
http://maven.apache.org/download.cgi
也可以直接在eclipse工具中下载,点击eclipse菜单栏Help->Eclipse Marketplace搜索关键字maven到插件Maven Integration for Eclipse 并点击安装即可
架构Maven工作环境(配置环境变量)
新建:MAVEN_HOME
路径(例如):D:\360Downloads\tools\marven3.5\apache-maven-3.5.0
添加到path配置文件中:;%MAVEN_HOME%\bin;
二、配置好后验证
输入mvn -version
成功后会有如以下提示:
Microsoft Windows [版本 6.1.7601]

C:\Users\Administrator>mvn -version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:0
6+08:00)
Maven home: D:\360Downloads\tools\marven3.5\apache-maven-3.5.0-bin\apache-maven-
3.5.0\bin\..
Java version: 1.8.0_121, vendor: Oracle Corporation
Java home: D:\Program Files\Java\jdk1.8.0_121\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

三、修改默认下载地址,默认下载地址在C盘中如下:
C:\Users\Administrator\.m2
建议换一个地址,防止系统变慢,重装系统也不会影响。
如:D:\eee\1701javaee_2\maveninport_aliyun\.m2
四、将安装路径下的apache-maven-3.5.0\conf\settings.xml文件复制一份到新地址的.m2目录下面(与repository在同一目录)。
五、打开eclipse将Maven工程添加到eclipse工具中。
window->preferences->maven->installations->add->maven安装路径。
六、打开settings.xml,修改如下2个地方的内容:
1、此处为存放下载依赖存放地方,在文件第53行:

<!-- localRepository

-->
< localRepository >D:\eee\1701javaee_2\maveninport_aliyun\.m2\repository</ localRepository >
|
2、此处为修改为从阿里云服务器上下载依赖,强烈建议更换,下载速度会快很多,在文件第160行

完成后重启eclipse.
