今天，嗯，博客开通第二天， 项目的第一天，今天只是理了一下思路，扒了扒模板，就简单分享一下今天我所犯得一个错误以及maven的基本使用方法！
如今我们构建一个项目需要用到很多第三方的类库，如写一个使用spring的Web项目就需要引入大量的jar包。一个项目Jar包的数量之多往往让我们瞠目结舌，并且Jar包之间的关系错综复杂，一个Jar包往往又会引用其他Jar包，缺少任何一个Jar包都会导致项目编译失败。
以往开发项目时，程序员往往需要花较多的精力在引用Jar包搭建项目环境上，而这一项工作尤为艰难，少一个Jar包、多一个Jar包往往会报一些让人摸不着头脑的异常。
而Maven就是一款帮助程序员构建项目的工具，我们只需要告诉Maven需要哪些Jar 包，它会帮助我们下载所有的Jar，极大提升开发效率。
前面安装什么的我就不多说，有需要私我就行，安装完后去测试命令（CMD）,测试一下看是否 安装成功，
C:\Users\Administrator>mvn -version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: D:\apache-maven-3.3.9-bin\apache-maven-3.3.9\bin\..
Java version: 1.7.0_15, vendor: Oracle Corporation
Java home: D:\Program Files (x86)\Java\jdk1.7.0_15\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 8", version: "6.2", arch: "x86", family: "windows"
出现以上代码，那就说明安装成功了，没有的话，再去检查一下环境变量。
接下来就是去创建项目
这里我们去other里面，输入maven,选择创建maven porject
继续下一步，选择web 里的最后一个
继续下一步，我们在里面输入自己的工程名，包名就好了
建成之后是这样的，
当然里面是没有jar包的，现在我们只需要在pom.xml里面去配置一些东西，做项目的时候jar包就不用引了
这里我帮大家 把一些常用的先粘贴下来，有其他需要的可以去http://mvnrepository.com/这个网址去寻找
你所需要的jar包。
