将一个普通的java项目转换成Maven项目并不是一个很大的任务，仅仅只需要下面的几步就能将转换成功。下面我是用一个简单的Selenium测试小demon作为例子来说的。
- 移调项目中所有关联的Libraries
- 将Selenium项目转换成Maven项目
- 增加Maven依赖库到项目中
- 创建Maven的测试文件夹架构
Step1：移调项目中所有关联的Libraries
选中你需要转换的Project:Build Path > Configure Build Path
Step2： 将Selenium项目转换成Maven项目
1) 右键需转换的项目，Configure > Convert Maven Project
2) 要求填入Group ID和Artifact ID，这个不需要改变，用默认项目提供的
3) 转换成功后，该项目在Eclipse中的结构变成下面这样
没转换前的结构 转换后的结构
Step3：增加Maven依赖库到项目中
现在我们就需要将项目中所需要的依赖包加到本地中心源中，我就针对这个项目来说，我们知道我们现在缺少Selenium jar包，junit jar包等等。
1） 到 http://www.mvnrepository.com/ 上面查找Selenium
2） 点击Selenium Java
3） 选择你所需要使用的Selenium的版本
4） 关于Selenium在Maven中信息就会显示出来，然后将这些信息加到pom.xml中
5) 将Selenium的dependency的信息加到pom.xml，可以在Dependencies以流程的方式添加进去，保存，这个时候会下载相关的依赖包到本地源中心中。（需要一点时间，有任何问题，可以参考之前Maven（1）中提到，解决问题）
6）直接在pom.xml中将查询到的信息拷贝到xml文件中，保存。
7）等待依赖包被下载完后，所有的错误就会解决
Step4 创建Maven的测试文件夹架构
接下来就是检验真理的时候，看这个转换的Selenium项目能否跑起来，选择pom.xml > Run As > Maven Test 结果-----------测试用例没有被执行，这是为什么呢？仔细看看log，发现Maven默认是在\src\main\resource这个路径下找的源代码资源，测试源代码是在\src\test\resources 。
输出结果为：

那么现在的目的就是怎么自定义Maven的目录结构？
下面这个代码是把源代码设置成src目录下，把测试的源代码放在src/test下面，这样修改后就解决刚才的问题了，测试就跑起来了。这样一个Selenium项目就转换成Maven项目了。
<build>
<sourceDirectory>src/</sourceDirectory> <testSourceDirectory>src/test</testSourceDirectory>
</build>
成功后的输出结果：

WHOOOOSHHHHHHHHHHHH…………
Blimey what was that?
That was your life mate
Oh, I was not quite ready. Can I have another go?
Sorry mate, only one per person.
