这里不再说么maven的安装和环境变量配置
Maven基本命令及使用
前往项目pom.xml所在目录，或者直接使用Eclipse的m2e插件来操作。
mvn clean 清除上次打包的内容，在项目的target目录下
mvn test 测试，结合单元测试使用
mvn compile 编译，如果缺包，可以促使项目自己去下载引用包
mvn install 把项目安装到本地仓库，供其他项目试验
mvn package 打包，这里指打出jar包
mvn deploy 部署，将自己开发的项目打包部署到中央服务器，供其他人使用
mvn assembly:assembly 用插件归档打包
maven的setting.xml配置
<?xml version="1.0" encoding="UTF-8"?>

| This is the configuration file for Maven. It can be specified at two levels:
|
| 1. User Level. This settings.xml file provides configuration for a single user,
| and is normally provided in ${user.home}/.m2/settings.xml.
|
| NOTE: This location can be overridden with the CLI option:
|
| -s /path/to/user/settings.xml
|
| 2. Global Level. This settings.xml file provides configuration for all Maven
| users on a machine (assuming they're all using the same Maven
| installation). It's normally provided in
| ${maven.home}/conf/settings.xml.
|
| NOTE: This location can be overridden with the CLI option:
|
| -gs /path/to/global/settings.xml
|
| The sections in this sample file are intended to give you a running start at
| getting the most out of your Maven installation. Where appropriate, the default
| values (values used when the setting is not specified) are provided.
|

<!-- localRepository
| The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
-->
<!--本地仓库。该值表示构建系统本地仓库的路径。其默认值为~/.m2/repository。 -->
<localRepository>F:\coding\apache-maven-3.2.5\.m2\repository</localRepository>
<!-- interactiveMode
| This will determine whether maven prompts you when it needs input. If set to false,

| the parameter in question.

<!-- offline
| Determines whether maven should attempt to connect to the network when executing a build.

<!-- pluginGroups
| This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.

| "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.

<!-- pluginGroup
| Specifies a further group identifier to use for plugin lookup.

<!-- proxies
| This is a list of proxies which can be used on this machine to connect to the network.
| Unless otherwise specified (by system property or command-line switch), the first proxy
| specification in this list marked as active will be used.

<!--配置服务端的一些设置。一些设置如安全证书不应该和pom.xml一起分发。这种类型的信息应该存在于构建服务器上的settings.xml文件中。-->

<!-- server
| Specifies the authentication information to use when connecting to a particular server, identified by

<!-- mirrors
| This is a list of mirrors to be used in downloading artifacts from remote repositories.
|
| It works like this: a POM may declare a repository to use in resolving certain artifacts.
| However, this repository may have problems with heavy traffic at times, so people have mirrored
| it to several places.
|
| That repository definition will have a unique id, so we can create a mirror reference for that
| repository, to be used as an alternate download site. The mirror site will be the preferred
| server for that repository.

<mirrors>
<!--给定仓库的下载镜像。 -->
<mirror>
<!--该镜像的唯一标识符。id用来区分不同的mirror元素。 -->
<id>nexus</id>
<!--该镜像的URL。构建系统会优先考虑使用该URL，而非使用默认的服务器URL。 -->
<url>http://192.168.1.201:8081/nexus/content/groups/public/</url>
<!-- 这里只有配置正确，镜像才会同步远程jar包。-->
<!-- 被镜像的服务器的id。例如，如果我们要设置了一个Maven中央仓库（http://repo1.maven.org/maven2）的镜像，就需要将该元素设置成central。这必须和中央仓库的id central完全一致。-->
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
<!-- profiles
| This is a list of profiles which can be activated in a variety of ways, and which can modify
| the build process. Profiles provided in the settings.xml are intended to provide local machine-
| specific paths and repository locations which allow the build to work in the local environment.
|
| For example, if you have an integration testing plugin - like cactus - that needs to know where
| your Tomcat instance is installed, you can provide a variable here such that the variable is
| dereferenced during the build process to configure the cactus plugin.
|
| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
| section of this document (settings.xml) - will be discussed later. Another way essentially
| relies on the detection of a system property, either matching a particular value for the property,
| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
| value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
| Finally, the list of active profiles can be specified directly from the command line.
|
| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
| repositories, plugin repositories, and free-form properties to be used as configuration
| variables for plugins in the POM.

maven的test，这里对应好路径，方法命名规则，能自动测试。
假设业务代码如下
package com.hiekn.test;
public class HelloWorld {
public static void main(String args[]){
HelloWorld h = new HelloWorld();
System.out.print(h.say());
}
public String say(){
return "hello world";
}
}
对应测试代码
package com.hiekn.test;
import static org.junit.Assert.*;
import org.junit.Test;
public class HelloWorldTest{
@Test
public void testSay(){
HelloWorld h = new HelloWorld();
String s = h.say();
assertEquals("hello world",s);
}
}
下面是测试的一个比较全的pom.xml供参考
