听说Maven这种项目周期管理软件已经很长时间了，因为之前做的项目都不允许上网，所以没办法使用maven进行jar包下载。现在跳槽后直接使用专线链接互联网，终于有了使用maven的机会。因此就简单写一写maven的入门资料。
首先需要下载maven(因为我在windows使用eclipse进行coding，所以我下载maven的windows版本)。下载后直接安装，然后需要配置三个环境变量：
1、MAVEN_HOME=安装路径(e.g C:\apache-maven-3.0)
2、MAVEN=%MAVEN_HOME%\bin
3、在PATH变量中添加 %MAVEN_HOME%
OK。在cmd中输入 mvn -v 。如果看到
++++++++++++++++++++++++++++++++++++++++++++++++
C:\Users\Eric>mvn -version
Apache Maven 3.0.3 (r1075438; 2011-03-01 01:31:09+0800)
Maven home: D:\Program Files (x86)\apache-maven-3.0.3
Java version: 1.7.0, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.7.0\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"
++++++++++++++++++++++++++++++++++++++++++++++++
说明安装成功。
下面开始部署第一个maven project。在eclipse中新建一个maven project。
这是配置的pom.xml内容
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 3 <modelVersion>4.0.0</modelVersion> 4 5 <groupId>org.andy.maven</groupId> 6 <artifactId>MavenTest</artifactId> 7 <version>0.0.1-SNAPSHOT</version> 8 <packaging>jar</packaging> 9 10 <name>MavenTest</name> 11 <url>http://maven.apache.org</url> 12 13 <properties> 14 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 15 </properties> 16 17 <dependencies> 18 <dependency> 19 <groupId>junit</groupId> 20 <artifactId>junit</artifactId> 21 <version>3.8.1</version> 22 <scope>test</scope> 23 </dependency> 24 </dependencies> 25 </project>
我们编写一个JAVA类
1 package org.andy.maven.MavenTest; 2 3 public class MyMavenTest { 4 5 public String getString(String s){ 6 System.out.println("In the getString the para is "+s); 7 return "SUCCESS"; 8 } 9 10 public static void main(String[] args) { 11 // TODO Auto-generated method stub 12 System.out.println("In the main is OK"); 13 } 14 15 }
然后在pom.xml上面点击右键，选择run as->Maven build 。在Goals 中输入 clean compile (表示先清空，然后再重新编译).
1 [INFO] Scanning for projects... 2 [INFO] 3 [INFO] ------------------------------------------------------------------------ 4 [INFO] Building MavenTest 0.0.1-SNAPSHOT 5 [INFO] ------------------------------------------------------------------------ 6 [INFO] 7 [INFO] --- maven-clean-plugin:2.4.1:clean (default-clean) @ MavenTest --- 8 [INFO] Deleting D:\scala-workspace\MavenTest\target 9 [INFO] 10 [INFO] --- maven-resources-plugin:2.5:resources (default-resources) @ MavenTest --- 11 [debug] execute contextualize 12 [INFO] Using ‘UTF-8‘ encoding to copy filtered resources. 13 [INFO] skip non existing resourceDirectory D:\scala-workspace\MavenTest\src\main\resources 14 [INFO] 15 [INFO] --- maven-compiler-plugin:2.3.2:compile (default-compile) @ MavenTest --- 16 [INFO] Compiling 1 source file to D:\scala-workspace\MavenTest\target\classes 17 [INFO] ------------------------------------------------------------------------ 18 [INFO] BUILD SUCCESS 19 [INFO] ------------------------------------------------------------------------ 20 [INFO] Total time: 2.027s 21 [INFO] Finished at: Mon Jul 21 21:52:08 CST 2014 22 [INFO] Final Memory: 9M/23M 23 [INFO] ------------------------------------------------------------------------
18行表示maven 编译成功。
eclipse中maven命令解释：
Maven Clean -- 清空当前项目
Maven Build -- 执行maven命令
Maven Install -- 生成jar包
Update Project -- 如果修改了pom里面的依赖信息(e.g 版本号，增加/删除jar包等)，更新当前项目
