MapReduce 编程 系列一 搭建基本的Maven工程

这是一个maven 工程，安装完mvn 3.2.2后， 

mvn --versionApache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-12T04:58:10+08:00)Maven home: /opt/apache-maven-3.2.3Java version: 1.7.0_09, vendor: Oracle CorporationJava home: /data/hadoop/data1/usr/local/jdk1.7.0_09/jreDefault locale: en_US, platform encoding: UTF-8OS name: "linux", version: "2.6.18-348.6.1.el5", arch: "amd64", family: "unix"

用下面的命令创建工程：

mvn archetype:generate -DgroupId=org.freebird -DartifactId=mr1_example1 -DarchetypeArtifactId=maven-archetype-quickst\art -DinteractiveMode=false

进入工程目录，打开pom.xml，修改如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>org.freebird</groupId>  <artifactId>mr1_example1</artifactId>  <packaging>jar</packaging>  <version>1.0-SNAPSHOT</version>  <name>mr1_example1</name>  <url>http://maven.apache.org</url>  <dependencies>    <dependency>      <groupId>org.apache.hadoop</groupId>      <artifactId>hadoop-core</artifactId>      <version>1.2.1</version>    </dependency>  </dependencies></project>

然后删除掉test目录

rm -rf src/test/

mvn clean compile  编译通过。
