Maven安装与配置，整合Eclipse

1.安装java jdk

2.下载Maven

http://maven.apache.org/download.html

安装到本机

1 将下载回来的包解压到任意地址，我的路径是D:\Program Files\apache-maven-3.0.3

2 新建环境变量M2_HOME 指向D:\Program Files\apache-maven-3.0.3

3 在path尾部添加%M2_HOME%\bin

4检查是否安装成功

打开cmd

echo %M2_HOME%

mnv –v

如下图：

插件m2eclipse的安装

下载插件eclipse-maven3-plugin,http://www.downcc.com/soft/17592.html

解压到..\MyEclipse 10\dropins

配置本地仓库

找到maven下的conf 下settings.xml 配置文件，例如：D:\Server\maven\conf\settings.xml

我们程序所需要的jar包等会先去本地仓库找，如果找不到则会去网络上的的中央仓库下载，当然默认本地仓库是放在c盘用户下.m2文件夹，这里我们可以打开.m2的settings.xml进行修改

这里我们指定本地仓库位于D盘的MavenRepository文件夹下

配置远程中央仓库

方法1：配置/conf/settings.xml

<mirrors>

<mirror>

  <id>alimaven</id>

  <name>aliyun maven</name>

  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

  <mirrorOf>central</mirrorOf>

</mirror>

<mirror>

  <id>uk</id>

  <name>Human Readable Name for this Mirror.</name>

  <url>http://uk.maven.org/maven2/</url>

  <mirrorOf>central</mirrorOf>

</mirror>

<mirror>

  <id>CN</id>

  <name>OSChina Central</name>

  <url>http://maven.oschina.net/content/groups/public/</url>

  <mirrorOf>central</mirrorOf>

</mirror>

<mirror>

  <id>nexus</id>

  <name>internal nexus repository</name>

  <url>http://repo.maven.apache.org/maven2</url>

  <mirrorOf>central</mirrorOf>

</mirror>

</mirrors>

方法2：配置项目pom.xml

<repositories>

           <repository>

                <id> alimaven</id>

                <name> aliyun maven</name>

                <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

                <releases>

                     <enabled>true</enabled>

                </releases>

                <snapshots>

                     <enabled>false</enabled>

                </snapshots>

           </repository>

</repositories>

<pluginRepositories>

           <pluginRepository>

                <id> alimaven</id>

                <name> aliyun maven</name>

                <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

                <releases>

                     <enabled>true</enabled>

                </releases>

                <snapshots>

                     <enabled>false</enabled>

                </snapshots>

           </pluginRepository>

</pluginRepositories>
