maven的安装和配置

maven安装

前提：安装了jdk（本环境已经安装了jdk）

下载地址：https://maven.apache.org/download.cgi

wget https://dlcdn.apache.org/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz

解压&软连接

tar -zxvf apache-maven-3.8.6-bin.tar.gz -C /opt
ln -s apache-maven-3.8.6 mvn

配置环境变量

#vim /etc/profile
#maven
export MVN_HOME=/opt/mvn
export PATH=$MVN_HOME/bin:$PATH

#source /etc/profile

验证安装情况

[root@data3 ~]# mvn -v

maven配置

第一种方式(settings.xml文件)

在mirrors节点下加入一个新的mirror节点，配置阿里镜像地址，完整配置如下：

<mirrors>
     <!-- 阿里云仓库 -->
        <mirror>
            <id>alimaven</id>
            <mirrorOf>central</mirrorOf>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
        </mirror>
    
        <!-- 中央仓库1 -->
        <mirror>
            <id>repo1</id>
            <mirrorOf>central</mirrorOf>
            <name>Human Readable Name for this Mirror.</name>
            <url>http://repo1.maven.org/maven2/</url>
        </mirror>
    
        <!-- 中央仓库2 -->
        <mirror>
            <id>repo2</id>
            <mirrorOf>central</mirrorOf>
            <name>Human Readable Name for this Mirror.</name>
            <url>http://repo2.maven.org/maven2/</url>
        </mirror>    
</mirrors>

第二种方式(pom.xml方式)

修改项目pom.xml，在repositories节点下加入repository节点，配置阿里镜像地址，完整配置如下：

此配置参考renren-genertor项目的pom.xml配置，项目网址：https://gitee.com/renrenio/renren-generator

<repositories>
		<repository>
			<id>public</id>
			<name>aliyun nexus</name>
			<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
			<releases>
				<enabled>true</enabled>
			</releases>
		</repository>
</repositories>
	<pluginRepositories>
		<pluginRepository>
			<id>public</id>
			<name>aliyun nexus</name>
			<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
			<releases>
				<enabled>true</enabled>
			</releases>
			<snapshots>
				<enabled>false</enabled>
			</snapshots>
		</pluginRepository>
	</pluginRepositories>
