maven配置总结(pom.xml和settings.xml)

一、pom.xml配置

1、自定义参数

	<properties>
       <slf4j.version>1.7.5</slf4j.version>
	   <logback.version>1.2.3</logback.version>
	</properties>

2、依赖包版本管理

<dependencyManagement>
        <dependencies>
           <dependency>
				<groupId>org.slf4j</groupId>
				<artifactId>slf4j-api</artifactId>
				<version>${slf4j.version}</version>
			</dependency>
			<dependency>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-core</artifactId>
                <version>${logback.version}</version>
            </dependency>
        </dependencies>
</dependencyManagement>

3、depoly发布路径配置

    <distributionManagement>
		<repository>
			<id>maven-releases</id>
			<url>http://xxx/maven-releases/</url>
		</repository>
		<snapshotRepository>
			<id>maven-snapshots</id>
			<url>http://xxx/repository/maven-snapshots/</url>
		</snapshotRepository>
	</distributionManagement>

4、设定远程仓库下载路径，按设定顺序依次下载

    <repositories>
        <-- 需要密码的到setting中找密码 -->
        <repository>
            <id>nexus-repos</id>
            <name>releases</name>
            <url>http://xxx/nexus/content/groups/public</url>
        </repository>  
        
        <repository>
            <id>oschina-repos</id>
            <name>Oschina Releases</name>
            <url>http://maven.oschina.net/content/groups/public</url>
        </repository>
    </repositories>
    <-- 插件下载路径 -->
   <pluginRepositories>
	    <pluginRepository>
	      <id>maven-net-cn</id>
	      <name>Maven China Mirror</name>
	      <url>http://maven.net.cn/content/groups/public/</url>
	      <releases>
	        	<enabled>true</enabled>
	      </releases>
	      <snapshots>
	        	<enabled>false</enabled>
	      </snapshots>    
	    </pluginRepository>
  </pluginRepositories>

5、环境变量配置（一般用于打包控制配置）

<profiles>
		<profile>
			<id>dev</id>
				<activation>
					<activeByDefault>true</activeByDefault>   #指定默认环境变量为dev
				</activation>
			<build>
				<resources>
					<resource>
						<directory>src/main/exchange-robot/env-dev</directory>   #指定资源文件路径
						<filtering>false</filtering>
					</resource>
				</resources>
			</build>
			<properties>  
	            <project.release.version>0.1</project.release.version>   #打包时覆盖原来的版本属性
	        </properties>
		</profile>
</profiles>

二、setting.xml配置

1、配置镜像(可以理解为代理)

  <mirrors>
    <mirror>
		<id>alimaven</id>

		<name>aliyun maven</name>

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

		<mirrorOf>central</mirrorOf> 
	    # maven中有个顶级pom指定了中央仓库为central，只需要将这个仓库镜像到阿里云即可；也可以配置 *,!maven-releases,!maven-snapshots
    </mirror>
  </mirrors>

2、配置服务密码

<servers>
	<server>
		<id>maven-releases</id>
		<username>admin</username>
		<password>xxx</password>
	</server>
	<server>
		<id>maven-snapshots</id>
		<username>admin</username>
		<password>xxx</password>
	</server>
</servers>

3、配置统一远程仓库

避免源代码中配置仓库，由于setting中不支持repositories标签，远程仓库默认需要到pom中配置。这里通过统一profils设置

<profiles>
    <profile>
      <id>dev</id>
	    <repositories>
	        <repository>
	            <id>nexus-repos</id>
	            <name>releases</name>
	            <url>http://xxx/nexus/content/groups/public</url>
	        </repository>  
	        <repository>
	            <id>oschina-repos</id>
	            <name>Oschina Releases</name>
	            <url>http://maven.oschina.net/content/groups/public</url>
	        </repository>
	    </repositories>    </profile>
  </profiles>
  <activeProfiles>
    <activeProfile>dev</activeProfile>
  </activeProfiles>
