maven学习九之pom.xml或settings.xml对nexus的配置

(1)在POM中配置Nexus仓库

<project>
...
<repositories>
<repository>
<id>nexus</id>
<name>Nexus</name>
<url>http://localhost:8081/nexus/content/groups/public/<url>
<release><enabled>true</enabled></release>
<snapshots><enabled>true></enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>nexus</id>
<name>Nexus</name>
<url>http://localhost:8081/nexus/content/groups/public/<url>
<release><enabled>true</enabled></release>
<snapshots><enabled>true></enabled></snapshots>
</pluginRepository>
</pluginRepositories>
...
</project>

上述配置只对当前项目有效，若需让本机所有Maven项目均使用Mavne私服，应该在setting.xml中进行配置。

(2)在setting.xml中配置Nexus仓库

<settings>
...
<profiles>
<profile>
<id>nexus</id>
<repositories>
<repository>
<id>nexus</id>
<name>Nexus</name>
<url>http://localhost:8081/nexus/content/groups/public/<url>
<release><enabled>true</enabled></release>
<snapshots><enabled>true></enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>nexus</id>
<name>Nexus</name>
<url>http://localhost:8081/nexus/content/groups/public/<url>
<release><enabled>true</enabled></release>
<snapshots><enabled>true></enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>nexus</activeProfiles>
</activaProfiles>
...
</settings>

activeProfiles用来激活私服

(3) 配置镜像让Maven只使用私服

<settings>
...
<mirrors>
<mirror>
<id>nexus</id>
<mirrorOf>*<?mirrorOf>
<url>http://localhost:8081/nexus/content/groups/public/</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<repositories>
<repository>
<id>central</id>
<name>http://central</name>
<release><enabled>true</enabled></release>
<snapshots><enabled>true></enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<name>http://central</name>
<release><enabled>true</enabled></release>
<snapshots><enabled>true></enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>nexus</activeProfiles>
</activaProfiles>
...
</settings>

只要mirrorOf中的工厂需要下载jar，都会自动来找该镜像。如果镜像地址有，就下载下来。若镜像地址没有，mirrorOf中的工厂也不会到中央资源库下载，而是由镜像去下载。这是推荐的做法。若镜像下载不到，就下载失败。
