一、镜像问题
1、为什么需要配置maven国内镜像?
- 在不配置镜像的情况下,maven默认会使用中央库.--https://repo.maven.apache.org/maven2
- maven中央库在国外,有时候访问会很慢,尤其是下载较大的依赖的时候,有时候速度会很慢,甚至会出现无法下载的情况。
- 为了解决依赖下载速度的问题,需要配置maven国内镜像。
2、配置国内maven镜像(阿里云镜像)
<mirrors> <!-- mirror | Specifies a repository mirror site to use instead of a given repository. The repository that | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. | --> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors>
3、OSC MAVEN仓库目前已停止提供服务。
以下地址已访问不了:
http://maven.oschina.net/content/groups/public
http://maven.oschina.net/content/repositories/thirdparty/
<?xml version="1.0"?> <settings> <localRepository>D: epository</localRepository><!--需要改成自己的maven的本地仓库地址--> <mirrors> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> <profiles> <profile> <id>nexus</id> <repositories> <repository> <id>nexus</id> <name>local private nexus</name> <url>http://maven.oschina.net/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>nexus</id> <name>local private nexus</name> <url>http://maven.oschina.net/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile></profiles> </settings>
