1.打开idea，点击file->settings，搜索maven，然后勾上maven路径
2.复制setting.xml到上述目录，然后在mirrors结点内添加一个结点
<mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror>
下面是完整的settings.xml：
<?xml version="1.0" encoding="UTF-8"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <pluginGroups> </pluginGroups> <proxies> </proxies> <servers> </servers> <mirrors> <mirror> <id>aliyunmaven</id> <mirrorOf>central</mirrorOf> <name>aliyunCentral仓库</name> <url>https://maven.aliyun.com/repository/central</url> </mirror> <mirror> <id>repo1</id> <mirrorOf>central</mirrorOf> <name>central repo</name> <url>http://repo1.maven.org/maven2/</url> </mirror> <mirror> <id>aliyunmaven</id> <mirrorOf>apache snapshots</mirrorOf> <name>aliyunApache仓库</name> <url>https://maven.aliyun.com/repository/apache-snapshots</url> </mirror> </mirrors> <profiles> <repositories> <repository> <id>aliyunmaven</id> <name>aliyunmaven</name> <url>https://maven.aliyun.com/repository/public</url> <layout>default</layout> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> <repository> <id>MavenCentral</id> <url>http://repo1.maven.org/maven2/</url> </repository> <repository> <id>aliyunmavenApache</id> <url>https://maven.aliyun.com/repository/apache-snapshots</url> </repository> </repositories> </profiles> </settings>
