Speed Up Maven Dependency Downloads in IDEA with Mirror Settings

Maven Settings

By default Maven downloads dependencies from the remote central repository ( http://repo1.maven.org/maven2), which can be slow for users with poor network connections. Using a mirror such as Alibaba Cloud, NetEase, or Tencent Cloud can greatly improve download speed.

Configure the mirror by adding a <mirror> element to the settings.xml file, for example:

<mirror>
  <id>aliyunmaven</id>
  <mirrorOf>*</mirrorOf>
  <name>Alibaba Cloud Public Repository</name>
  <url>https://maven.aliyun.com/repository/public</url>
</mirror>

The settings.xml file is located at /Users/${user}/.m2/settings.xml on macOS and C:\Users\${user}\.m2\settings.xml on Windows. Copy your customized file to this location so every new Maven project uses the mirror automatically.

In IntelliJ IDEA you can also set a global Maven configuration for new projects via File | New Projects Settings | Settings/Preferences for New Projects (or File | Other Setting | Default Settings in older versions). After updating the Maven settings there and saving, all subsequently created projects will inherit the faster mirror configuration without further manual changes.
