IntelliJ IDEA 2017.3.5旗舰版下载依赖卡顿求助

Hey there, let's tackle that frustrating dependency download lag you're dealing with in IntelliJ IDEA 2017.3.5 Ultimate. I've got a handful of practical, tested solutions to help speed things up:

1. Switch to a Domestic Maven Mirror #

The default Maven Central Repository is hosted overseas, which is often the main culprit for slow downloads. Update your Maven settings.xml to use a local mirror like Alibaba's:

Open your Maven configuration file (usually located at {Maven_Home}/conf/settings.xml or ~/.m2/settings.xml), and add the following inside the <mirrors> section:

<mirror>
    <id>aliyunmaven</id>
    <mirrorOf>central</mirrorOf>
    <url>https://maven.aliyun.com/repository/public</url>
</mirror>

If you're using IDEA's built-in Maven, you can specify your custom settings.xml in IDEA's settings (more on that below).

2. Verify IDEA's Maven Configuration #

Double-check that IDEA is using the right Maven setup:

• Go to File > Settings > Build, Execution, Deployment > Build Tools > Maven
• Ensure Maven home directory points to your local Maven installation (not the IDEA-bundled one, which might lack custom mirror configs)
• Check the Override box next to User settings file and select your modified settings.xml
• Confirm the Local repository path is correct and you have write permissions for that folder

3. Clear Maven Cache & Force Update #

Corrupted or incomplete cached dependencies can cause hangs. Here's how to fix it:

• Navigate to your local Maven repository (default: ~/.m2/repository) and delete any folders with broken dependencies or the _remote.repositories files
• In IDEA's right-side Maven panel, click Clean followed by Install
• Alternatively, run this command in your project root to force update snapshots:

  mvn clean install -U
  

4. Adjust IDEA's Import Timeout & Memory #

Sometimes IDEA's default settings aren't enough for large dependency trees:

• Go to File > Settings > Build, Execution, Deployment > Build Tools > Maven > Importing
• Increase the VM options for importer (e.g., -Xmx1024m to give more memory to the import process)
• Raise the Timeout for downloading sources/javadoc value (try setting it to 300 seconds to avoid premature timeouts)

Your Partial pom.xml (for reference) #

<modelVersion>4.0.0</modelVersion>
