Windows更新后Android Studio Gradle同步失败：Read timed out 求助

Hey there, sorry to hear you're stuck with this Gradle sync timeout issue post-Windows 10 update—this is a common hiccup after system updates, and we can work through it step by step. Here are the most effective fixes to try:

1. Switch to a Domestic Maven Mirror (Network Dependency Fix) #

More often than not, the timeout happens because Gradle's default repositories are slow to access from your network. Replace the default repos with a faster domestic mirror in your project's root build.gradle file:

buildscript {
    repositories {
        // Replace default repos with these
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
    }
    // ... rest of your buildscript code
}

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
    }
}

After making changes, click Sync Now and see if the timeout goes away.

2. Increase Gradle Sync Timeout Limits #

Windows updates might have tweaked system resource allocations, causing Gradle to hit its timeout threshold too soon. You can extend this in two ways:

• Via IDE Settings: Go to File > Settings > Build, Execution, Deployment > Build Tools > Gradle. Under Gradle VM options, add -Dorg.gradle.timeout=300 (sets timeout to 5 minutes).
• Via gradle.properties: Open your project's gradle.properties file and add these lines:

  org.gradle.jvmargs=-Xmx2048m -Dorg.gradle.timeout=300
  org.gradle.parallel=true
  

3. Clear Corrupted Gradle Cache #

System updates sometimes mess with cached Gradle files. Delete the cache folder to force a fresh download:

• Navigate to C:\Users\<Your Username>\.gradle\caches
• Delete all contents inside this folder (don't worry, Gradle will rebuild it)
• Restart Android Studio and trigger a sync again

4. Check Windows Firewall/Antivirus Restrictions #

Windows 10 updates often reset firewall or antivirus rules, blocking Android Studio from accessing the internet.

• Open Windows Defender Firewall > Allow an app or feature through Windows Defender Firewall
• Find Android Studio in the list, make sure both Private and Public boxes are checked
• If it's not listed, click Change settings > Allow another app and browse to your Android Studio executable (usually in C:\Program Files\Android\Android Studio\bin\studio64.exe)
• Temporarily disable your antivirus software and test the sync—if it works, add AS to your antivirus whitelist

5. Update Gradle and Android Gradle Plugin #

Outdated Gradle versions might conflict with the updated Windows environment.

• Update Gradle Wrapper: Open gradle/wrapper/gradle-wrapper.properties and update the distributionUrl to the latest stable version (e.g., https\://services.gradle.org/distributions/gradle-8.4-all.zip)
• Update Android Gradle Plugin: In your project's root build.gradle, update the com.android.tools.build:gradle dependency to match the Gradle version (check the official compatibility table if unsure)

6. Reset Android Studio to Default Settings #

If none of the above works, a corrupted IDE setting from the Windows update might be the culprit:

• Go to File > Manage IDE Settings > Restore Default Settings
• Confirm the reset, restart Android Studio, then re-import your project and sync

Give these steps a try one by one—most users fix this issue with the first three steps. Good luck!
