Gradle未下载fabric-sdk-java等依赖的问题解决请求

Hey there! Let's figure out why your Gradle dependencies aren't downloading even though the build sync completed successfully. Here are some practical steps to fix this:

• Clear your local Maven cache
  Sometimes corrupted or incomplete files in your local Maven repo (mavenLocal()) can cause Gradle to skip downloading fresh dependencies. Delete the cache directory:

  • Windows: C:\Users\<YourUsername>\.m2\repository
  • macOS/Linux: ~/.m2/repository
    Then run this command to force Gradle to refresh all dependencies:

  ./gradlew clean build --refresh-dependencies
  

• Verify Hyperledger repository configuration
  The snapshots repository you're using might have access issues, or the 1.4.x versions might have been moved to the releases repo. Try replacing your snapshots repo with the official releases repository:

  maven { url "https://nexus.hyperledger.org/content/repositories/releases/" }
  

  If you're facing network delays, you can also add a mirror repo like Alibaba's public Maven repo to speed up downloads (ensure it includes Hyperledger packages):

  maven { url "https://maven.aliyun.com/repository/public" }
  

• Check dependency version validity
  Double-check that versions like fabric-sdk-java:1.4.4 and fabric-chaincode-shim:1.4.2 actually exist in your configured repositories. A typo in the version number or a removed version could lead to Gradle silently skipping downloads. Run this command to inspect your dependency tree and see if these packages are being resolved:

  ./gradlew dependencies
  

  Look for the status of your Hyperledger dependencies—if they're marked as missing, that's a clue.

• Disable Gradle offline mode
  Accidentally enabling offline mode will prevent Gradle from fetching dependencies from remote repos. Turn it off:

  • In IntelliJ: Go to Settings → Build, Execution, Deployment → Build Tools → Gradle, uncheck "Offline work"
  • Via command line: Add the --no-offline flag when running builds:

    ./gradlew build --no-offline
    

• Clear Gradle's own cache
  Gradle's local cache can get corrupted too. Delete the cache directory:

  • Windows: C:\Users\<YourUsername>\.gradle\caches
  • macOS/Linux: ~/.gradle/caches
    Then re-sync your build.gradle file or run a build command again.

If none of these steps work, sharing the output of ./gradlew dependencies would help pinpoint the exact issue.
