scene

When running a very old Android or Flutter project, I get the following error.

Launching lib/main.dart on SM G9209 in debug mode...
Running Gradle task 'assembleDebug'...

[!] Gradle threw an error while downloading artifacts from the network.

We only need to pay attention to the last sentence:
Gradle threw an error while downloading artifacts from the network.
According to the prompt, it is because the Android project will go to the Gradle official website to download the Gradle version specified in the gradle/wrapper directory during the construction phase.

solution

There are two methods.

Replace Gradle address (recommended)

Open gradle/wrapper/gradle-wrapper.properties in the Android project directory.
The modified distributionUrladdress is the domestic Gradle mirror address.
Tencent Cloud Gradle mirror: https://mirrors.cloud.tencent.com/gradle/ plus the version number.

#distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-all.zip
distributionUrl=https://mirrors.cloud.tencent.com/gradle/gradle-7.2-all.zip

manual download

First go to the Gradle official website to download the corresponding version of Gradle ( download address ).

Find the corresponding version and download it locally. Put it in .gradle/wrapper/dists/, and unzip it.

Recompile the project to complete.
