I use Android Studio 3.6 on MacosX to develop flutter. My flutter is Flutter 1.15.17 • channel beta • https://github.com/flutter/flutter.git.

When I execute flutter run, I got these errors:

Exception: Gradle task assembleDebug failed with exit code 1`

It seems that the Gradle could not download the .jar file. But when copy the url into browser, it can be downloaded without any difficulty.

I'm not sure how to solve this problem. Who can give me some advice? Thanks.

Hi @heibor
can you please provide your flutter doctor -v and flutter run --verbose?
Also, to better address the issue, would be helpful if you could post a minimal code sample to reproduce the problem
Thank you

@TahaTesser Thank you! When I open File menu and select Invalidate Caches / Restart in Android Studio, the problem is solved.

When I upgrade my flutter to Flutter 1.17.0, the error reappears.

But when I downgrade my flutter to Flutter version 1.15.17, all things would be OK.

Could everyone who still has this problem please file a new issue with the exact descriptions
what happens, logs and the output of 'flutter doctor -v' please.
All system setups can be slightly different so it's always better to open new issues and reference
related issues.
Thank you

When I upgraded my flutter to 1.17.0. I executed flutter doctor -v, the terminal output:

Then I create a new flutter project, and execute flutter run --verbose, I have upload my log file into the gist.

Under the flutter 1.17.0-dev.3.1 in beta channel, the flutter run command will stop at the gradle error, but when I downgrade to flutter v1.15.17, all things will be well.

既然是国人，就不说蹩脚的英语了。
大兄弟，解决了么, 我也是升级到最新版本的时候报的错 。我知道这是被墙的原因 ，但是我已开了代理，亲测浏览器地址栏里可以打开 https://storage.googleapis.com/download.flutter.io/io/flutter/arm64_v8a_debug/1.0.0-4c8c31f591882b3c668992d2e9da761118899f38/arm64_v8a_debug-1.0.0-4c8c31f591882b3c668992d2e9da761118899f38.jar
但是 控制台一直报错

@shen-lan I don't think this is caused by the network. If it is a network problem, all versions shouldn't be passed!

@heibor thanks. I didn't do anything. It's works properly just now.
