Could not resolve all artifacts for configuration ':app:debugCompileClasspath'

Question

After the flutter 1.17 update, I tried to run my app, but it shows this error. flutter doctor command works fine. I don't understand what is happening

Launching lib\main.dart on Redmi Note 7 Pro in debug mode...

FAILURE: Build failed with an exception.

Answer 1

I met with a similar problem of unavailability of kotlin sdk resources. Couldn't find a quick solution, but the problem was most likely on the server side with resources. Because the next morning, the whole assembly was successful. Perhaps you should just wait, if before that everything was going fine and suddenly stopped.

After reading the entire branch, I still did not find a solution for my case, but it may be useful to someone. https://github.com/flutter/flutter/issues/23553

Answer 2

I had a similar issue and it was resolved when I changed the following settings in my build.gradle file:

ext.kotlin_version = '1.3.61' //from 1.3.50
dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3' //from 3.5.0
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
