Gradle sync failed after update

Question

Android Studio asked me to upgrade the gradle to version 3.5.1, but once I do it it simply doesn't sync anymore, though I don't report any apparent bugs ...

The only error message that appears says "Gradle project sync failed. Basic functionality (eg editing, debugging) will not work properly."

22:32 Gradle sync failed: org / jetbrains / plugins / gradle / util / GradleConstants Consult IDE log for more details (Help | Show Log) (18 s 224 ms)

Already tried to clean the project, rebuild, and invalidate / restart, but nothing worked

Can someone help me?

My build script:

buildscript {
    ext.kotlin_version = '1.3.50'
    ext.anko_version='0.10.8'
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 1

try File -> Invalidate Caches/Restart

Answer 2

In my case it was caused by the Flutter Plugin. Just disable the Flutter Plugin and the sync should work again. This is the error from the logs:

Answer 3

This problem occurs when the Build Tools Version is not set for the project. You just need to set the build tools version

By opening your project structure File->Project Structure and selecting the Build Tools Version from app's property tab in Modules section.

This will add build tools version to your gradle file (Module:app) and re-sync the project.
