[FIXED] Failed to upgrade AGP version

Issue

I cannot update my project. When I try to do this I got this message

The Upgrade Assistant failed to upgrade this project, finding no way of performing the Upgrade AGP version from 4.1.3 to 4.2.0 command, possibly because the project's build files use features not currently supported by the Upgrade Assistant (for example: using constants defined in buildSrc, or other unrecognized constructs, in Gradle build files).

What can i do about it?

Solution

You have to manually change the gradle versions in build.gradle.kts (project) and then in gradle-wrapper.properties to version that matches your build.gradle.kts version

For example

build.gradle.kts
"com.android.tools.build:gradle:7.0.0-alpha14"

gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0-all.zip

Naturally, change the versions accordingly to what you're using
