Updating Gradle from version 4.2.0 to 7.0.2. ended up in an error during minifying with R8. (Using Java 1.8)
Unfortunately, the error message is not very telling (see below).

I am using android sdk 29.
I fixed it by downloading and using the Android SDK 28.
I have been coding kotlin in intellij to develop an app for android but then found out about flutter and wanted to give it a try. Installed flutter sdk and flutter and dart plugins ok. Now even the default empty demo project runs in both my phone and in emulator but i can't build it and cannot generate an apk. I have also downloaded the android studio to try with it but a similar error occurs in it too.
Searched all the web for a solution.

2018-02-04 14:53:15,234 [ thread 15] INFO - e.project.sync.GradleSyncState - Gradle sync failed (4s 121ms)
Using Invalidate Caches/Restart and removing the .gradle folder did not help. Why is this? How is it fixed?
After unsetting a local gradle distribution in Settings > Build, Execution, Deployment > Gradle (which was set for debugging this problem), Android Studio offered to update to gradle:3.0.1 from gradle:3.0.0. This fixed it.
Previous steps taken:
add the google() repository to buildscript and allprojects
upgrade the compileSdkVersion, and targetSdkVersion to 27
upgrade all com.android.support libraries to 26.1.0
I was getting similar errors after I upgraded my Android Studio to 3.1.3. I don't remember the exact version I was on before that -- version 2 series.
The reason I was getting these errors was because the Gradle plugin version I was using was too low.
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
...
}
Once I updated the version from 2.2.3 to 2.3.3, then Android Studio was able to move on and give me more meaningful error messages such as
Gradle sync failed: Minimum supported Gradle version is 3.3. Current version is 2.14.1. If using the gradle wrapper, try editing the distributionUrl in gradle/wrapper/gradle-wrapper.properties to gradle-3.3-all.zip
From there, it's just a matter of resolving version compatibility issues.
For me, it was a simple solution: I had deleted a module from my project and forgot to delete it from settings.gradle
Maybe this can help somebody
I'm using gradle and intellij to build my android project. My generated java files are stored in the .aagen directory. I can import all these generated classes in my non generated classes. Still when I build my project with my build.gradle script this is the output.
/android/source/com/app/App.java:30: cannot find symbol
symbol : class TestActivity_
location: package com.ui
import com.ui.TestActivity_;
This is my error I got:
