BUILD FAILED in 2s Exception: Gradle task assembleDebug failed with exit code 1

I already change JDK 16 to 8 and update Gradle version.

Solution 1:^[1]

I added this line to ./android/gradle.properties for OSX org.gradle.java.home=/Applications/Android Studio.app/Contents/jre/Contents/Home Android Studio changed their file path for the jre so I think this will go away once flutter fixes with a new version

Solution 2:^[2]

In gradle.properties, try to add that org.gradle.java.home=C:\\Program Files\\Android\\Android Studio\\jre

Solution 3:^[3]

I added this line to ./android/gradle.properties for OSX:

org.gradle.java.home=/Applications/Android Studio.app/Contents/jre/Contents/Home

This is what worked for me.

To resolve this issue you have to follow these steps, they worked for me:

Go to your gradle-wrapper.properties file and change the gradle plug-in version to the latest. e.g distributionUrl=https://services.gradle.org/distributions/gradle-7.2-bin.zip

It means 7.2 is the latest as at the time of writing this.

NOTE: Open your flutter app: android>gradle>wrapper>gradle-wrapper.properties

Then, open your app and go to: android>build.gradle

open the file and in the buildScript and under the dependencies block, give a compactible version to the Gradle.

An example is shown below.

buildscript {
  ext.kotlin_version = '1.6.21'
  repositories {
      google()
      mavenCentral()
  }

  dependencies {
      classpath 'com.android.tools.build:gradle:7.1.3'
  }
}

In your manifest file: android>app>src>main>androidManifest.xml

open it and under the activity tag, add: android:exported="true"

You can then invalidate caches and rebuild your project. try it and give me feedback.
