Android Studio Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

Please make changes as per below to resolve this error.

Install Java SDK version: 14 or above.

JDK Download link: https://www.oracle.com/java/technologies/javase-jdk14-downloads.html

In gradle-wrapper.properties please use grade version 6.3 or above.

For e.g:distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip

1. This is because of the gradle version.

2. Go to: gradle/wrapper/gradle-wrapper.properties.

3. Change a version of the course by this:

distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip

The console outputs:

Welcome to Gradle 6.3!

Here are the highlights of this release:
 - Java 14 support
 - Improved error messages for unexpected failures
