Could not initialize class org.codehaus.groovy.runtime.InvokerHelper Error

React Native için;

Change the value of "distributionUrl" to the newest gradle version in graddle.wrapper file.

To do that

go to: ..\ProjectDirectory\android\gradle\wrapper

open: gradle-wrapper.properties file for editing

go to: https://services.gradle.org/distributions/ and find out the latest version number. In my case it is 6.8

change the line: 

distributionUrl=https\://services.gradle.org/distributions/gradle-6.2-all.zip

like so

distributionUrl=https\://services.gradle.org/distributions/gradle-6.8-all.zip
