why doesn't task wrapper function work

Question

There are many good suggestions to how to fix gradle versions, but some of them are outdated or I just couldn't find the paths that were suggested. one solution did work for me is project>project structure>project>gradle version.

Here I can change it to the supported version, and successfully builds the project.

A small error in the the javascript code, so a change is made to it. Ionic build android, now something wrong occurrs here. Minimum supprted Gradle version is 2.14.1. Current version is 2.13..

But in the project/platforms/android/build.gradle

task wrapper(type: Wrapper){ gradleVersion = '2.14.1' }

and from this link, it suggests that this is the way set your gradle wrapper.

So I am expecting in project/platforms/android/gradle/wrapper/gradle-wrapper.properties to have distributionUrl=http\://services.gradle.org/distributions/gradle-2.14.1-all.zip, instead this is what it has distributionUrl=http\://services.gradle.org/distributions/gradle-2.13-all.zip.

Can't make direct change to this file project/platforms/android/gradle/wrapper/gradle-wrapper.properties, because after each build it will revert back to gradle-2.13-all.zip.

What is going on here? can't find anything that explain why it keeps on changing the distributionUrl=http\://services.gradle.org/distributions/gradle-2.13-all.zip. Would anyone be kindly explain this please? Maybe something very stupid that I have missed. Thank you.

Update

'gradlew wrapper throws error, because certain wrapper doesn't exist under maven and the sub build.gradle uses it to download 2.14.1.prom and 2.14.1.jar. This link will explain it.

Found problem

The problem why it keeps on changing back to 2.13-all.zip is because of this line, var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-2.13-all.zip'; in the [project name]/platforms/android/cordova/lib/builders/GradleBuilder.js instead of ~/android/lib/GradleBuilder.js. (Line 164)

HERE IS A FIX :: Add this in Gradle File

task wrapper(type: Wrapper){
   gradleVersion = '7.2'
}
