[android] How to downgrade to older version of Gradle

I have in my .gradle folder, a 2.4 folder which is the version of gradle. I want to downgrade to 2.2.1, because I need to use Gradle plugin 1.0.1. I already try to change by:

distributionUrl=https://services.gradle.org/distributions/gradle-2.2.1-all.zip

But this did not solve the issue and I'm still with 2.4 version.

How can I solve this?

I did following steps to downgrade Gradle back to the original version:

• I deleted content of '.gradle/caches' folder in user home directory (windows).
• I deleted content of '.gradle' folder in my project root.
• I checked that Gradle version is properly set in 'Project' option of 'Project Structure' in Android Studio.
• I selected 'Use default gradle wrapper' option in 'Settings' in Android Studio, just search for gradle key word to find it.

Probably last step is enough as in my case the path to the new Gradle distribution was hardcoded there under 'Gradle home' option.

Got to

gradle-wrapper.properties

Change the version of the below mentioned distribution (gradle-5.6.4-bin.zip)

distributionUrl=https://services.gradle.org/distributions/gradle-5.6.4-bin.zip

Change your gradle version in project setting: If you are using mac,click File->Project structure,then change gradle version,here:

And check your build.gradle of project,change dependency of gradle,like this:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'
    }
}

got it resolved:

uninstall the entire android studio

uninstalling android with the following commands

rm -Rf /Applications/Android\ Studio.app  
rm -Rf ~/Library/Preferences/AndroidStudio*  
rm -Rf ~/Library/Preferences/com.google.android.*  
rm -Rf ~/Library/Preferences/com.android.*  
rm -Rf ~/Library/Application\ Support/AndroidStudio*  
rm -Rf ~/Library/Logs/AndroidStudio*  
rm -Rf ~/Library/Caches/AndroidStudio*  
rm -Rf ~/.AndroidStudio*  
rm -Rf ~/.gradle  
rm -Rf ~/.android  
rm -Rf ~/Library/Android*  
rm -Rf /usr/local/var/lib/android-sdk/  
rm -Rf /Users/<username>/.tooling/gradle

Remove your project and clone it again and then goto Gradle Scripts and open gradle-wrapper.properties and change the below url which ever version you need

distributionUrl=https\://services.gradle.org/distributions/gradle-4.2-all.zip
