Ionic cordova build failed with errors

ionic-v1
1

I am having issues building and running ionic app. When I try to ionic cordova build android the error wll show:
ll

In my GraddleBuilder.js:

 var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'https\\://services.gradle.org/distributions/gradle-4.1-all.zip';

In my graddle-wrapper.properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=../gradle-3.3-all.zip

Everytime I change my graddle-wrapper.properties to ../gradlle-4.1-all.zip it will change back to ../gradlle-3.3-all.zip after executing build or run command. Please help.
