How Do I Fix "unexpected element found in "?

Tried to change build.gradle

    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
    }

and gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

but after build gradle-wrapper.properties rollbacked

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.3-all.zip

and in the log:

Minimum supported Gradle version is 6.1.1. Current version is 4.10.3. If using the gradle wrapper, try editing the distributionUrl in C:\projects\mgdlab\ionic\paddleapp-app\gradle\wrapper\gradle-wrapper.properties to gradle-6.1.1-all.zip

Help me please
