    After I made the upgrade to Artic Fox, I had to set the proper SDK for gradle in settings for things to work. By default after the update, it was still using Java 1.8, although JAVA_HOME was set properly and I had issues when applying com.android.application plugin.

    Also, I removed all the JVM target params from gradle files

    The maven plugin hase been removed from Gradle 7 . Check the documentation .
    Now you should use maven-publish plugin , to activate it add

    plugins {
    id 'maven-publish'
}

    or

    apply plugin: 'maven-publish'

    in your build script, instead using apply plugin: 'com.github.dcendents.android-maven'

    Otherwise you have to roll back to older Gradle version.

    Can you switch your,

    classpath 'com.android.tools.build:gradle:7.0.0'

    to,

    classpath 'com.android.tools.build:gradle:4.2.0' // or 4.2.2

    According to Gradle Plugin Release Notes I cannot see 7.0.0 listed there.
