Building in windows powershell . Already tried java version 8 and gradle update

./gradlew build.gradle Support for running Gradle using Java 7 has been deprecated and is scheduled to be removed in Gradle 5.0. Please see https://docs.gradle.org/4.4/userguide/java_plugin.html#sec:java_cross_compilation for more details.

As you can see error thrown on line 10

:apply plugin'com.android.application'

gradle-wrapper.properties:-

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

Answer 1

It doesn't look like you're referencing gradle in the build.gradle file

I would expect to see the dependency listed like

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

with the appropriate gradle version
