detekt: Detekt 1.0.0.RC9.2 Build Fails

Hi, I am trying to setup Detekt into my new Android project, but when I run ./gradlew detektCheck I receive this message:

FAILURE: Build failed with an exception.

* What went wrong:
Task 'detektCheck' not found in root project 

The project gradle file looks like this:

buildscript {
    ext.kotlin_version = '1.2.71'
    repositories {
        google()
        jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0-alpha02'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

plugins {
    id "io.gitlab.arturbosch.detekt" version "1.0.0.RC9.2"
}

allprojects {
    repositories {
        google()
        jcenter()
        
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

apply plugin: 'io.gitlab.arturbosch.detekt'

detekt {
    input = files("$projectDir/app/src")
    parallel = false
    config = files("$projectDir/detekt.yml")
    filters = ".*test.*,.*/resources/.*"
    plugins = "$projectDir/lib/detect-custom-ruleset.jar"
    debug = true
    reports {
        xml {
            enabled = true
            destination = file("detekt/reports/detekt.xml")
        }
        html {
            enabled = true
            destination = file("detekt/reports/detekt.html")
        }
    }
}

Am I doing something wrong? Thanks!
