How to add -Xlint:unchecked to my Android Gradle based project?

Question

I tried to add the following to the root build.gradle file:

subprojects {
    gradle.projectsEvaluated {
        tasks.withType(Compile) {

For everyone using gradle.kts use the following to match up with the simple build.gradle file

build.gradle.kts

afterEvaluate {
        tasks.withType(JavaCompile::class) {
            options.compilerArgs.add("-Xlint:unchecked")
            options.compilerArgs.add("-Xlint:deprecation")
        }
    }

build.gradle

 gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"
        }
    }
