Solution

    subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"

    project.evaluationDependsOn(':app')

    afterEvaluate {project ->
        if (project.hasProperty("android") && project.property("android").compileSdkVersion.equals("android-R")) {
            android {
                compileSdkVersion 30
            }
        }
    }
}
