Note about challenge - room.schemaLocation

The some/path/goes/here/ value provided to the build.gradle file

kapt {
    arguments {
        arg("room.schemaLocation", "some/path/goes/here/")
    }
}

is a path relative to the app/build.gradle file in your project structure. From reading elsewhere, a good practice is to set this path to be

kapt {
    arguments {
        arg("room.schemaLocation", "$projectDir/schemas/")
    }
}

which then places a json file inside of app/schemas/.
