unable to resolve class task

[alexei-28]

In build.gradle:

plugins {
    // Apply the application plugin to add support for building a CLI application in Java.
    id 'application'
    // Build uber-jar
    id 'com.github.johnrengelman.shadow' version '7.1.2' apply false
    id "com.nocwriter.runsql" version "1.0.3"
}

task<RunSQL>("createEmptyDB") {
    config {
        username = ""
        password = ""
        url = "jdbc:sqlite://c:\\dev\\temp\\myproject\\app\\data\\my.db"
        driverClassName = "org.sqlite.JDBC"
        scriptFile = arrayOf("/db/sqlite/create-tables.sql", "/db/sqlite/insert-tables.sql")
    }
}

But when I run:

gradle createEmptyDB

I get error:

What went wrong:
Could not compile build file 'C:\dev\temp\myproj\app\build.gradle'.

  build file 'C:\dev\temp\myproj\app\build.gradle': 121: unable to resolve class task
