Help me deploy Angular+Spark app on heroku

How to configure Todo project (REST API with Spark) for deploying it on heroku? Trying to do it using GitHub method, server couldnt find main class. Changed gradle file many times, no success, please help. My gradle:

    group 'com.zzheads'
    version '1.0-SNAPSHOT'

    apply plugin: 'java'
    apply plugin: 'war'
    apply plugin: 'application'

    jar {
        manifest {
            attributes 'MainClass' : 'com.zzheads.App'
        }
    }

    mainClassName = "com.zzheads.App"
    sourceCompatibility = 1.8

    repositories {
        mavenCentral()
    }

    dependencies {
        compile 'org.sql2o:sql2o:1.5.4'
        compile 'com.h2database:h2:1.4.192'
        compile 'com.sparkjava:spark-core:2.3'
        compile 'com.google.code.gson:gson:2.7'

        testCompile group: 'junit', name: 'junit', version: '4.11'
    }

    task stage {
        dependsOn build
    }

Main class is com.zzheads.App i believe:

    package com.zzheads;

    import...

    public class App {

        public static final String DATASOURCE = "jdbc:h2:~/data/todos.db";
        public static final int PORT_NUMBER = 8080;

        public static void main(String[] args) {

            String datasource = DATASOURCE;
            int port = PORT_NUMBER;

            if (args.length > 0) {
                if (args.length != 2) {
                    System.out.printf("java Api <port> <datasource>%n");
                    System.exit(0);
                }
                port=Integer.parseInt(args[0]);
                datasource = args[1];
            }

            port(port);
            Sql2o sql2o = new Sql2o (String.format("%s;INIT=RUNSCRIPT from 'classpath:db/init.sql'", datasource), "", "");

... // and so on
