new JedisPool is getting a NoClassDefFoundError

Question

I'm going to create a Jedis pool, (in a really simple way)

but I got this error below:

    public static void main(String[] args) {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxTotal(10);
        new JedisPool(jedisPoolConfig, "localhost");
    }

Jedis has slf4j-api as a compile dependency, you need to add slf4j-api jar to your application
