[1.8.9] Shading new version of netty

Hi! I have some troubles with my gradle. I installed shadow into it, and tried shading the netty package by doing:
 

dependencies {
    compile group: 'io.netty', name: 'netty-all', version: '4.1.29.Final'

}

shadowJar{
    configurations = [project.configurations.compile]
    relocate 'io.netty', 'com.hofill.netty'
}

This is the only shadow related thing I have in my build.gradle.

After I did this, I reimported the gradle packages, and then went in my code to do :

new com.hofill.netty.handler.proxy.Socks5ProxyHandler()

Which resulted in the program telling me:

• package com.hofill.netty.handler.proxy does not exist

What did I do wrong? I tried the srgExtra() but that didn't work out for me either. Could you guys please help me? Thanks a ton
