Making changes within pulled Kryonet into Android Studio

Engines, Libraries and Tools

Hello. If I have Kryonet pulled into my Android Studio and Gradie set like this:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile "com.esotericsoftware:kryo:3.0.1"
    compile ("com.esotericsoftware:kryonet:2.22.0-RC1") {
        exclude module : 'kryo'
    }
}

is there any chance that I can make a change within Kryonet’s files and save them?

Already tried with this, but I can’t ‘save’ the file - the changes are not working and the file is marked by dark-blue mark with ‘Changed File’.

Is there any way or I should for the real kryonet into my own repo, make changes and pull?
