Fails to compile on master branch

The latest release compiles fine, but starting from commit 056557c there are issues present:

1. "error: package org.jdesktop.beansbinding does not exist"
2. "error: package org.jdesktop.layout does not exist"

Environment:
netbeans 11.3
jdk8-openjdk 8.u242

UPDATE:
I was able to compile the game by adding following libraries into my installation of NetBeans:

1. BeansBinding, called it "beans-binding"
2. swing-layout, called it "swing-layout"
   Please note that I can't verify legitimacy of these libraries and I'm not responsible for anything bad that can happen because of using them
   The question is, it required manual intervention, thus it should probably be added into readme
