After installing Maven, I began to work at compiling the Ardublock code. I downloaded openblocks from GitHub.

Then I added the openblocks-master to the same folder that apache-maven-3.6.1 was in. I then installed it and compiled it with maven. Then I was finally able to compile the Ardublock code. 

Once the Ardublock code was compiled, I was able to execute it from my terminal so that a window opened up. I then looked through the main source code, but realized that every time I made a change, I had to close the current window before recompiling and executing, otherwise execution issues would occur. 

I made a simple block and added it to one of the existing drawers. I also changed a few of the block names as well.
