• First of all, add it to your .gitignore file and don't forget to commit the file :-)

• You can use this site: http://gtiignore.io to generate the .gitignore for you and add the required path to your binary files/folder(s)

• Once you added the file to .gitignore you can remove the "old" binary file with BFG.

In all these examples bfg is an alias for java -jar bfg.jar.
