title: Gitignore not ignoring certain project.properties
body: <p>I am using the github app for windows and mac and I am having a problem with my .gitignore file. </p>
  
  <p>I am trying to ignore the project.properties file that gets generated when switch between my two machines but I simply cannot seem to get it to work. </p>
  
  <p>Below is a copy of my .gitignore, and it seems to be working well for everything except for the project.properties, as well as the gen/* that I have in there yet that is less annoying. </p>
  
  <p>I have been researching this for a while and haven't found an answer, I would appreciate any help! </p>
