when fork other's project in github,to obtain the newest version,you need to do:

  1. clone your fork project into local path:

    git clone https://github.com/your_github/EventBus.git

  2. try git remote -v,if you can only see yourself origin(fetch/push),then you have to add the man repo manually: 


    git remote add upstream https://github.com/greenrobot/EventBus.git

  3. then,merge the main repo

    git fetch upstream

    git merge upstream/master

    so far,you local project is the newset version.but your github remain the same.so you have to push the newest to github.

  4. git push origin master
