For the time being I'm disabling the Staging View in Windows > Preferences> Team > Git > Committing, opting to use the old-fashioned Commit Dialog (the one from Eclipse Mars) instead. I don't have time to muck around with extra listbox selections, mouse clicks, and context menu selections just to commit my code.

I hope someone else comes up with a better answer. The Git Staging View was interesting... but not if it slows me down.

I am not expert but i have done this once

think simple and straight way is

1.Download Git to your system

2.cd to your eclipse prject cd /workspace/sampleproject

3.Commands

git config --global user.name "Your Name Here"
git config --global user.email "[email protected]"
touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/gitusername/reposname.git
git push -u origin master                   this line may throw an error but no problem

4.From eclipse ->Help->eclipse marketplace ->search for 'git' -> install 'Egit-git team provider'

5.Go to eclipse ->Windows ->Open perspective ->Git repository

6.From Git repository view on the left side on 'Add existing local repos' then browse to '/workspace/sampleproject'

7.Now Right click on this added Repository location and add comments press Commit.

8.Now Right click on this added Repository click Push

      By default Configured remote repository should be checked then press Next
      From Source Ref and Destination Ref  Select HEAD    //you may change if u want
      Select next give your github username and password then click on Finish.
