title: get changes from master after creating branch
body: <p>I am using <code>Egit</code> with <code>eclipse</code> for working on my java project. I created a branch called <code>branch1</code> from master and started working on it.</p>
  
  <p>In the mean time my colleague created another branch <code>branch2</code> from master, made some changes and merged <code>branch2</code> back to master.</p>
  
  <p>Now I need to get all the changes that were made on master to my branch <code>branch1</code>.</p>
  
  <p>How can I achieve this using <code>eclipse</code> or <code>github</code> and <strong>not using any command</strong>.</p>
