How do I get a new branch to show up in Eclipse Git Remote Tracking?

In the Git Repositories view:

1. Right-click the repository and choose Fetch from Upstream
2. If the new branch will not shown up below Branches/Remote Tracking, you have to configure fetch:
   1. Right-click the fetch node below Remotes/origin and choose Configure Fetch...
   2. In the Configure Fetch make sure there is only the single Ref mapping (assuming the remote is named origin) +refs/heads/*:refs/remotes/origin/*:
      

In case you do not see Fetch from Upstream after right-click the repository, you may look for Fetch from origin.
