I’ve just started using subversion, and have read the official documentation (svn book), cheat sheet and a couple of guides. I know how to install subversion (in linux), create a repository (svnadmin create), and import my Eclipse project into the repository (SVN import), view the repository files (using svn list).
But I am unable to understand some of the other terminologies. For example, after importing my Eclipse project into the newly created repository I have made changes to my Eclipse project (more than 1 file). Now, how should I update the repository with this added files/changes made to my Eclipse project?
The svn update command brings the changes from the repository into your working copy – which is the opposite of what I want i.e. bring the changes I made in my Eclipse project into the previously imported project in repository. If I am correct, you update the repository more often (as you keep extending your project implementation) than your current project (with update).
Also, I do not understand when would you use svn merge. The svn book states it applies the differences between 2 sources to a working copy. Is there a scenario which would explain this?
Finally, can I have more than 1 project checked into the repository? Or is it better to create a new repository for each project?
The term you are looking for is “commit”.
Subversion does not exclusively lock a file for editing (though there is a command to do this if you really, really want to). So it is possible that you will need to merge two different users’ sets of edits on a file, or even edits from two different working copies in two different locations on your machine.
Multiple projects is fine. Best approach IMHO is repository/project/trunk etc rather than repository/trunk/project.
