The principle is that the SVN server is generally placed on the public server, we even this server, myeclipse on the use of SVN control can download the project on the SVN to the local, so many companies will develop to use the software is put on SVN, a colleague to just connect the SVN You can get the things you need down.
Update refers to the changes on the server and you do not change locally, you need to update, update updates
Commit refers to what is not on the server, that is, what you have changed, you need to submit the code, other colleagues update your code commit commit
Synchronization, is the work done before the update submission, the update before the submission of synchronization, you can know what to submit what to update, which things are conflicting (you and the colleague changed the same file, there may be conflicts), conflict can not be submitted and can not be updated, Only if the conflicting file is selected to overwrite the file with local files or overwrite the file with the server before updating or submitting, the concrete usage also needs the landlord to practice more, this thing used once will be the above term in the MyEclipse option is
Sync: Synchronize with repository (if your project is connected to the SVN right button for your project team ... can see) Click Sync will go into the Synchronize interface and then right click on the project has
Mark as Mergerd (conflict when it conflicts with the file will be used to overwrite the server locally, meaning that with your!) Override and update (when the conflict right-click File is selected to indicate the server!) )
