Most of the time, we can install the svn plug-in online:
In eclipse, under the help-> Software Updates-> Find and install... menu.
In the displayed dialog box, enter http://subclipse.tigris.org/updateas url1_new remote site.
You can have eclipse automatically download and install the svn plug-in for you. After the installation is successful, restart eclipse!
Another way is to download the compressed package for offline installation, which is also a way to install the svn plug-in.
Before eclipse4.3, we can directly pressurize the compressed package and overwrite it to the eclipse root directory. However, after 4.3, this method cannot be installed. You can see that there is a dropins directory in the eclipse root directory, that is, it directly copies all the unzipped plug-in files to this directory, and re-starts eclipse to install it !!!
