The following solution was found online and has not been tried.
After the SVN server changes the IP address, a svn server should be set up to reconnect to the local SVN server. Due to changes in the working environment, you have to modify the IP address of the server. After the IP address is changed, the client can relocate the connection to the server using the following methods:
1. If the client tool isTortoiseSVNRight-click the work copy, select TortoiseSVN-> relocation, and enter a new URL.
2. If the client tool is an eclipse plug-inSubclipseSwitch to the perspective of "SVN Resource Library", right-click the resource library path, and then locate again ..., Enter a new URL.
Another better way is
: Modify the hosts file to prevent SVN server address changes.
Add 192.168.1.254 svnserver to the last line of the C:/WINDOWS/system32/drivers/etc/hosts file.
After the above settings, the svn address is changed to http: // svnserver/svn/. In this way, if the svn address is changed, you only need to modify the hosts file.
