I'm trying to add a remote linux SVN repository to my project but when I enter the server address I get the message Host is unreachable.
I'm entering it like
svn://ip_address/myproject/
From terminal I can do this
svn list svn://ip_address/myproject/
and it shows the contents without any issues.
I had this problem as well in linking to a Git repository. It seems XCode has some issues with IP addresses. I found that by modifying my hosts (/private/etc/hosts on Mac) file and adding an entry for the repository's IP address does the trick.
Hosts file entry:
i.p.add.ress serverName #where i.p.add.ress is your ip_address
In the Location field in XCode:
svn://serverName/myproject
The comments above referencing the other question's answer doesn't cover the IP address issue. Hopefully this will fix your issue too.
To modify the host file you open the terminal and put this command:
sudo nano /private/etc/hosts
Now you have opened with "nano editor" the file hosts, add IP, save and close. After you put this code in the terminal to reflush dns:
dscacheutil -flushcache
END!
This is probably not the solution to the issue the original poster was experiencing, but the same error message can be received for a different reason, which is why I post this.
Xcode has trouble with ssh login banners.
Quite simply, if your svn server is accessed via svn+ssh and is making use of a login banner, Xcode will state that your repository cannot be reached. Comment out the Banner entry in /etc/sshd_config, and there should be one less reason why you cannot reach your repository.
I also came across this with hard luck. How I fixed my broken repository is as follows.
- Start XCode and check out or clone a new repository.
- Copy the git HTTPS clone URL.
- Paste into the Xcode field and remove the "S" of HTTPS.
- Press clone button
- When the "verify Certificate" popup appears make sure to set it to "Always Trust"
- If needed to enter git username password save that to the keychain.
- In the original "broken repository" Open the XCode organizer click the remotes folder and expand "origin"
- If no branch appears enter username and password and the remote will now appear
Hope this helps
