SVN Error: "' 'x' isn't in the same repository as 'y' " during merge

Question

I get the error

svn: 'x' isn't in the same repository as 'y' "

during merge. What's the problem and how can I fix it ?

(I actually know the answer and posting it as soon as I am allowed by the system, so that it's googleable by others. I got my share of trouble finding the answer).

Answer 1

The problem lies in the fact the checkout information is different from what you specify in the svn merge command. Typically, it can be either:

• the hostname is different when you did the checkout. You did the checkout as from svn.example.com but now you are merging by referring to an host alias, like svn-alias.example.com. note that even the case is important. You can get this error if you do svn merge from SVN.EXAMPLE.COM. More on this here and here.
• the protocol is different from what you used for the checkout. E.g. http://svn.example.com versus https://svn.example.com Make sure you use the same protocol.
• you are specifying a username at svn merge in the form [email protected]. Try to remove the user@ specification (the user is passed anyway). svn considers the hostname, and thus the repo, different if you specify the user, even if the user is technically the same.

Answer 2

this is very much case sensitive. Sometimes if you right click in any branch and click merge https://mysite.com/svn/MYREPO/trunk as merge from . But my branch name has small letters for myrepo https://mysite.com/svn/myrepo/branches/mybranch. this cause me error surely check the case sensitivenes.. If its not matching type in the wizard correctly

Answer 3

The merge is case sensitive. Ensure when you do the initial checkout ensure that the name and case are the same. For example, if you checkout to "http:///ABC" ensure you enter "http:///ABC", not "http:///abc" in the "URL to merge from".
