Xcode Continuous integration - latestRunSubStatus = internal-credential-server-error

Question

Greetings.
I have been trying to make continuous integration build using Bots with Xcode 5.1(5B130a) from Xcode server (3.1.1). The SCM is configured with external svn repository, which am able to successfully browse from safari.
Am trying to make integration from server web portal & as well as using xcode from development mac. Unfortunately both are failing with "internal-credential-server-error".After chasing my tail fro quite some time, I could get rid of "Internal-checkout-error" , however got stuck again with "internal-credential-server-error".
Though I see some similar errors in other posts, none of them seem to have this particular error. Hence, wanted to know where should I be storing my SVN credentials for successful svn checkout?
Here is the excerpt of my log highlighting the error:

Any help is greatly appreciated!

Answer 1

Did anyone find a way around this? I have the exact same error and tried the exact same solution.
The Xcode 5 release notes described a problem that sounds similar.
Communicating with a remote SVN repository over HTTPS can fail with an error similar to “Error validating server certificate for server name.” Edit the file /Library/Server/Xcode/Config/xcsbuildd.plist and change the TrustSelfSignedSSLCertificates key from false to true. Then, from a Terminal window, run: sudo killall xcsbuildd. 14639890

I haven't found a similar fix for Xcode 6 though.
