Why is this CC.NET error so cryptic? What is going on?

Question

I'm trying to do a branch build. I've just set it up and forced a build and all I'm getting, almost immediately after the build starts is that it failed.

Nothing even remotely helpful in this error. Just wondering if anyone has come across anything similar.

ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: . Process command: C:\Program Files (x86)\CollabNet Subversion Server\svn.exe update D:\WC40\SVN\\\ --non-interactive --no-auth-cache

Answer 1

Try increasing the log level in your cc.net configuration to see what's happening before the failure.

Answer 2

my guess is that you call the same repository simultaneously from 2 builds, svn is locked while it is getting the code and hangs... the solution is to use queues and priority:ccnet documentation
