Spring Cloud Config failed to get the configuration from local gitlab using git

Question

I’m trying to setup the Spring Cloud Config Server using default git backend. I have setup a local gitlab and put the configuration files into local gitlab. But when I started the config server, the following exception is thrown, Where am I going wrong? And are there any ways to configure the JGitEnvironmentRepository not to verifySSL by default?

I was having the same problem and found that you can resolve the issue by adding ".git" to the uri. I presume that GitHub automatically forwards to the ".git" uri if it sees that the request is not from a web browser, where GitLab does not. So just change your config to:

spring:
  application:
    name: configserver
  cloud:
    config:
      server:
        git:
          uri: https://10.200.78.100/testing/configuration-repo.git
          basedir: E:/service-config/
server:
  port: 8888

AFAIK JGit reads your .git config files in a standard way, so you should be able to set http.sslVerify (e.g. like this post: How can I make git accept a self signed certificate?).

Thanks a lot Dave! I have changed .git config files for disabling SSL verify. But the exception "org.eclipse.jgit.api.errors.RefNotFoundException: Ref master can not be resolved" still there, I have not found how to resolve this exception for local gitlab. Current My workaround is to use Github to host my configuration. – Billarch Jan 05 '15 at 05:00
My guess is you don't actually have a master branch then? – Dave Syer Jan 05 '15 at 08:12
Well, I get the same stack trace, and I most definitely do have a master branch. Of course, it could still be the case here. For my own case, I suspect some authorization issues. – Michael Piefel Feb 09 '15 at 19:12
