Hello there !

When configuring any project to use a gogs repository browser, as part of "Git Source Code Management", configuration is not reachable anymore, stuck on a grey section with "Loading".

Steps to reproduce:

• With docker and docker-compose:
  • Use this repository: https://github.com/dduportal/voxxed-lu-2016/tree/gogs-jenkins-browse-bug ( https://github.com/dduportal/voxxed-lu-2016 on branch gogs-jenkins-browse-bug)
  • Start the 2 services (Jenkins, Gogs and a Gogs configurator container) by running

    docker-compose up --build -d

    from the root of the repository

• OR with Jenkins 2.7.1 and a Gogs service running with a project inside, even an empty one
• Ensure that the git-plugin is up-to-date within Jenkins (Jenkins 2.7.1 seems to come with the git-plugin 2.5.0. 2.5.2 is the latest one for git-plugin).
• Create a new freestyle project:
  • Select Git as SCM and use one from Gogs (if in my docker-compose, use http://gitserver:3000/jenkins/demoapp.git)
  • In the SCM -> Repository Browser section, select gogs
  • Save the configuration, and try to reach it again, you're stuck in the "Loading" Screen (cf. loading.png attached screenshot)

Debug informations:

• When saving the job, I can see this stack in the Jenkins Logs (containers logs in my case):

• When going back to the config job (status stuck to loading screen), my Chrome console shows some errors. I've put them in the attached screenshot "web_console_errs.png"

Workaround

FYI, I ended up using this project: https://github.com/renannprado/gogs-repository-viewer-plugin , which an alternative Gogs Repository Browser, that works, but require more configuration, and is not pre-build plugin within the OSS Update Center.

Thanks for your hard work, don't hesitate if I missed something or if you need more informations !
