A case that causes the GitHub Pages build to not start

Solved! Go to Solution.

Notes: All the repos mentioned below are public.


I develop in jekyll-theme project chirpy and its Travis-CI build script performs two tasks in sequence:


  1. Build a live demo site for chirpy and push the result to the repository chirpy-demo
  2. Build my blog site and push the site files to the repository


After the completion of CI work, the GitHub Pages build of chirpy-demo will be triggered immediately but not for the repos

So I used the RESTful API in Travis-CI build to trigger the Pages build of and it works.
To recover from the non-triggered build, I stopped sending the API trigger and here is the link to the non-triggered result:


In repos,


Is there a restriction that does not allow two Pages sites to be built at the same time?

Re: A case that causes the GitHub Pages build to not start

You can run two Pages builds at the same time, yes. They may not be run concurrently, but they'll both be queued.


From your description, however, it sounds like the behavior you're describing is expected. Here's what I understand from your post:


  1. You had a setup where you would push first to chirpy-demo, then to cotes2020 and only chirpy-demo Pages build would get triggered
  2. Then you added something that specifically triggered a Pages build for cotes2020. This made both sites build
  3. Then you took out the thing you added. Now only chirpy-demo builds automatically again


If my understanding is correct, then this sounds like you don't have cotes2020 configured to build correctly. Unfortunately, we don't have access to your repository's configuration details. You'll need to contact private support to help debug why cotes2020 isn't building automatically. You can contact them at or by email at


I'm sorry I couldn't be more help but please let me know if I've misunderstood.

Hi @lee-dohm


Your understanding is absolutely correct and sorry for my bad English. I got in touch with GitHub Developer Support  a few days ago and they are dealing with this issue.


Thanks for your reply.
