I previously asked this in rOpenSci's slack, but unfortunately haven't figured out a solution yet. I am seeing the following error on Travis when trying to test a package of mine. I've created a simple test project to try to isolate the problem, and it seems to be related to a dependency issue (build link):
Error: (converted from warning) unable to access index for repository /src/contrib: cannot open URL '/src/contrib/PACKAGES'
My package depends on another package that is available through a repository my employer set up. I'm listing this repository in the DESCRIPTION under
Additional_repositories, which I believe is the correct way to list alternate repositories (and previously worked fine with Travis).
Locally, I can install this dependency with
install.packages("synapser", repos = "https://sage-bionetworks.github.io/ran").
Does anyone know why I'm seeing this Travis failure?
