How to use checkpoint and a MRAN snapshot as CRAN mirror with travis-ci? RRS feed

  • Question

  • I'd like to use checkpoint to set the versions of packages that get used when my package is built on Travis-CI.

    I'm looking for advice on getting either of these working:

    1. Travis using the local files (i.e. stored in the github repo of my pkg) of the packages that my package depends on. For example, if I use checkpoint to download the sources of the packages and store them in a directory with my package, how can I get Travis to install the packages from that local location, rather than from CRAN? or,

    2. Travis use the MRAN snapshot URL to download the packages archived on a specific date, as set in the URL. 

    I've been experimenting with various options in the .travis.yml file in this test package:

    So far everything has resulted in an error (, often this is the error message:

    W: Failed to fetch server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

    How can I get Travis-CI to be aware of the checkpoint package, and not contact CRAN to download dependencies?
