Over the past few days we have been seeing errors such as (note this is not consistent on which libraries will fail from what I can see):

      https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/main-settings/0.13.11/jars/main-settings.jar
        ::::::::::::::::::::::::::::::::::::::::::::::
        ::              FAILED DOWNLOADS            ::
        :: ^ see resolution messages for details  ^ ::

        :: org.scala-sbt#compiler-interface;0.13.11!compiler-interface.jar
        ::::::::::::::::::::::::::::::::::::::::::::::

This is resulting from the make target: dist/declarativewidgets/static/declarativewidgets.jar
This works locally consistently, but errors on Travis.
It looks fairly similar to travis-ci/travis-ci#3242, so I am going to open an issue on Travis and see what they say.

Was about to open an issue, but it looks like others beat me to it (~a day ago) at travis-ci/travis-ci#6641. Looks like we are not the only ones, so it's not on our end.

Link to sbt/sbt#2758 as well

The sbt build started working again this morning. Something to do with HTTPS->HTTP redirects not being allowed, though it's not clear who fixed this or how.

phantom is still failing on port 4444 however

Chrome on linux seems to have stopped working. Can't find any relevant bug reports, and reverting to older chromedrivers and selenium-standalone versions didn't seem to make any difference, so perhaps it's something else in the environment? It's possible that it's a timing issue and selenium isn't ready?

Switched to use firefox for travis PR tests rather than chrome, for now. 62511c0

There's still an intermittent problem where the R system tests timeout at 60 sec. The initial R system test sometimes takes upwards of 30 seconds (witnessed on my system)

Travis is passing at the moment. Both chrome/linux and R issues seem to have gone away.
