R Package checking package dependencies ERROR in Travis-ci

问题

My package passes local tests with devtools::check(), but fails to build with Travis (https://travis-ci.org/mjockers/syuzhet). Travis reports a "checking package dependencies ... ERROR" because the openNLP Package is required but not available. What is the trick to making the package available to Travis? Package is here: https://github.com/mjockers/syuzhet

回答1:

I needed to update my .travis.yml file to load java, which the openNLP package requires.

I updated .travis.yml by adding

language: java

and

install:
  - sudo R CMD javareconf

The complete working version is at https://github.com/mjockers/syuzhet/blob/master/.travis.yml
