Some builds are failing in Travis with the error below:
No compatible version of PHP_CodeSniffer was found; you must have 1.3.4 or higher. Alternatively, you can symbolically link with the following command: sudo ln -sv /home/travis/drupal-7.50/sites/all/modules/coder/coder_sniffer/Drupal
$(pear config-get php_dir)/PHP/CodeSniffer/Standards/Drupal
Seems like we need some additional travis configuration.
Compared to other modules that work.
