You will need to add the following environment variables to your travis yml
PLUGIN
being the wordpress repo slug
MAINFILE
being the name of the main plugin file
For ex.
PLUGIN="bmlt-wordpress-satellite-plugin"
MAINFILE="bmlt-wordpress-satellite-plugin.php"
This is done automatically upon tagging a release. If you wish to tag a release for testing or a beta release make sure the tag name contains the word beta in it as the deployment to wordpress will be cancelled. For ex. 3.9.6-beta
If you wanted to test deployment without the final svn commit add a hyphen -
in your tag without the word beta.
