/*
 * This script triggers automatic repo fetches in Redmine upon pushes.
 * It won't work out-of-box, you need to configure a few things.
 *
 * Redmine
 *  - Go to Administration / Settings / Repositories, and make sure that the
 *    "Enable WS for repository management" option is checked. Also generate an
 *    API key and take note of it.
 *  - Open a project page, go to Settings / Repositories and add a repo. Take
 *    note of the Identifier.
 *
 * Gitblit
 *  - Set the redmineProject custom field in gitblit.properties, e.g.
 *    groovy.customFields = "redmineProject=Redmine Project Identifier"
 *  - Edit the repo you added to Redmine, go to hook scripts and add this script
 *    to the post-receive hooks. Also specify the Redmine project's identifier
 *    under custom fields.
 *
 * Troubleshooting
 *  - run Gitblit interactively and check its console output
 *  - on the Redmine server, tail -f log/access.log
 *
 * If you want your repos to work with multiple Redmine projects, you don't need
 * to add the repos to all of them. Instead, add the repo to a single project,
 * then go to Administration / Settings / Repositories and enable the "Allow
 * issues of all the other projects to be referenced and fixed" option.
