/**
* GitBlit Post-Receive Hook for YouTrack
*
* The purpose of this script is to invoke the YouTrack API and update a case when
* push is received based.
*
* The Post-Receive hook is executed AFTER the pushed commits have been applied
* to the Git repository. This is the appropriate point to trigger an
* integration build or to send a notification.
*
* If you want this hook script to fail and abort all subsequent scripts in the
* chain, "return false" at the appropriate failure points.
*
* Bound Variables:
* gitblit Gitblit Server com.gitblit.GitBlit
* repository Gitblit Repository com.gitblit.models.RepositoryModel
* receivePack JGit Receive Pack org.eclipse.jgit.transport.ReceivePack
* user Gitblit User com.gitblit.models.UserModel
* commands JGit commands Collection<org.eclipse.jgit.transport.ReceiveCommand>
* url Base url for Gitblit String
* logger Logs messages to Gitblit org.slf4j.Logger
* clientLogger Logs messages to Git client com.gitblit.utils.ClientLogger
*
*
* Custom Fileds Used by This script
* youtrackProjectID - Project ID in YouTrack
*
* Make sure to add the following to your gitblit.properties file:
* groovy.customFields = "youtrackProjectID=YouTrack Project ID"
* youtrack.host = example.myjetbrains.com
* youtrack.user = ytUser
* youtrack.pass = insecurep@sswordsRus
