Scripts

script {
    // Trigger by another webhook
    def upstreamCause = currentBuild.rawBuild.getCause(hudson.model.Cause$UpstreamCause)
    UPSTREAM = upstreamCause
    // Get build number from trigger webhook
	def upstreamBuild = Jenkins.instance.getItemByFullName(upstreamCause?.upstreamProject).getBuildByNumber(upstreamCause?.upstreamBuild)
    // Get environment action from trigger webhook
	def upstreamEnv = upstreamBuild.getAction(org.jenkinsci.plugins.workflow.cps.EnvActionImpl).getEnvironment()
	PARENT_ENV = upstreamEnv
    // Trigger by user
    def isStartedByUser = currentBuild.rawBuild.getCause(hudson.model.Cause$UserIdCause) != null
    // Get all Causes for the current build
    def causes = currentBuild.rawBuild.getCauses()
    println causes
}
