Extending @razboy answer: this is good way if Cause cannot be whitelisted in sandbox. I forgot about Jenkins API and used current build console to look for string about trigger cause. You can try to fetch data from API as @razboy or get current console and grep it if you need simple stuff. Jenkins API is more flexible for more complex logic. To get API help,append /api to your build url: /job///api

   def buildUrl = env.BUILD_URL
   sh "wget $buildUrl -O currentConsole.txt"
   statusCode = sh returnStatus: true,script: 'cat currentConsole.txt | grep -q "Started by upstream project"'
   boolean startedByUpstream= statusCode==0
