Migration page for 1.77 deprecates pipeline trigger, so trying to migrate to new syntax. 

Change my jobs from:
triggers {
  cron('@daily')
}

To:
properties {
pipelineTriggers {
triggers

}
}

DSL processing now fails with:
13:02:42 ERROR: (fullbyacct.groovy, line 8) No signature of method: javaposse.jobdsl.plugin.structs.DescribableListContext.cron() is applicable for argument types: (java.lang.String) values: [@daily]
13:02:42 Possible solutions: grep(), print(java.io.PrintWriter), print(java.lang.Object), grep(java.lang.Object), wait(), find()

Am I missing something?
