AFAIK if you use the class com.progress.hudson.ScheduleFailedBuildsPublisher the plugin schedule-failed-builds cannot be optional it must be install.
You must use reflection here see how it's done for token macro in maven plugin: https://github.com/jenkinsci/jenkins/blob/master/maven-plugin/src/main/java/hudson/maven/AbstractMavenBuild.java#L82
