Groovy post build script trigger another project by name

[Wender Oliveira]

I would to like to create a logical Groovy script which in accord with some conditions trigger build  another project found by job name

def build = manager.build;

if(manager.build.getResult() == Result.SUCCESS){
   nivel = build.getBuildVariables().get("nivel");

   if(matcher != null && nivel == "completo"){
      //Here I would to get a Job by name
      //And build the job name
   }          
}
