Get class methods and parameters

Hudson.instance.items.each { job ->

// Prints all the parameters from the object
job.metaClass.properties.each {println it.name}

// Prints all the methods from the object
println("Methods: " + job.metaClass.methods*.name.sort().unique())

}

// Prints all of jenkins internal configurations
def instance = Jenkins.getInstance()
instance.metaClass.properties.each {println it.name}

// Print lines to show values from properties
def items = Jenkins.instance.getAllItems()

items.each { item ->
  	println "\n================================================"
  	println item.name
  	println item.class
  	println ""
  
	item.metaClass.properties.each {
    	println "println \"${it.name}: \${item.${it.name}}\""
	}
	println("\nMethods: " + item.metaClass.methods*.name.sort().unique())

}
