Define a class inside a groovy pipeline?

[Peter Berghold]

So I was playing around and tried something.   Here's a class I defined:

class MyClass implements Serializable { 

  MyClass() {

  }

  def bark(){

     sh 'echo WOOF!'

 }

}

and so I instantiate it 

def mc = new MyClass()

and I access my method

mc.bark()

and I get 

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: MyClass.sh() is applicable for argument types: (java.lang.String) values: [echo WOOF!]

So my question is: if I want to access what I perceive as normal pipeline functions from inside a class how do I do it?  What magic foo do I have to use? 

[Daniel Butler]

This is my preferred as it’s nice and explicit:

class MyClass implements Serializable { 

 

  def ctx

 

  MyClass(ctx) {

     this.ctx=ctx

  }

 

  def bark(){

     ctx.sh 'echo WOOF!'

 }

}

 

 

You’d then construct it:
def mc = new MyClass(this)

 

If you remove the class definition so you end up with a groovy file of methods you end up with class with the same name as the groovy file. Inside the class you can call pipeline steps and access the global variables like it’s a pipeline script. However I don’t think you can have anything other than a no-arg constructor.

 

 

Regards,

Daniel.
