How to import a file of classes in a Jenkins Pipeline?

Question

I have a file that contains classes. Example :

---

abstract class TestBase
{
    String name
    abstract def fTest()

    def bobby(){
        return "bobby"
    }
}
class Test extends TestBase
{
    def fTest(){
        return "hello"
    }
}
class Test2 extends TestBase
{
    def fTest(){
        return "allo"
    }
    def func(){
        return "test :)"
    }
}

I want to import the file in my Jenkins pipeline script, so I can create an object of one of my class. For example :

---

def vTest = new Test()
echo vTest.fTest()
def vTest2 = new Test2()
echo vTest2.func()

---

How can I import my file in my Jenkins Pipeline ? Thx.

Answer 1

you can do like this:

Classes.groovy

class A{
    def greet(name){ return "greet from A: $name!" }
}

class B{
    def greet(name){ return "greet from B: $name!" }
}

// this method just to have nice access to create class by name
Object getProperty(String name){
    return this.getClass().getClassLoader().loadClass(name).newInstance();
} 

return this

pipeline:

node{
    def cl = load 'Classes.groovy'
    def a = cl.A
    echo a.greet("world A")
    def b = cl.B
    echo b.greet("world B")
}
