How to define global variables in groovy file, which I want to load and consume?

Question

I have a Jenkins parent groovy file which consumes the child groovy file

Parent grooy file:

...
def child = load 'child-groovy-file';
child.execute();

Child groovy file:

a = "first letter";
b = "second letter;
def execute
{
echo "a is "+a;
...
}

But this is not working. Unable to access variables, which are defined in Child Groovy file, when trying to access from Parent groovy file. When I create a node block and trying to consume directly the child groovy file, It is working.

Is the Environment variables only the solution to access globally?

Solution

try this one

static void main(String[] args) { 
      // Initializing 2 variables 
      def x = 5; 
      def y = 10;

      //Performing addition of 2 operands 
      println(x+y);
 }

}
