Question

I just want to send some messages between 2 actors in Groovy.
I receive the first messages abc , but get then the following exception:

An exception occurred in the Actor thread Actor Thread 1
groovy.lang.MissingPropertyException: No such property: act1 for class: groovyx.gpars.actor.DefaultActor

Here is my code:

import static groovyx.gpars.actor.Actors.actor

def act2 = actor {
    react {
        println it
        act1.send "def"
    }
}

def act1 = actor {
    act2.send 'abc'
    react { println it }
}

[act1, act2]*.join()

Answer 1

Try doing

def act1, act2

At the top of your script after the import statement

Then remove the 2 def keywords you currently have
