Unable to resolve class groovyx.gpars.actor.Actors.actor

I am trying to run the Hello World example from here http://www.gpars.org/webapp/guide/index.html#_download_and_install But I get the error: Unable to resolve class groovyx.gpars.actor.Actors.actor

I'm using groovy version 2.4.16 and JVM 11.0.3 on linux

This is the code..

import static groovyx.gpars.actor.Actors.actor

def decryptor = actor {
    loop {
        react { message ->
            if (message instanceof String) reply message.reverse()
            else stop()
        }
    }
}

def console = actor {
    decryptor.send 'lellarap si yvoorG'
    react {
        println 'Decrypted message: ' + it
        decryptor.send false
    }
}

[decryptor, console]*.join()
Solution

  • To get this working I had to do completely remove the old groovy and install the new version with sdkman. Like so..

    $ apt remove groovy
$ curl -s "https://get.sdkman.io" | bash
$ source "$HOME/.sdkman/bin/sdkman-init.sh"
$ sdk install groovy

    In my case I also needed to add the JAVA_HOME variable.
