Hi Tison, I am not sure what you are asking... groovysh is the "Groovy Shell" so you should see a terminal window named "GroovyShell" launched that allows you to execute Groovy commands interactively. This is the expected behaviour. Or are you just pointing out the exception when quitting groovysh? How did you kill groovysh? With the Unix `kill` command (or Windows equivalent) or using one of the "exit" commands in the shell itself (:exit, :x, etc)?
I suspect you may simply want the `groovy` command that you can use to run Groovy scripts/programs. $ echo "println 'hello world'" > test.groovy $ cat test.groovy println 'hello world' $ groovy test.groovy hello world Hope this helps, Keith > On Oct 11, 2018, at 10:54 PM, Tzu-Li Chen <wander4...@gmail.com > <mailto:wander4...@gmail.com>> wrote: > > Hi Groovy community, > > I am new to Groovy and when running `groovysh` with "3.0.0-alpha-3, JVM: > 1.8.0_171" on macOS, I see a, hmm, Java monitor(?), named "GroovyShell" > launched. > > If I kill it, process `groovysh` quit with exception below.
