groovy: groovysh interpreterMode preference not working

Question

I am trying to set interpreterMode in groovysh. I open up groovysh and execute set interpreterMode, but then when I try to use def x=1, x does not get set:

groovy:000> set interpreterMode
groovy:000> set
Preferences:
    interpreterMode=true
groovy:000> def x=2
===> 2
groovy:000> print x
ERROR groovy.lang.MissingPropertyException:
No such property: x for class: groovysh_evaluate
        at groovysh_evaluate.run (groovysh_evaluate:2)
        ...
groovy:000>

What am I doing wrong?

Answer 1

interpreterMode was added in Groovy 2.4, so while you are correctly setting the preference, the Groovy shell does nothing with it. You can set anything as a preference:

groovy:000> set foo
groovy:000> set
Preferences:
    foo=true
