Using GGTS 3.6.4
Just installed Groovy 2.4.1, and it shows up under Window=>Preferences; Groovy=>Compiler, and I see: "You are currently using Groovy Compiler version 2.4.1."
However, when I go to Project=>Properties; Groovy Compiler, I see only these 4 options under "Groovy compile level for project XxxxYyyyyZzzz":
I want to be able to designate 2.4 as the Groovy Compiler version for the project, but it's not there to pick! I've stopped/started GGTS, to no avail. What can I do?
Try changing the file .settings/org.eclipse.jdt.groovy.core.prefs wherever your workspace is for that project.
set it to:
groovy.compiler.level=24
stop/start and see if that works.
