I have installed Groovy 3.0.2 using sdkman! on OSX 10.13.6 and 'which groovy' reports /Users/adrian/.sdkman/candidates/groovy/current/bin/groovy
But when I attempt to use Eclipse (2020-03 4.15.0) it won't pick up anything but the basic groovy packages - so hence code with imports like groovy.cli.commons.CliBuilder (the jar for that is in ~/.sdkman/candidates/groovy/current/lib) fail.
How do I fix this? (I can see no obvious way and I cannot even pick a directory name that begins with . in the IDE tools)
