I have tried to upgrade both the groovy and trails versions that come with the downloaded version of GGTS on ubuntu linux.
When I point to the SDKMan versions of groovy and trails, GGTS rejects it saying they are not valid versions.
Does anyone know of a verified way to upgrade the versions of groovy and trails that come with GGTS?
GGTS no longer support the Grails 3 series, officially. Consider using the IntelliJ editor for development.
