I am wondering is there no Groovy Support more in STS. I just wanted to give Groovy and Gradle a try with a new mini project and I remember in the past time there were a GGTS (Groovy&Grails Tool Suite).
Somehow I am not finding any Groovy IDE what works in STS 3.9.0 (Neon). Am I missing something?
Pivotal has dropped support for groovy in 2015 and with that the development of GGTS and the groovy plugin.
Fortunately the groovy-eclipse plugin is in development again, but there was no release for quite a while. The snapshot builds are stable enough in my opinion.
