Eclipse Groovy dev environment other than groovy-eclipse?

[Henrik Martin]

Hi. Is there any other decent Groovy development support for Eclipse 
than the groovy-eclipse plugin? I'm using the Spring Tool Suite 
packaging of Eclipse (STS 3.7.1). I'd like to use the latest and 
greatest Groovy version, which at the time of this writing is 2.4.5 (at 
least for stable releases), but I'm not sure if groovy-eclipse has 
support for 2.4.5. Is there any other way of getting the IDE support 
features that developers are used to today for Groovy, short of 
switching to IntelliJ? I used IntelliJ about 7 years ago and liked it a 
lot, but right now I'm too bogged down to explore new tools. Hope I'm 
not opening up a can of worms here :-)
Thanks,
