Grails 2.5.0 comes with Groovy 2.4: http://grails.1312388.n4.nabble.com/ANN-Grails-2-4-5-and-Grails-2-5-0-released-td4658938.html

what also is good to know is that Groovy >= 2.3 is needed for JDK 8 ...

Thanks @rdmueller, I've updated the list. That's a good point about the JDK, I'll make a note when I'm back at my machine.

Grails 2.5.3 contains Groovy 2.4.4

Would be great if a maximum and minimum JDK version per groovy version is included

currently I am using grails 1.1.1.
grails 1.1.1 will support java 1.7?

3.3.3     2.4.14  https://github.com/grails/grails-core/blob/dd4dfa01cb263637dd32c76146dc9377e28ba45f/build.gradle#L43

3.3.3     2.4.14  https://github.com/grails/grails-core/blob/dd4dfa01cb263637dd32c76146dc9377e28ba45f/build.gradle#L43
3.2.12    2.4.11

Thanks @verglor

I would think this is where the groovy version is specified

https://github.com/grails/grails-core/blob/v4.0.8/gradle.properties

Hi Igor,
I think the version for 4.1.0 needs to be fixed, https://github.com/grails/grails-core/blob/v4.1.0/gradle.properties says for the Groovy Version 2.5.14, the build.gradle file points to the project map these days:
groovyVersion = System.getenv('CI_GROOVY_VERSION') ?: project.groovyVersion

Thanks @Frankst2 --fixed.
