Upgrading Katalon Studio Groovy Version

I was wondering if it’s possible to update the groovy version to 2.5.7 manually or if we have to wait for Katalon Studio to make a new release. If it’s the latter, about what time would this be available?

I need to use @NamedVariant but it does not work on the current Groovy version (v2.4.7)

Thank you!

manualy is not possible. most probably will totaly crash katalon at runtime due to broken dependecies/mismatched versions
if katalon team intend to upgrade … no idea.

Hi @daniel.tran, @Ibus

We are considering to upgrade Groovy to v2.4.17 or v2.5.7 in Katalon v7.1.0 release. This release will eliminate some crashes when editing Groovy script. Please stay tuned.

Awesome. Really looking forward to that update. I have experienced lots of issues regarding crashing/freezing during Groovy scrip editing as well.

What is the timeline for the v7.1.0 release?

i bet, when the dev team will know, will tell you.
but please understand they have to analyze and prioritize the features … it’s a full process

I have looked at the v7.1.0 release and it still does not look like there is an update to v2.5.7 yet… @duyluong

@daniel.tran i think an groovy update is targeted in 8.0 beta … not sure if will suit your needs, check the pinned topic

Up ! Why don’t we use the lastest (stable) version of groovy, the 3.0.8 ? I would like to use some feature of at least the 2.5 like the jsonGenerator. Is it available in the 8.0 beta ?

The team once tried upgrading Groovy to ver 3 but found difficulties. See the following post:


Some news about Groovy 3 ?

Does Katalon support Groovy 3 ?


Some news about groovy version ?

@moustik I am certain Katalon Studio version 9 uses Groovy version 3.

I had to update all the deprecated XmlSlurper imports.
