Hi Tommy,
I agree: We have often found that using well established Java libraries
together with the power of the Groovy language works well & makes great
sense (e.g. Ebean ORM & Vaadin web-GUI in our case).
Groovy's integrated support (for e.g. XML/JSON) is often very dynamic in
nature, something which we often neither need nor want, and the small
overhead of writing a thin, type/schema-safe wrapper around e.g. a
generic Java XML SAX/DOM lib for a specific application case has always
turned out to be well invested & makes the code better readable and
easier to refactor.
In addition these Java libs have often been debugged and performance
optimized over the years in a way that Groovy finds hard to match, since
it would spread its development manpower very thin.
The command-line parsing library coming with Groovy nowadays is a good
example of an imho better suited hybrid approach: It supplies Groovy
goodness over an excellent existing Java library (picocli) G-)
Cheers,
mg

Hi Paul,
Thanks, but after the warning that JSONSlurper can loose order in
lists, a known bug, I decided to go with Jackson Jr, which also allows
me to parse JSON into a Map structure. But since I'm coding entirely
in Groovy using Groovys JSON support would make sense, but the pointed
out bug scared me away :-). I have used Jackson Jr before, it works well.

Hi Tommy,
I wrote a little blog post that might have some of the information you
were missing:
https://blogs.apache.org/groovy/entry/parsing-json-with-groovy
Perhaps some more of that info belongs in the official documentation.
Cheers, Paul.

The problem is that there seem to be not groovy-all for version
4.0.1. Maven completely fails when I add "-all" to "groovy" in my
poms. It will not download the groovy-all file. I deleted
~/.m2/repository and built again and it downloaded all but groovy-all.
