Hello. I am new to groovy, assigned an effort to convert legacy python
scripts to groovy replacements. We are doing this in an effort to decouple
from dependencies on the jython engine in NiFi for scripts we run from its
ExecuteScript processor.
In one of these python scripts, this gets done to

Hello. I am trying to convert an existing script from python to Groovy. It
executes a number of os.path and os.access commands, which I've not yet
been able to find examples of that are written in Groovy. I have found
similar implementations that employ "add on" Jenkins libraries for Groovy,
but I
Hello. Newbie to Groovy. Have a text string that I need to verify is a
representation of valid JSON, or not. What is an effective means to do this
in Groovy? I'm having difficulty determining what a method like JSONSlurper
will return to me if the string can't be parsed because it is not valid
alue of idValue is " + idValue + "\nThe value of
jsonString is \n" + thisString);
println 'Valid JSON'
} catch(error) {
println "Invalid: $error.message"
}

I am having problems properly formatting Json output to requirements.
I have three fields, similar to this:
fieldA has value {"lname":"Smith", "fname":"John"}
fieldB has value {"age":"21", "gender":"M"}
fields has value 12345
I put each into an empty Groovy map, result[:] .
I'm required to

I have a Groovy list that holds the unicode representation of select
foreign language characters, something like this simplified version:

by count in an incoming document, so my

Hello. I have a task to parse dates out of incoming raw content. Of course
the date patterns can assume any number of forms - -MM-DD,
/MM/DD, MMDD, MMDD, etc etc etc. I can build myself a robust
regex to match a broad set of such patterns in the raw data, but I wonder
if there

I am struggling to build a Groovy scri[t I can run from a NiFi
ExecuteScript processor to extract from a zip file and stream to a tar
archive.
I tried to tackle it all at once and made little progress.
I am now just trying to read the zip file, and am getting this error:
