Jenkins Pipeline Syntax - Need to get Parameters for Job from wget - bash

Question

Im new to Jenkins Pipeline , Groovy syntax etc.
I have a Jenkins job that takes 5 parameters.
I want to schedule a pipeline that checks for listings via WGET ( format is csv - i can switch to JSON output also ) and the csv is one row with 5 parameters listed
a,b,c,d,e
I need to parse that list and pass the parameters to the
JOB "IF" there are rows , if not , skip and complete the pipeline.
I have searched and basically got as far as this for testing...:
pipeline {
environment {
testVar='foo'}
agent any
stages {
stage('Example Build') {
steps {
echo 'Hello World'
script {
sh "RESULT=\$(wget -qO- https://www.url.com/getlist)"
sh "echo \$RESULT"
//variable define based on parse of CSV???
}
}
}
stage('Example Deploy') {
when {
expression { testVar=='foo' }
}
steps {
echo 'Deploying'
build job: 'Testing', parameters:
[
string(name: 's_e', value: 'u'),
string(name: 't_e', value: 't'),
string(name: 's_s', value: 'DS'),
string(name: 't_s', value: 'SH'),
string(name: 'efg', value: 'TEST')
]
}
}
}}
Obviously i have more work to do around parse of RESULT (but I am not sure how I can achieve this in Pipeline).
I then need to check for RESULT empty or not , then pass variables to the Build.

Answer 1

I opted for a different option.
Instead I now have a Jenkins Job where I use the "Trigger/Call Builds on other Projects"
Before thats added as a build step , i have some code to get the WGET CSV information.
RESULT=$(wget -qO- https://url.com/getlist)
if [ -z "$RESULT" ]
then
echo "Nothing to do"
# exit 1
else
echo "$RESULT"
s_env_upper=$(echo $RESULT | awk -F',' '{print $1}')
t_env_upper=$(echo $RESULT | awk -F',' '{print $2}')
s_env=$(echo $s_env_upper| tr [A-Z] [a-z])
t_env=$(echo $t_env_upper| tr [A-Z] [a-z])
echo "s_env=$s_env" > params.cfg
echo "t_env=$t_env" >> params.cfg
fi
Hope this helps someone else... i was breaking my heart trying to get pipeline to do the work and answer was simpler.
