If condition for email ext in jenkins pipeline - jenkins

Question

How to send a html file in the Email body based on multiple projects?
with the below straight forward code am able to send the mail but if i use " if else condition" then its failing, is it possible to use if condition with in the format?
straight forward code:
always {
emailext mimeType: 'text/html',
body: '${FILE,path="./logs/${JOB_NAME}_Build_${BUILD_NUMBER}/misc/email_dashboard.html"}',
subject: '${JOB_NAME} Report',
to: 'xyz.com'
}
I am trying to achieve something like this:
post {
success {
archiveArtifacts 'logs/${JOB_BASE_NAME}_Build_${BUILD_NUMBER}/**/*, logs/static_results/*'
script {
load "logs/${JOB_BASE_NAME}_Build_${BUILD_NUMBER}/display/pipeline_vars.groovy"
}
}
if ((${NODE_NAME}.contains("KG"))&&(${JOB_NAME}.contains("Nightly"))) {
always {
emailext mimeType: 'text/html',
body: '${FILE,path="./logs/${JOB_NAME}_Build_${BUILD_NUMBER}/misc/email_dashboard.html"}',
subject: '${JOB_NAME} Report',
to: 'xyz.com'
}
}
else if ((${NODE_NAME}.contains("MT")) &&(${JOB_NAME}.contains("Feature"))) {
always {
emailext mimeType: 'text/html',
body: '${FILE,path="./logs/${JOB_NAME}_Build_${BUILD_NUMBER}/misc/email_dashboard.html"}',
subject: '${JOB_NAME} Report',
to: 'xyz.com'
}
}
}

Answer 1

The issue here is that you cannot have always inside an if-else block. In Declarative pipeline syntax, you will have to use if-else inside a script block as shown below:
pipeline {
agent { label 'windows' }
//agent { label 'linux' }
stages {
stage('Echo') {
steps {
echo 'Inside Echo block'
}
}
}
post {
always {
script {
if ((env.NODE_NAME == "windows")) {
echo "Running on ${env.NODE_NAME} node"
}
else if ((env.NODE_NAME == "linux")) {
echo "Running on ${env.NODE_NAME} node"
}
}
}
}
}

Below code solved my problem:
always {
script {
if (env.JOB_NAME.contains('Nightly'))
{
emailext (
to: '${DEFAULT_RECIPIENTS}',
subject: "${env.JOB_NAME}-Report",
body: '${FILE,path="./logs/${JOB_NAME}_Build_${BUILD_NUMBER}/misc/xyz.html"}',
attachLog: true,
attachmentsPattern: 'logs/${JOB_NAME}_Build_${BUILD_NUMBER}/misc/xyz.png',
)
}
}
}
