Pass job parameter to gradle task in scripted pipeline - gradle

Question

i'm trying to convert my freestyle job in a scripted pipeline, i'm using gradle for the build and artifactory to resolve my dependecies and publish artifacts.
My build is parametraized with 3 params and in freestyle job when i configure Invoke gradle script I have the checkbox Pass all job parameters as System properties and in my
project.gradle file I use the params with System.getProperty() command.
Now implementing my pipeline I define the job parameters, I have these like enviromnent variables in the Jenkinsfile but can I pass this params to the gradle task?
Following the official tutorial to use Artifactory-Gradle plugin in pipeline I run my build with :
buildinfo = rtGradle.run rootDir: "workspace/project/", buildFile: 'project.gradle', tasks: "cleanJunitPlatformTest build"
Can I pass params to gradle build and use in my .gradle file?
Thank's

Yes, you can. If using sh ''' then switch that to sh """ to get the expanded values
Jenkinsfile
#!/usr/bin/env groovy
pipeline {
agent any
parameters {
string(name: 'firstParam', defaultValue: 'AAA', description: '')
string(name: 'secondParam', defaultValue: 'BBB', description: '')
string(name: 'thirdParam', defaultValue: 'CCC', description: '')
}
stages {
stage ('compile') {
steps {
sh """
gradle -PfirstParam=${params.firstParam} -PsecondParam=${params.secondParam} -PthirdParam=${params.thirdParam} clean build
sh """
}
}
}
}
and inside your build.gradle you can access them as
def firstParam = project.getProperty("firstParam")
You can also use SystemProperty with -D prefix as compared to project property with -P. In that case you can get the value inside build.gradle as
def firstParam = System.getProperty("firstParam")
