jenkins how to run from jenkins gradle specify testng.xml - jenkins

Question

I'm working with jenkins and try to call a remote machine that has a java project with gradle config to run tests build.gradle
version '1.0-SNAPSHOT'
apply plugin: 'idea'
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'maven-publish'
sourceCompatibility = 1.8
version = '1.0'
sourceSets {
jars
}
repositories {
jcenter()
mavenCentral()
}
dependencies {
compile fileTree(dir: "src/jars/resources", include: ['*.jar'])
compile group: 'org.testng', name: 'testng', version: '6.9.10'
compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '3.+'
compile group: 'io.appium', name: 'java-client', version: '4.1.2'
compile 'com.testdroid:testdroid-api:2.9'
compile group: 'org.json', name: 'json', version: '20141113'
}
compileJava {
options.encoding = "UTF-8"
}
test {
useTestNG {
suites 'src/main/resources/testng.xml'
}
}
but I want to run a custom testng2.xml! so I define in jenkins a parameter test and define their testng2.xml, but and it will show in the console
/Users/jenkins/Home/workspace/AutomationGradle/gradlew -Dtest=testng2.xml clean test -i
but I can't understand how to make gradle to get the dynamic parameter

Answer 1

Use it like that, with a default value set to testng.xml
ext.testFile = System.getProperty('Test_Plan') ?: 'testng.xml'
test {
useTestNG {
suites "src/main/resources/$testFile"
}
}
And run your command line with the test parameter
/Users/jenkins/Home/workspace/AutomationGradle/gradlew -DTest_Plan=testng2.xml clean test -i

Thank you, I'v worked a lot of time on this, so I'm writing what worked for me:
In the Jeninks I added a parameter:
TESTNGFILE
In the groovy file:
-DTestNG=$TESTNGFILE
build.gradle:
ext.testFile = System.getProperty('TestNG') ?: 'regression.xml'
test {
useTestNG {
options {
systemProperties(System.getProperties())
}
systemProperties = [
TESTNGFILE: System.getProperty('TESTNGFILE')
]
suites "/src/test/resources/testng/${testFile}"
testLogging.showStandardStreams = true
useDefaultListeners = true
}
}
