how to publish a jar to NEXUS repository - gradle

Question

I want to build a jar out of my Gradle project and push it to the nexus repository. As part of this, I created a Jenkins file and added a task "publishing" task in build.gradle.
My Jenkins file:
pipeline {
agent any
environment {
NEXUS = credentials('nexus-user')
}
options {
ansiColor('xterm')
buildDiscarder logRotator(daysToKeepStr: '30', numToKeepStr: '100')
}
triggers { pollSCM('H/5 * * * *') }
stages {
stage('Checkout'){
steps { checkout scm }
}
stage('Build') {
steps { sh "./gradlew assemble" }
}
stage('deploy') {
steps {
sh "gradle -Duser.home=\"$WORKSPACE\" --gradle-user-home=\"$WORKSPACE/.gradle\" -PnexusUsername=$NEXUS_USR -PnexusPassword=$NEXUS_PSW publish"
}
}
}
}
And build.gradle
publishing {
publications{
maven(MavenPublication){
artifactId = "testApp"
from components.java
}
}
repositories {
maven {
url = "http://localhost:8081/nexus/content/repositories/${version.endsWith('-SNAPSHOT') ? "snapshots" : "releases"}"
credentials {
username = "Dont know how to pass the username here"
password = "Dont know how to pass the password here"
}
}
}
}
Could anyone tell me how to get the username and password from Gradle and set here for publishing the jar to nexus.

Answer is:
publishing {
publications{
maven(MavenPublication){
artifactId = "testApp"
from components.java
}
}
repositories {
maven {
url = "http://localhost:8081/nexus/content/repositories/${version.endsWith('-SNAPSHOT') ? "snapshots" : "releases"}"
credentials {
username = "nexusUsername"
password = "nexusPassword"
}
}
}
}
