Gradle 如何将jar发布到NEXUS存储库

我想从Gradle项目中构建一个jar，并将其推送到nexus存储库。作为其中的一部分，我创建了一个Jenkins文件，并在build.gradle中添加了一个任务“publishing”任务

我的詹金斯档案：

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"
                 
            }
        }   
        
    } 
}

还有格雷德尔先生

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"
            }
        }
    }
}

谁能告诉我如何从Gradle获得用户名和密码，并在此处设置，以便将jar发布到nexus。

答案是：

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"
            }
        }
    }
}
