一：生成build.gradle文件

gradle init --type pom

二：修改或者替换build.gradle文件内容如下

buildscript {
    repositories {
        jcenter()
        maven {
           url "https://plugins.gradle.org/m2/"
          }
    }
    dependencies {
        classpath("io.spring.gradle:dependency-management-plugin:1.0.0.RELEASE")
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.5.RELEASE")
        classpath "org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.7.1"
    }
}

repositories {
    jcenter()
}

apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: "org.sonarqube"

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    compileOnly('org.projectlombok:lombok:1.16.18')
        annotationProcessor('org.projectlombok:lombok:1.16.18')
}

三：配置sonar认证权限信息(在该目录中创建 ~/.gradle/gradle.properties)

    systemProp.sonar.host.url=http://10.100.10.22:9000
    systemProp.sonar.login=admin
    systemProp.sonar.password=admin

四：在项目根目录执行编译和扫描动作

stage("gradle and sonar"){
        steps{
              script {
                  def timeStamp=new Date().format("yyyy-MM-dd");
                  def targetDir="${WORKSPACE}/${params.targetDir}";
                  dir(targetDir){
                      withSonarQubeEnv('sonarqube-jenkins') {
                          print "repoBranch : ${params.repoBranch}"
                          sh "gradle clean build -x test sonarqube -Dsonar.projectKey=${params.projectKey} -Dsonar.projectName=${params.projectKey} -Dsonar.sourceEncoding=UTF-8 -Dsonar.analysis.buildNumber=${env.BUILD_NUMBER} -Dsonar.analysis.jobName=${env.JOB_NAME} -Dsonar.host.url=http://10.100.21.3:9000 -Dsonar.login=admin  -Dsonar.password=admin -Dsonar.java.binaries=build/classes -Dsonar.java.sources=src/main/java -Dsonar.analysis.isFortify=true -Dsonar.projectDate="+timeStamp
                      }
                  }
        timeout(1) {
            sleep(5)
            def qg = waitForQualityGate() 
            if (qg.status != 'OK') {
              error "未通过Sonarqube的代码质量阈检查，请及时修改！failure: ${qg.status}"
            }
       }
            }
     }
}

五：接下来会生成code quality报告，在sonar的web页面查看
