任务＆＃39;文件＆＃39;在根项目中找不到

Question

我有Jenkinsfile将我的工件部署到JFrog Artifactory

node() {

def server
def buildInfo
def rtGradle

stage('Clone') {
   ///my gitlab url
}

stage('Artifactory configuration') {
     server = Artifactory.server 'my-server-id'
     rtGradle = Artifactory.newGradleBuild()
     rtGradle.tool = 'Gradle 4.6' // Tool name from Jenkins configuration
     rtGradle.deployer repo: 'epm-lstr-hri-maven', server: server
     rtGradle.resolver repo: 'epm-lstr-hri-maven', server: server
     rtGradle.deployer.deployArtifacts = false
     buildInfo = Artifactory.newBuildInfo()
}

  stage ('Build') {
    rtGradle.run rootDir: ".", buildFile: 'build.gradle', tasks: 'build'
}

stage ('Deploy') {
    rtGradle.run rootDir: ".", buildFile: 'build.gradle', tasks: 

'artifactoryPublish', buildInfo: buildInfo
        rtGradle.deployer.deployArtifacts buildInfo
    }

    stage ('Publish build info') {
        server.publishBuildInfo buildInfo
    }
}

运行此作业后，将显示异常：

[Pipeline] newBuildInfo
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Build)
[Pipeline] newBuildInfo
[Pipeline] ArtifactoryGradleBuild

FAILURE: Build failed with an exception.

* What went wrong:
Task 'Files' not found in root project 'common-api'.

Gradle中的任务＆＃39;文件＆＃39; 是什么？我的项目中没有，我如何使用pipline部署工件？
