How to cleanup workspace built from docker

[Den]

Hi,

I'm building artifacts in docker image and if I'm aborting a build, the 
deleteDir function fails to delete artifacts since
they were created with root user in docker and the function is called by 
jenkins user outside of docker. Is there any workaround?

pipeline {
    agent {label 'docker'}
    stages {
        stage('Build') {
            agent {
                docker {
                    image 'adoptopenjdk/openjdk8' args '-u root -v 
$HOME/.m2:/root/.m2' reuseNode true label 'docker'
                }
            }
            stages {
                stage ('Package') {
                        sh "./mvnw package"
                }
            }
    post {
always {deleteDir()}
    } 
        }
    }
    post {
        always {deleteDir()}
    }
}
