Jenkins管道脚本和docker maven图像的问题

我尝试在docker容器中构建我的项目,图像如下所示：

FROM maven:3.3.9-jdk-8
WORKDIR mvnBuildDir
ENTRYPOINT ["mvn"]

如果我像下面那样运行我的容器,一切正常.

docker run -v /home/user/Worspace/myMavenProject:/mvnBuildDir myMaven3 clean package

但如果我在我的Jenkinsfile中尝试这个,我得到一个错误,它告诉我什么.
Jenkinsfile：

//...
def maven = docker.image("myMaven3");
maven.inside("-v ${workdir}:/mvnBuildDir"){
    stage "build and test"
    sh "mvn clean install"
}
//..

错误：

[Pipeline] {
[Pipeline] stage (build and test)
Entering stage build and test
Proceeding
[Pipeline] sh
[master] Running shell script

[Pipeline] }
$docker stop 1fc920c00b46a1038b0f39e2adc6e67f702d48ccf10d3e0bb3514d1cee3a795b

有没有人知道这里的问题是什么,或者有任何其他解决方案如何在docker容器内构建我的项目？
我的整个工作区都映射到容器内部,所以问题不在于我认为没有找到pom或其他东西.如果我运行’mvn –version’,我得到了正确的输出.
谢谢到目前为止.
