Docker Jenkins - Automatically installed Maven + Open Java not working together

Question

Jenkins

Installed from docker image jenkinsci/docker - README.me

Plugins

configureTools

JDK :
- name : Java 10
- install automatically : true (extract *.zip/*.tar.gz)
- url : https://download.java.net/java/GA/jdk10/10.0.2/19aef61b38124481863b1413dce1855f/13/openjdk-10.0.2_linux-x64_bin.tar.gz
Maven :
- name : Default
- install automatically : true (Install from Apache)
- version : 3.6.0

Jenkinsfile

pipeline {
    agent any

    stages {
        stage('Clean') {
            steps {
                withMaven(maven: 'Default',jdk: 'Java 10') {
                    sh "echo JAVA_HOME=$JAVA_HOME"
                    sh "mvn clean"
                }
            }
        }
    }
}

Error

[Pipeline] {

+ mvn clean -B -V
----- withMaven Wrapper script -----
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program

[Pipeline] }

Question
What I don't understand is why the $JAVA_HOME is incorrect ? (should be /var/jenkins_home/tools/hudson.model.JDK/Java_10/jdk-10.0.2, no ?)
I've try to set it on the global properties of the jenkins system configuration, but I've get the same output/error (and don't want to set it here as there can be other java_home for other java installation)
What am I missing ?

EDIT Opened an issue to Jenkins (Jira - JENKINS-54959)

EDIT 2
After some discussion with the Jenkins crews, we finally found the missing option. As the archive contains a subdirectory (here jdk-10.0.2), we need to inform the de-zipper with the subdir field

Optional subdirectory of the downloaded and unpacked archive to use as the tool's home directory

so now, I got the error

According to [this blog about declarative maven project](https://jenkins.io/blog/2017/02/07/declarative-maven-project/) I found via [this answer](https://stackoverflow.com/a/43254747/201725) to a related question you should have a `tools` section in the pipeline stating you want to use the tools. It is common to have many tools, but only use a few in each pipeline, so you have to tell it. — Jan Hudec, Nov 30 '18 at 08:59
shouldn't need to declare ``tools`` section as I'm using withMaven (I added the plugin on the description) But I've tried (in case of), but same error, the ``JAVA_HOME`` is still incomplete — LE GALL Benoît, Nov 30 '18 at 13:50

This seems to work if you set the "Subdirectory of extracted archive" of the JDK configuration:

What version of Jenkins were you running? I have `Jenkins ver. 2.204.2` and when checking the box `Install automatically` and clicking options from drop-down (i.e. Extract *.zip, etc.) does not show other fields. – Raf Feb 06 '20 at 15:50
