How to install java 13 on Azure-pipeline Ubuntu agent and use it during Maven build?

Question

I am trying to build a Java Maven application and run some tests against a Postgres db.

However, the java app uses JDK 13 and the Azure hosted agent ubuntu doesn't have this default installed. As such, I use the script task to install it, then use it during the Maven build.

However, I tried several config's and in all Maven keeps complaining that it can not found any JDK 13 installed.

The last config I tried is listed below, in which I install it through a script and then use the JavaToolInstaller task to make it available (ensuring the Java_home is set and the java can be found in the path. I then get the error

##[error]Java 13 is not preinstalled on this agent

I also tried it without the JavaToolInstaller task and then export JAVA_HOME and modify the PATH in the script, but then Maven complaints it can not find JDK 13...

Please some help how to use JDK 13 on an ubuntu agent during the maven build?

"PreInstalled" feature allows you to use Java versions that are pre-installed on the Microsoft-hosted agent. You can find available pre-installed versions of Java in Software section:

I think your script does not work on hosted machine somehow. And, the JDK version you specify is not present on your host machine. I would suggest you to set your Host machine as per the above table (as per pre-defined JDK installed).

Consequently, the other two options can be leveraged:

Here's an example of getting the archive file from a local directory on Linux. The file should be an archive (.zip, .gz) of the JAVA_HOME directory so that it includes the bin, lib, include, jre, etc. directories.

 - task: JavaToolInstaller@0
    inputs:
      versionSpec: "11"
      jdkArchitectureOption: x64
      jdkSourceOption: LocalDirectory
      jdkFile: "/builds/openjdk-11.0.2_linux-x64_bin.tar.gz"
      jdkDestinationDirectory: "/builds/binaries/externals"
      cleanDestinationDirectory: true

Here's an example of downloading the archive file from Azure Storage. The file should be an archive (.zip, .gz) of the JAVA_HOME directory so that it includes the bin, lib, include, jre, etc. directories.

- task: JavaToolInstaller@0
  inputs:
    versionSpec: '6'
    jdkArchitectureOption: 'x64'
    jdkSourceOption: AzureStorage
    azureResourceManagerEndpoint: myARMServiceConnection
    azureStorageAccountName: myAzureStorageAccountName
    azureContainerName: myAzureStorageContainerName
    azureCommonVirtualFile: 'jdk1.6.0_45.zip'
    jdkDestinationDirectory: '$(agent.toolsDirectory)/jdk6'
    cleanDestinationDirectory: false

It's possible a good solution, but sorry, it was not the solution that I used for my problem, see my own answer below — edbras, Mar 14 '21 at 21:17

The problem was that I was pointing to the wrong installed directory. The above location of JAVA_HOME I found on internet, after ouputing the tree content of the /usrl/lib/jvm I changed it and added this to the variable section and maven found the jdk and uses it

JAVA_HOME_13_X64 : "/usr/lib/jvm/java-13-openjdk-amd64"
