Install AdoptOpenJDK / Adoptium onto Ubuntu

  • 772

I downloaded Java 11 in the form of OpenJDK from AdoptOpenJDK. From the tar.gz file I can extract a folder named jdk-11.0.3+7 with nested folders for bin, conf, lib, and so on. But no installer app found there.

➥ How should I install this downloaded Java release onto Ubuntu?

I can cd into the bin folder and execute commands like ./java --version. But I wonder if there is a usual routine for placing the Java implementation somewhere specific, and arranging environment variables, setting default path, etc. On macOS, an installer does all that for me automatically. As I newbie on Ubuntu, I'm uneducated.

Older Questions such as this one ask about using apt-get. My Question is not a duplicate, as here I am asking about downloads from AdoptOpenJDK rather than via package-installer such as apt-get.

    AdoptOpenJDK is now superseeded by Adoptium

    How to properly install Temurin JDK with update-alternatives

    Adoptium provides a Debian / Ubuntu repository

    wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo apt-key add -
echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list
sudo apt update
sudo apt install temurin-8-jdk
sudo apt install temurin-17-jdk

    AdoptOpenJDK provides a Debian / Ubuntu repository.

    You can install using the package management system, which is much simpler than installing it manually.:

    wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -
sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/
sudo apt update
sudo apt install adoptopenjdk-8-hotspot  # Java 8 / HotSpot VM
sudo apt install adoptopenjdk-8-openj9   # Java 8 / OpenJ9 VM
sudo apt install adoptopenjdk-11-hotspot # Java 11 / HotSpot VM
sudo apt install adoptopenjdk-11-openj9  # Java 11 / OpenJ9 VM
sudo apt install adoptopenjdk-12-hotspot # Java 12 / HotSpot VM
sudo apt install adoptopenjdk-12-openj9  # Java 12 / OpenJ9 VM
sudo apt install adoptopenjdk-13-hotspot # Java 13 / HotSpot VM
sudo apt install adoptopenjdk-13-openj9  # Java 13 / OpenJ9 VM

    You can switch between e.g. OpenJDK, AdoptOpenJDK and Adoptium by using the following command.:

    sudo update-alternatives --config java
