install-jdk

The install-jdk library is a Python package that simplifies the process of installing OpenJDK on Windows, macOS, Linux and other supported operating systems, saving time and effort. install-jdk is a useful tool for users, developers, and system administrators who need to set up Java development environment or runtime in an automated and repeatedable fashion.

install-jdk has no third-party dependencies and depends solely on the standard libraries found in Python3. This means that you can easily install and use the library without having to install any additional dependencies.

install-jdk aims to provide as many options as possible to install an OpenJDK Java version across a wide array of operating systems and architectures. Please see each vendors OpenJDK documentation to see what operating systems and architectures they support.

Supported OpenJDK Build Vendors

OpenJDK Build	Status	Vendor Tags	Vendor Documentation	install-jdk Documentation	Source Code
Adoptium (default)	Implemented	Adoptium, Temurin, AdoptOpenJDK, eclipse	Adoptium	Adoptium Build Client docs	Adoptium Build Client src
Corretto	Implemented	Corretto, Amazon, AWS	Corretto	Corretto Build Client docs	Corretto Build Client src

install-jdk will do its best to detect the operating system and architecture that it is running on. Currently is able to detect:

• Operating Systems

  • Windows
  • Linux
  • MacOS
  • AIX

• Architecture

  • arm
  • aarch64
  • ppc64
  • x64
  • x86

Installation

To install the install-jdk library, simply run the following command:

pip install install-jdk

Usage

To use the install-jdk library, import it into your Python code:

import jdk

The library provides an install function, which takes the following parameters:

• version - The major version of the Java OpenJDK build to install (e.g. 8, 11, 17, etc.).
• operating_system - The target operating system. If not specified, will use the user's detected operating system if possible.
• arch - The target architecure. If not specified, will use the user's detected architecture if possible.
• impl - The Java implementation to use. Currently only supports HOTSPOT and dependent on the OpenJDK Build Vendor.
• jre - A boolean value indicating that the Java Runtime Environment should be installed. Defaults to false, which will install the Java Development Kit.
• path - The location to install the downloaded OpenJDK build. If not specified, will install into $HOME/.jdk/<VERSION> for the Java Development Kit and $HOME/.jre/<VERSION> for the Java Runtime Environment.
• vendor - The vendor to download the OpenJDK build from. If not specified, defaults to Adoptium. This is a named argument so must be provided like vendor='Corretto'. Please see the list of Supported OpenJDK Build Vendors

Here are some example code snippet:

jdk.install('11')
# Platform dependent install of Java JDK 11 into $HOME/.jdk/<VERSION>

jdk.install('11', jre=True)
# Platform dependent install of Java JRE 11 into $HOME/.jre/<VERSION>

jdk.install('17', vendor='Corretto')
# Installs a Corretto build of Java 17 JDK. Defualt vendor is Adoptium

jdk.install('17', vendor='Corretto', path='/usr/local/jdk')
# Installs a Corretto build of Java 17 JDK into /usr/local/jdk

The library also has a get_download_url function that returns the URL for the given version, it takes the following parameters:

• version - The major version of the Java OpenJDK build to install (e.g. 8, 11, 17, etc.).
• operating_system - The target operating system. If not specified, will use the user's detected operating system if possible.
• arch - The target architecure. If not specified, will use the user's detected architecture if possible.
• impl - The Java implementation to use. Currently only supports HOTSPOT and dependent on the OpenJDK Build Vendor.
• jre - A boolean value indicating that the Java Runtime Environment should be installed. Defaults to false, which will install the Java Development Kit.
• vendor - The vendor to download the OpenJDK build from. If not specified, defaults to Adoptium. This is a named argument so must be provided like vendor='Corretto'. Please see the list of Supported OpenJDK Build Vendors

Here are some example code snippets:

from jdk.enums import OperatingSystem, Architecture

download_url = jdk.get_download_url('17', jre=True)
print(download_url)
# Obtains the platform dependent JRE download url

download_url = jdk.get_download_url('17', operating_system=OperatingSystem.LINUX, arch=Architecure.AARCH64, vendor='Corretto')
print(download_url)
# Obtains OpenJDK 17 from Corretto for Linux running on aarch64

The library has a download function that will download the requested version and returns back the path to where it was downloaded. This function does not currently support overriding the default download path which is the operating systems specific TMP directory. It takes the following parameters.

• download_url - The URL to the file to be downloaded. Defaults to None.
  • • version - Required when download_version is None and must be provided as a named parameter. The major version of the Java OpenJDK build to install (e.g. 8, 11, 17, etc.).
• operating_system - Must be provided as a named parameter. The target operating system. If not specified, will use the user's detected operating system if possible.
• arch - Must be provided as a named parameter. The target architecure. If not specified, will use the user's detected architecture if possible.
• impl - Must be provided as a named parameter. The Java implementation to use. Currently only supports HOTSPOT and dependent on the OpenJDK Build Vendor.
• jre - Must be provided as a named parameter. A boolean value indicating that the Java Runtime Environment should be installed. Defaults to false, which will install the Java Development Kit.
• vendor - The vendor to download the OpenJDK build from. If not specified, defaults to Adoptium. This is a named argument so must be provided like vendor='Corretto'. Please see the list of Supported OpenJDK Build Vendors

Here are some example code snippets:

from jdk.enums import OperatingSystem, Architecture

download_file = jdk.download('https://api.adoptium.net/v3/binary/latest/17/ga/windows/x64/jdk/hotspot/normal/eclipse')
print(download_file)
# Downloads the requested file and returns back the TMP locations it was stored in.

download_file = jdk.download(version='17', operating_system=OperatingSystem.LINUX, arch=Architecure.AARCH64, vendor='Corretto')
print(download_file)
# Downloads the a Linux aarch64 build of Java 17 from Corretto and returns back the TMP location it was stored in.

The library also provided two helper properties that can be used to see what it detected as the user's operating system and architecture.

print(jdk.OS)
print(jdk.ARCH)

The install-jdk library uses OpenJDK builds, and is created and maintained by jyksnw.

This was originally a port of the GitHub Action installjdk but has morphed into something much more.
