Quickly download portable JVMs/JREs

The remote ojob.io/java/download job downloads and repackages Java distributions. It is maintained outside the four repositories in the documentation baseline. Consult its current help before use; available builds and default versions can change.

For the current OpenAF source baseline, request Java 21 or later explicitly:

ojob ojob.io/java/download version=21 os=linux arch=x64 type=jre

The job writes a runtime archive such as jre.tgz in the working directory. Extract it in a separate directory and check the executable:

tar xzf jre.tgz
jre/bin/java -version

Download a JDK instead of a JRE

ojob ojob.io/java/download version=21 os=linux arch=x64 type=jdk

Download a different version, a different architecture and/or a different operating system

For a Java 21 JDK on an Apple Silicon Mac:

ojob ojob.io/java/download type=jdk arch=aarch64 os=mac version=21

The target platform describes where the archive will run, which may differ from the machine downloading it.

Listing available options

ojob ojob.io/java/download version=21 list=true

Use a combination returned by the current catalog. Archive sizes, release numbers and available combinations depend on the provider. See updating OpenAF’s JVM to switch an existing installation.
