Provides an installer for the JDK tool that downloads the Eclipse Temurin:tm: build based upon OpenJDK from the Adoptium Working Group.
We want to warn that this plugin is NOT a good practice for production environments. As it relies on Adoptium's website to do the job, it's highly likely to stop working. It could happen because Adoptium's website changes or even if Adoptium bans our downloads due to excessive bandwidth usage or some other reason. Currently Adoptium is using GitHub for hosting release archives and GitHub could also stop working due to similar reasons.
The recommended and preferred approach is to download the JDK distribution using other installers, for example downloading it from a well known URL (preferably hosted on your own network) with ZIP Tool Installer, having it pre-installed in agent docker images, or executing a script to do the job.
Configure plugin with Configuration as Code
The configuration as code plugin allows administrators to automate Jenkins configuration. The sample configuration below defines tool installers based on agent labels, and uses
- locally hosted Java installers for Linux and Windows agents (assuming local domain in
example.com) - locally installed Java on agents with the
Alpinelabel - locally installed Java on agents with the
cloudlabel - locally installed Java on agents with the
freebsdlabel
If none of those installers are selected, then as a fallback, the agent will download the specified Java version from the Eclipse Temurin:tm: project.
The example shows the preference to first use locally available zip files and local installations of the JDK. The JDK will be downloaded from the Eclipse Temurin:tm: project only in cases where the local installation is not available or does not apply.
