There are some license constraints which should be taken into account while using this plugin. If an external download is needed due to any reason, AdoptOpenJDK Plugin might be used instead of this plugin. The recommended 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. It could happen because Oracle's website change or even if Oracle bans our downloads due to excessive bandwidth or whatever other reason). As it relies on the Oracle's website to do the job, it's highly likely to stop working. We want to warn that this plugin is NOT a good practice for production environments.

Before version 1.3 the plugin was named as 'JDK Tool Plugin', but it was renamed later to reflect what it actually does. The installer provided by the plugin used to be a part of the Jenkins core before it was detached to a separate plugin in Jenkins 2.112. This plugin provides a tool installer for installing Oracle Java SE Development Kit in Jenkins.
