I’ve been using .sdkman to easily install JDKs for a while now, and one thing that bothers me about Eclipse is that it doesn’t automatically detect the JDKs that .sdkman manages.
JRE Discovery
So I wrote the JRE Discovery plugin for Eclipse. It’s a simple plugin that automatically detects the JREs that Java managers install, and configures them in Eclipse. It currently detects JREs managed by :
Managed JREs will be automatically discovered on Eclipse startup, or, while running, when added by their respective Java managers.
Automatic detection can be disabled from the JRE Discovery preference page:

Installation
JRE Discovery is available in the Eclipse Marketplace. Drag the following button to your running Eclipse workspace. (⚠️ Requires the Eclipse Marketplace Client)
Alternatively, in Eclipse:
- open
Help>Install New Software... - work with:
https://github.com/sidespin/jre-discovery/releases/download/latest/ - expand the category and select the JRE Discovery Feature
- proceed with the installation
- restart Eclipse
