Source-backed version compatibility
Jenkins Java version compatibility. Jenkins weekly 2.585 tests Java 21 and Java 25 in its tagged build configuration, consistent with the Java support policy for weekly releases since 2.545.
Quick answer
Supported and tested versions have compatibility evidence. Recommended and bundled versions describe upstream choices without establishing compatibility. Versions outside the documented coverage are unknown, not necessarily incompatible.
Tested Java versions
Jenkins weekly 2.585 tests Java 21 and Java 25 in its tagged build configuration, consistent with the Java support policy for weekly releases since 2.545.
These runtime requirements apply to controllers, agents, and CLI clients; JDK versions used by jobs and build tools are independent.

Tested Java versions
Jenkins LTS 2.580.1 lists Java 21 and Java 25 as its tested JDK configurations.
The same Java requirement applies to Jenkins controllers, all agent types, CLI clients, and other Jenkins system components.
JDK versions used by jobs and build tools are independent and are not modeled by this entry.
