For a details of release notes see GitHub Release


This release is still work in progress under master branch!

Most Significant Changes This Release:

  • Quartz 2.4.0 now requires minimum Java version of Java 8

  • Quartz build system moved to Gradle

  • 3rd party libraries (slf4j, log4j, Hikari) upgraded to more recent versions

  • Maven POMs generated from gradle declare 3rd party dependencies as "runtime" scope

  • Removal of old TerracottaJobStore

  • "NativeJob" class removed from "quartz-jobs" artifact. This resolves security concerns related to code execution. While it is possible to safely use this Job class, it is a risk for users that don’t engage some thought. If you wish to still use this job or something like it, the source code for it can now be found as "example15".

  • Example programs can now simply be executed via gradle. See the "exmaples_guide.txt" file in the examples folder of the quartz repository for full description and info.
