Apache Lucene - Downloads and Releases

Information on Lucene Java Downloads and Releases.

Official Release

Official releases are usually created when the developers feel there are sufficient changes, improvements and bug fixes to warrant a release. Due to the voluntary nature of Lucene, no releases are scheduled in advance. System Requirements are detailed here.

Both binary and source releases are available for download from the Apache Mirrors

The lucene-VERSION.zip (where VERSION is the version number of the release, i.e. 2.0.0) file contains the lucene-core jar file, html documentation, a demo application (see Getting Started) and various jar files containing contributed code.
If all you need is the core jar file you can download that separately.
