Online Documentation

This README file only contains basic setup instructions. For more comprehensive documentation, visit:

• Latest Releases: https://lucene.apache.org/core/documentation.html
• Nightly: https://ci-builds.apache.org/job/Lucene/job/Lucene-Artifacts-main/javadoc/
• New contributors should start by reading Contributing Guide
• Build System Documentation: help/
• Migration Guide: lucene/MIGRATE.md

Building

Basic steps:

1. Install OpenJDK 21.
2. Clone Lucene's git repository (or download the source distribution).
3. Run gradle launcher script (gradlew).

We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.
