Building

Basic steps:

  1. Install OpenJDK 17 (exactly this version).
  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.

See Contributing Guide for details.
