# System Requirements

Apache Lucene runs on Java 8 or greater.

For HiDPI graphics on Windows/Linux, Java 11 or greater is recommended to run the bundled GUI application Luke.

It is also recommended to always use the latest update version of your Java VM, because bugs may affect Lucene. An overview of known JVM bugs can be found on http://wiki.apache.org/lucene-java/JavaBugs

With all Java versions it is strongly recommended to not use experimental `-XX` JVM options.

CPU, disk and memory requirements are based on the many choices made in implementing Lucene (document size, number of documents, and number of hits retrieved to name a few). The benchmarks page has some information related to performance on particular platforms.

To build Apache Lucene from source, refer to the `BUILD.txt` file in the distribution directory.
