Installing Java Modules

System Compatibility

Java modules are regularly built and tested on macOS and Linux distributions.

Java Compatibility

Java modules are currently compatible with Java 8 / 9 / 10 / 11.

Installing from Maven

By default, Maven will download from the central repository: https://repo.maven.apache.org/maven2/org/apache/arrow/

Configure your pom.xml with the Java modules needed, for example: arrow-memory-netty, arrow-format, and arrow-vector.

Installing Nightly Packages

Warning

These packages are not official releases. Use them at your own risk.

Arrow nightly builds are uploaded to GitHub. For example, for 2022/03/01, they can be found at Github Nightly.

To test your code with these artifacts, then configure Maven with:

$ cat ~/.m2/settings.xml
<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.1.0"
