How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

• Latest stable OpenJDK 8
• Latest stable Apache Maven
• If you are on Linux or MacOS, you need additional development packages installed on your system, because you’ll build the native transport.

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+ / 4.1+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.1 resides in the branch ‘3.9’ and the branch ‘4.1’ respectively.

Usage with JDK 9+

You can read the Modular Netty guide to learn more about using Netty with the Java Platform Module System, the guide
contains a user section and a developer section for Netty contributors.
