The Eclipse Foundation’s annual release train, featuring simultaneous updates to dozens of projects, has just arrived, featuring preliminary Java 9 support. Called Oxygen, the release train covers 83 projects and includes 71 million lines of code.

Here are the key updates in Oxygen:

• Java 9 support remains in beta stage, because Java 9 itself will not be made available until Java Development Kit 9 ships on September 21. Oxygen’s Java 9 support includes the ability to add the Java Runtime Environment for Java 9 as the installed JRE as well as backing for the Java 9 execution environment. Developers also can create Java and plug-in projects using Java 9 and compile modules that are part of a Java project. Eclipse’s signature Java IDE has been enhanced as well, with improvements to the UI.
• Eclipse Linux Tools 6.0 updates Docker Tools with more security options. This project provides a C/C++ IDE for Linux developers.
• Eclipse PDT (PHP Development Tools) 5.0 supports the 7.1 version of PHP, which offers nullable types and a void return type.
• The Eclipse Sirius 5.0 platform for building domain-specific modeling tools, with usability enhancements.
• Eclipse EGit 4.8.0, offering performance and usability for the Java implementation of Git code management integration for Eclipse.

Focused on open source tools, Eclipse has offered annual release trains every June since 2006, letting developers coordinate upgrades or new releases of multiple projects. Last year’s release train, Neon, offered tools for Docker and JavaScript. June 2018’s release is slated to be called Neon.
