I know there is a Java 9 Support for Oxygen plugin , but does anyone know when Eclipse supports Java 9 natively? I have looked at the project website and blog ( eclipse ) but cannot find any information.
Support for JDK 9 and JUnit 5 will ship with Eclipse Oxygen.1a, October 11, 2017 .
See also the announcement on the Eclipse mailing list [cross-project-issues-dev] .
Update . The above version has been released (see my video, which shows native support for Java 9 and JUnit 5 Eclipse Java IDE Oxygen.1a ).
If you are updating Eclipse Oxygen using Java 9 BETA support for Oxygen, manually uninstall Java 9 BETA (see Eclipse Error 526065 ).
