I know that there is a plug-in Java 9 Support for Oxygen but does anyone know when will Eclipse support Java 9 natively? I looked on project website and blog (planet eclipse) but can't find any information.
回答1:
Support for JDK 9 and JUnit 5 will come with Eclipse Oxygen.1a, October 11, 2017.
See also the announcement on the Eclipse [cross-project-issues-dev] mailing list.
Update: The above mentioned version is released (see my video that shows the built-in Java 9 and JUnit 5 support of the Eclipse Java IDE Oxygen.1a).
If you update Eclipse Oxygen with Java 9 BETA Support for Oxygen, uninstall Java 9 BETA manually (see Eclipse bug 526065).
