Adding Java 9 support in Eclipse

Java 9 is supposed to be launched in June 2017 but we can still download it from Oracle’s website and start playing around it.

If you use Eclipse as your Java development IDE, you won’t be able to add Java 9 as one of the installed JDK. You will get this error  as Eclipse won’t be able to recognize the JDK 9 directory


But fortunately, Eclipse team has released a patch for this. To apply it follow these steps:


The feature patch can be installed from the Eclipse Marketplace with the following steps:

  • Make sure the Marketplace client is installed (this is the case if you use an EPP)
  • Select “Help > Eclipse Marketplace…”
  • Enter “Java 9 support” in the search box and click on “Go”
  • Install Eclipse Java 9 Support (BETA) for Mars

This installation can take few minutes. Once it is done you will be able to add JDK 9 library to your projects
