Revision as of 02:44, 13 September 2013

This page summarizes the work that is being done to add Java™ 8 support into Eclipse. As of now JSR 335 (Lambda expressions) and JSR 308 (Type annotations) are being planned

Java 8 features that are being worked on


What needs to be done

  • TO BE FILLED


Current status

Updates are filed in the top level bug [380190 - Add support for Java SE 8]

IMPORTANT NOTE

  • The following lines must be added in all headers of modified files for Java™ 8 implementation:
 * This is an implementation of an early-draft specification developed under the Java
 * Community Process (JCP) and is made available for testing and evaluation purposes
 * only. The code is not compatible with any specification of the JCP.
 *

  • Use the following @since tag on all newly added members: "3.9 BETA_JAVA8"


What to do to set up the IDE

  • You need to install a JDK 8 build as an installed JRE in order to run the tests using the JavaSE-1.8 Execution Environment.
  • If you are going to be running Ant builds (stand-alone or as project builders) using the 1.8 javac target, you should read the following wiki: Ant / Java 8.


Configure a project to use Java 8 features

If you have JDT UI from the BETA_JAVA8 branch, you can simply set the compliance to 1.8. Otherwise you have to manually set the following properties in <project>/.settings/org.eclipse.jdt.core.prefs:

org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8
org.eclipse.jdt.core.compiler.compliance=1.8
org.eclipse.jdt.core.compiler.source=1.8

Disclaimer

This is a work in progress. The contents of the BETA_JAVA8 branch will be updated as the changes are made to the JSR Specification.

If you need any help with this, please contact the JDT/Core team through either the forum or Bugzilla.
