Java™ 8 support for Eclipse is ready, see JDT/Eclipse Java 8 Support For Kepler. This page summarizes the work that was done.

Eclipse Support for Java 8 - Release Schedule

  • Feb 21st 2014: Early Access Release IV: Release candidate 1
    • What is new in this release ?
      • JDT/Core and JDT/APT are already feature complete - This is a bug fix release with numerous defects resolved
  • March 7th 2014 : Release candidate 2
    • Bug fixes
  • March 18th 2014: General availability release (Available - See below for install instructions)

Installation instructions

Starting with I20140318-0830 all our Luna (4.4) builds contain the Eclipse support for Java™ 8. For Kepler SR2 (4.3.2) a feature patch is available. For details go to our downloads page.

Java 8 features ready to be tested (save for some very minor defects)

  • JSR 308 - Type Annotations
  • Default & static methods in interfaces
  • Support for lambda expressions and method/constructor references is substantially in place except in the areas of type inference, lambda serialization and varargs.
  • Support for Java 8 type inference specification.
  • Quick assist support for migrating anonymous classes to lambda expressions and vice versa.
  • Meta data enhancement specification:
    • JEP120: Repeating annotations
    • JEP118: Runtime access to parameter names
  • JSR269 Enhancements for Pluggable Annotation Processor API and javax.lang.model APIs
  • Formatter, code completion, code navigation, search & indexing, reconciler, incremental builder support for all of Java 8
  • Basic IDE enablement for all of Java 8
  • AST/APIs for all of Java 8
  • Serializable lambda support
  • JSR308 type annotations based null analysis (substantially complete - some open issues exist)
  • UI: Basic infrastructure like the Java-related views, Java Compiler compliance settings, Organize Imports, Mark Occurrences, Open Declaration (F3), Edit > Expand Selection To > ..., Content Assist (Ctrl+Space), Formatting, and Source Actions should work correctly in most situations when you start using them with Java 8 constructs.


How to report defects ?

File defect reports [here].
Open work items can be perused [here].

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 compile org.eclipse.jdt.annotation and run the tests using the JavaSE-1.8 Execution Environment.
    • Use the exact name "JavaSE-1.8" for the JRE
  • 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.


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. Please use the early access builds only in a test/evaluation mode and not in the real development environment. If you need any help with this, please contact the JDT/Core team through either the forum or Bugzilla.
