JDT Core/Java8

This page summarizes the work that is being done to add Java(tm) 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

  • JSR 335 (Lambda expressions)
  • JSR 308 (Type annotations)

What need to be done


Current status



  • The following lines should be added in all headers of modified files for Java(tm) 7 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.

What to do to set up the IDE

  • You need to install a JDK8 build as an installed JRE in order to run the tests using the JavaSE-1.8 Execution Environment.


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 forums or Bugzilla.
