Revision as of 15:54, 8 November 2012 by Unnamed Poltroon (Talk) (→Setup projects in a runtime workbench)
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
Contents
Java 8 features that are being worked on
- JSR 335 (Lambda expressions)
- JSR 308 (Type annotations)
What needs to be done
- TO BE FILLED
Current status
- TO BE FILLED
IMPORTANT NOTE
- The following lines should 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. *
What to do to set up the IDE
- Checkout the BETA_JAVA8 branch of the following git repositories:
- JDT/Core repository - git://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.git
- You need to install a JDK8 build as an installed JRE in order to run the tests using the JavaSE-1.8 Execution Environment.
- For more information on how to work with git repositories, look at http://wiki.eclipse.org/Platform-releng/Git_Workflows .
- As API Baseline, use 3.8 (or 3.8 RC4 until 3.8 is released).
Configure a project to use Java 8 features
Because JDT/UI does not yet offer the options to configure a project for Java 8, any projects wishing to use Java 8 features should be manually configured by ensuring these lines 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.
