Have a look at <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=380190" rel="noreferrer">this bug report</a> from time to time for progress on Java 8 in Eclipse's JDT.

EDIT: For Kepler you need SR2 (4.3.2) and the Java 8 <a href="https://wiki.eclipse.org/JDT/Eclipse_Java_8_Support_For_Kepler" rel="noreferrer">feature patch</a>. Starting with I20140318-0830 all <a href="http://download.eclipse.org/eclipse/downloads/" rel="noreferrer">Luna (4.4) builds</a> contain support for Java 8 "out-of-the-box". The final version of Eclipse Luna (4.4) will be released at the end of June 2014.

I am assuming that you have installed Java 8, JRE 8 and configured them (setting class paths etc.). 
Follow the steps.
Go to Help->Eclipse market place
In the search box type "java 8 kepler"
The first link that appears is Java 8 support for Kepler SR2
select it and install it.
It will take a few minutes.
You may need to restart Eclipse after completion.

The problem is that the version of Kepler your using might not have the support for Java8. You can either install the Java8 Patch from market place if your using SR2 version 

or

You can directly download Eclipse Kepler SR2 from <a href="http://www.eclipse.org/downloads/packages/release/kepler/sr2" rel="nofollow">here</a>, which comes with default support for Java8

I want to start using Java 8 with Eclipse but I don't know how to install it - I can't find any tutorials on it. I am using Eclipse Kepler and have added a JRE for JDK 8 to the IDE but it won't let me continue to create the project because of a compliance problem with the JRE versions. How can I use Java 8 with the Eclipse Kepler IDE?

我想开始在Eclipse中使用Java 8，但是我不知道如何安装它--我找不到任何关于它的教程。我正在使用Eclipse Kepler，并且已经在IDE中添加了一个用于JDK 8的JRE，但是由于JRE版本的兼容性问题，它不允许我继续创建该项目。如何将Java 8与Eclipse Kepler IDE结合使用？
