Eclipse 开普勒 Java 8

Eclipse Kepler Java 8

提问by Liam Potter

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 并在 IDE 中添加了 JDK 8 的 JRE，但由于 JRE 版本的合规性问题，它不会让我继续创建项目。如何在 Eclipse Kepler IDE 中使用 Java 8？

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.

我假设您已经安装了 Java 8、JRE 8 并配置了它们（设置类路径等）。按照步骤。转到 Help->Eclipse market place 在搜索框中输入“java 8 kepler” 出现的第一个链接是 Java 8 support for Kepler SR2 选择它并安装它。这将需要几分钟。完成后您可能需要重新启动 Eclipse。

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

问题是您使用的 Kepler 版本可能不支持 Java8。如果您使用的是 SR2 版本，则可以从市场安装 Java8 补丁

or

或者

You can directly download Eclipse Kepler SR2 from here, which comes with default support for Java8

您可以直接从这里下载 Eclipse Kepler SR2 ，它默认支持 Java8
