Eclipse 4.3开普勒缺少JRE系统库 [英] Eclipse 4.3 Kepler missing JRE system library

问题描述

我对Java非常新奇（目前约有一个星期的经验）。我在PC上的旧版eclipse Juno中做了大量简单的程序。我将所有文件复制到闪存驱动器上，并将它们放入我的Mac笔记本电脑上的eclipse开普勒工作区。现在，每一行代码都无法识别，并且所有项目中的JRE系统库文件夹都已经被删除了。我不知道如何解决这个问题，如果有人会帮助我的noob自我，我会很乐意。谢谢！

解决方案

你必须在eclipse中从mac配置jre。你会发现它在窗口偏好下搜索jre。
此后，在eclipse项目中，您可以使用新配置的jre（项目属性 - Java构建路径）

希望这有帮助。

I am extremely new to java (about one week of experience at the moment). I have made a fair amount of simple programs in an older version of eclipse Juno on a PC. I copied all of the files onto a flash drive and put them into the workspace of eclipse kepler on my mac laptop. Now every single line of code is unrecognized and the JRE system library folder is gone from all of the projects. I am not sure how to fix this and I would love if someone will help my noob self at this. Thanks!

解决方案

You have to configure the jre from your mac in eclipse. You find it under window preferences and search for jre. After that, in your eclipse project you can use the new configured jre (project properties - Java Build Path)

Hope this helps.
