推荐答案

我在Windows 7上的Eclipse中也遇到了这个问题.解决方法是 转到项目->右键单击->选择属性->项目构面->修改所用JDK版本的Java版本. 请注意，如果项目的JDK版本更高，例如1.5，而您的项目设置为jdk 1.4，则它将无法正常工作. 反之亦然.

I had this problem in Eclipse on Windows 7 as well. The solution is Go to Project-> right Click-> Select Properties -> project Facets -> modify the java version for your JDK version you are using. Please note, if the JDK version of the project is higher, say, 1.5 and your project setting is jdk 1.4, then it will not work. Vice versa will work.
