JFrame受限制，因为对所需库的限制 [英] JFrame Restricted due to restriction on required library

问题描述

我正在eclipse中创建一个新的Java项目.唯一的问题是，在出现如下错误信息之前，我什至没有得到5行信息:

I am making a new Java project in eclipse. The only problem is that I didn't even get five lines in before I got an error that reads:

Access Restriction: The type JFrame is not accessible due to restriction on 
required library C:\Program Files\Java\jre8\lib\rt.jar

如何解决此问题?如果有人已经问过类似的问题，请原谅我.我还是一个初学者.

How do I fix this issue? Please forgive me if someone already asked a similar question. I am still a beginner.

推荐答案

尝试删除Java系统库并将其读取到您的项目中:

Try removing and readding the Java System Library to your project:

项目属性->构建路径->库->删除，然后添加库-> JRE系统库

Project Properties -> Build Path -> Libraries -> Remove , and then Add Library -> JRE System Library

在删除库后尝试关闭并重新打开对话框

Try closing and reopening the Dialog after removing the the Library
