eclipse错误存在于必需的项目中，但编辑器没有显示错误

[英]eclipse errors exist in required projects but editor shows no errors

原文 2013-10-28 07:22:18 5 1 java/ eclipse

I use eclipse to code in java. 我使用eclipse来编写java代码。 My code was running perfectly fine. 我的代码运行得很好。 Finally, i deleted some files which were not needed from my drive. 最后，我删除了一些我的驱动器不需要的文件。

Right now, I have the source file and the compiled .class files in the correct folders. 现在，我将源文件和已编译的.class文件放在正确的文件夹中。 Also, although I initially had multiple .java files, I am 100% sure that the one I need is there and also that it doesn't need anything from any other thing. 此外，虽然我最初有多个.java文件，但我100％确定我需要的那个，并且它不需要任何其他任何东西。 All the imports (i import only from standard libraries) are showing no error. 所有导入（我只从标准库导入）都没有显示错误。

The problem is that when i make any changes in my .java file, and save it, it does get saved but when I execute the code, it runs just like the old version, ie the changes are not reflected in the output. 问题是，当我在.java文件中进行任何更改并保存它时，它会被保存，但是当我执行代码时，它就像旧版本一样运行，即更改不会反映在输出中。 Also, on clicking 'run', eclipse gives a warning that 'errors exist in required projects' although the editor shows none. 此外，在点击“运行”时，eclipse会发出警告，即“所需项目中存在错误”，尽管编辑器没有显示。

Whats going wrong ? 什么出错了？ Please help. 请帮忙。

Okay got it....I had added some external jars to my project. 好的....我在我的项目中添加了一些外部罐子。 Later, when I realised that they were not needed anymore, i deleted them from my hard disk. 后来，当我意识到不再需要它们时，我将它们从我的硬盘中删除了。 However, the build path contained their names too among the other libraries (and displayed "missing" after that). 但是，构建路径在其他库中也包含它们的名称（之后显示为“缺失”）。 I removed them and its working fine. 我删除了它们并且工作正常。
