软件包不存在-Eclipse [英] Package Does Not Exist - Eclipse

问题描述

我对Java还是陌生的，因此，如果它有一个简单的解决方案，请原谅我(不过我希望如此).在尝试导入com.abc时，我已经在eclipse中将以前编码的.java类文件添加到了我现有的项目中.和 ctrl + space 甚至显示了这些包和类.

I am new to Java so please forgive me if this has a simple solution (and I hope so though). I have added previously coded .java class files to my existing project in eclipse, while trying to import com.abc. and ctrl+space it even shows these packages and classes.

但是，当我尝试编译时，它说包xxx不存在".我已经花了数小时研究这个问题，但是大多数解决方案都集中在.JAR文件上，但是我没有jar文件.我什至尝试创建一个.JAR文件，然后导入，但是我认为我无法成功做到这一点.

However when I try to compile it says "package xxx does not exist". I've spent hours researching on this but most of the solutions focus on .JAR files and I don't have a jar file. I even tried creating a .JAR file and then importing but I think I couldn't manage to success that.

我真的需要帮助，谢谢您的帮助.问候

I really need help about this and thanks for your help. Regards
