为什么 IntelliJ 给我“包不存在"?错误? [英] Why does IntelliJ give me "Package doesn't exist" error?

问题描述

我正在尝试使用烧烤条码打印库.我已经通过项目结构添加库成功地将库添加到 IntelliJ.然后我导入了包并编写了方法，这没有给我带来任何错误.课程中提供了这些软件包.

I'm trying to use the barbecue barcode printing library. I have successfully added the library to IntelliJ through project structure add library. Then I imported the packages and wrote the methods, which gave me no error. The packages were available in the class.

但是当我编译它给了我错误:

But when I compile it gives me the error:

error: package net.sourceforge.barbecue does not exist

这怎么可能?

我正在 ubuntu 中编码，还有其他地方需要添加库吗?

I'm coding in ubuntu, is there any other place to which I have to add the library?

推荐答案

只是重新导入没有用.以下为我工作.

Just reimport didn't work. Following worked for me.

文件 ->使缓存无效/重新启动

File -> Invalidate Caches /Restart

然后

构建 ->重建项目

这将重新导入 maven 项目.

That will reimport maven project.

注意:您需要使缓存失效并重建项目.
