Java eclipse无法识别导入组织。阿帕奇。已随maven导入的poi包
我正试图用ApachePOI在java中创建一个excel,我正在使用SpringBoot和thymeleaf,我已经在pom中导入了依赖项。xml文件并在我的eclipse中更新它,依赖项在我的项目中,当我运行命令mvn clean install时,一切似乎都正常,但是当将它导入到我的java类时,它找不到它,我已经尝试更改apache poi库的版本,但它不起作用。我在这里留下一些参考数据:
this is the class that I want to inport
eclipse does not recognize the jara apache-poi class
这是我的pom代码。xml:

你认为问题出在哪里?我真的很感谢你的帮助。
# 1 楼答案
我将回答我自己的问题,以防将来有人发现它有用:
我不知道是什么
也就是说,现在我看到这个范围表示编译时不需要依赖项,而是执行时需要依赖项。它位于运行时和测试类路径中,但不在编译类路径中
所以解决方法就是去掉这个标签
# 2 楼答案
您不需要添加ApachePOI的依赖项范围。 从这里检查
https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml/4.1.2
我在gradle中使用它们,默认情况下它们的作用域是编译时
https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml/4.1.2
