I have this app for XML and flatfile generation in the src folder and I have the jarFiles in Jarfiles folder.我在 src 文件夹中有这个用于 XML 和平面文件生成的应用程序，我在 Jarfiles 文件夹中有 jarFiles。

I was trying to compile my java file and I get this error: package org.apache.poi.hssf.usermodel does not exist , I am importing this in my java file and have the jar file in the src folder.我试图编译我的 java 文件，我得到这个错误： package org.apache.poi.hssf.usermodel does not exist ，我将它导入到我的 java 文件中，并将 jar 文件放在 src 文件夹中。 How can I fix this problem?我该如何解决这个问题？

Update: I tried to include the jarfiles as the answer indicated with this line in cmd javac -cp "jarFiles/*" Xls_Reader.java , it seems that I am still having the same error更新：我试图在 cmd javac -cp "jarFiles/*" Xls_Reader.java中包含 jarfiles 作为这一行指示的答案，看来我仍然有同样的错误

As it seems that you are not using a build tool like Maven or Gradle, you have to make the jar part of your classpath (to get instructions on how to do that, see https://stackoverflow.com/a/49515986/16342635 .由于您似乎没有使用 Maven 或 Gradle 之类的构建工具，因此您必须将 jar 作为类路径的一部分（要获取有关如何执行此操作的说明，请参阅https://stackoverflow.com/a/49515986/16342635 .

However, I would recommend getting familiar with a build tool like Maven and to manage your dependencies (your "jar files") with that.但是，我建议您熟悉 Maven 之类的构建工具并使用它来管理您的依赖项（您的“jar 文件”）。
