Java 如何在Mac上设置Lucene的以下错误？

我在Mac上设置类路径时遇到问题。下面是我尝试过的代码

首先，我使用终端导出罐子

然后，当我回显类路径时，结果如下

当我尝试使用索引文件时，出现了以下错误

请让我知道上述错误，提前谢谢。我对Lucene Java非常陌生

这是常见的Java类路径问题，与lucene或mac无关

试试这个

1) Create lib folder and move all your lucene jars to lib
    - lets say your project has two folders now lib and src, lib has all jars and src has yourJavaFile.java 

2) Run below commands for compilation and execution from your src
   - javac -cp ".:../lib/*" yourJavaFile.java
   - java -cp ".:../lib/*" yourJavaFile
