Java 指南针索引创建

我会犯这样的错误

Failed to open Lucene reader/searcher; nested exception is  
org.compass.core.engine.SearchEngineException:  
Failed to open index searcher for sub-index [meta]; nested exception is 
java.io.FileNotFoundException:  
/home/test/testrun/target/compass/project/index/meta/segments_dia  
(No such file or directory).

您是否检查了异常中的路径

/home/test/testrun/target/compass/project/index/meta/segments\u dia

如果找不到这样的目录，则引发此异常。

显示代码相关代码在java中的含义或对配置文件的需要代码只引发异常。但为什么会发生此异常。应用程序运行良好，但突然出现上述错误。如何查找和解决
