grails - 使用 grails 可搜索插件的 apache lucene 索引文件的默认路径在哪里？

Question

我在我的 grails 1.3.7 项目中使用可搜索插件。我的项目运行良好，直到我的 macbook 硬盘驱动器已满并且 osx 抛出了一条关于内存问题的消息，它会删除一些文件(tmp 等)(之后我删除了一些电影并获得了超过 10GB 的可用空间)。我没有更改源代码，但是当我现在启动我的 grails 应用程序时，出现以下异常:

我认为文件系统中的 lucene 索引有问题，但我在哪里可以找到它？ lucene 索引文件夹或文件存储在哪里？我没有更改插件配置。

Answer 1

根据default conf file

/**
 * The location of the Compass index
 *
 * Examples: "/home/app/compassindex", "ram://app-index" or null to use the default
 *
 * The default is "${user.home}/.grails/projects/${app.name}/searchable-index/${grails.env}"
 */

所以除非你改变了它(你说你没有)，否则我会看看

~/.grails/projects/${app.name}/searchable-index/${grails.env}
