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 macbooks 硬盘驱动器已满并且 osx 抛出有关内存问题的消息，并且它将删除一些文件（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。

看起来像是某种 Unix/OS X 权限问题。当 Searchable/Lucene 启动并尝试创建索引时，它所做的第一件事就是在索引目录中创建一个锁定文件。从您的堆栈跟踪来看，这似乎是失败的原因。

该Searchable.groovy文件是定义索引路径的位置；它可能已在environment块中被覆盖，甚至可能在Config.groovy.

grails run-app以您的用户身份运行 Grails，因此问题与以不同用户身份运行的 Tomcat 没有任何关系。

根据默认的conf文件

/**
 * 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），我会看看

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

我的 tomcat 安装在 ${user.home}/.grails/projects/${app.name}/searchable-index ，请记住 tomcat 进程可能在与您不同的用户下运行，所以我运行了“sudo nautilus “能够看到它
