带有可搜索插件的 grails 应用程序独立应用程序抛出 NoClassDefFoundError答案

【问题标题】：grails app standalone app with searchable plug-in throws NoClassDefFoundError带有可搜索插件的 grails 应用程序独立应用程序抛出 NoClassDefFoundError

【问题描述】：

我正在尝试使用 grails standalone app runner plug-in (v.1.3) 构建一个独立的 grails (v.2.5.0) 应用程序。使用 run-app 和 run-war 一切正常，我还可以将 WAR 文件部署到 tomcat 7 实例而不会出现任何问题。但是，如果我使用 grails build-standalone 构建独立的 JAR，由于以下 ClassNotFoundException，我无法启动 JAR：

为了证明这个问题是可重现的，我在 github 上准备了一个最小的例子：

https://github.com/mlist/grails-standalone-search-bug

我在以下位置创建了一个错误报告： https://jira.grails.org/browse/GPSTANDALONE-22

我已经尝试从默认的 tomcat 8 切换到 tomcat 7 和码头（结果相同）。我还尝试了 java 7 和 java 8，结果都一样。

【问题讨论】：

正如this response 中所报告的那样，“您不应该使用可搜索插件 - 它仅适用于 Hibernate 3，并且无法扩展，因为它使用基于本地文件的索引”。所以问题是插件不直接支持这种执行模式：你为什么不用完整的解释来回答自己。这样，这个问题将来可能对其他人有用。
你说得对，我应该添加 Burt 的回复。

【解决方案1】：

这是 Burt Beckwith 在我的错误报告中给出的答案：

很抱歉这样做，但我不能花任何时间处理这个问题。您不应该使用可搜索插件 - 它仅适用于 Hibernate 3，它不能扩展，因为它使用基于本地文件的指数。它基于指南针 (http://sourceforge.net/projects/compass/files/compass/)，这是最后一次更新是在 2009 年。ElasticSearch 是一个更好的选择 - 请参阅 http://thedudeabides.com/articles/the_future_of_compass/
