grails - grails应用程序与可搜索插件的独立应用程序抛出NoClassDefFoundError

Question

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，一切都可以正常运行，而且我也可以将WAR文件部署到tomcat 7实例，而不会出现任何问题。但是，如果使用grails build-standalone构建独立的JAR，则由于以下ClassNotFoundException导致无法启动JAR:

为了表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

我已经尝试过从默认的tomcat 8切换到tomcat 7和 jetty (相同的结果)。我也尝试了Java 7和Java 8，两者的结果相同。

Answer 1

这是Burt Beckwith在我的错误报告中给出的答案:

Sorry to do this, but I can't spend any time working on this issue. You shouldn't be using the searchable plugin - it only works with Hibernate 3, and it doesn't scale because it uses a local file-based index. It's based on Compass (http://sourceforge.net/projects/compass/files/compass/), which was last updated in 2009. ElasticSearch is a much better option - see http://thedudeabides.com/articles/the_future_of_compass/
