我试图让 Elasticsearch 在我的 Grails 项目中工作。我正在使用此处记录的 Elasticsearch 中的 Java Rest 高级客户端 [ https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.3/java-rest-high-getting-started-maven.html]。我正在使用 Elasticsearch 6.3.2 版本、Java 8、Grails 2.4.4
我创建了一个服务类并在文件开头添加了一个导入语句。例如：import org.elasticsearch.ElasticsearchException
而且，当我启动 Grails 时，我收到以下错误。但是，如果我删除该导入语句，则应用程序运行良好。那么，导入中发生了什么？

那么，有人可以帮助我了解这里发生了什么吗？
谢谢。
