Java 中的 ElasticSearch 库无法找到 AggregationBuilders.sum 方法

Question

我正在尝试在java中使用ElasticSearch的AggregationBuilders api来查找总和聚合。但是在使用使用此(AggregationBuilders.sum(((方法的服务时，它会给出以下错误：

java.lang.NoSuchMethodError:org.elasticsearch.search.aggregations.;

这是我的pom.xml文件

到目前为止，我已经尝试通过清理.m2并再次运行全新安装来尝试，但仍然会出现此错误。 任何帮助将不胜感激：

PS ：更改pom后，我可以停止安装elasticsearch 6.5，但6.4.3仍在安装中。我只想要 7.2 版本。知道如何找到导致安装其他版本的依赖项

这是聚合器项目的pom：

Answer 1

Spring Data Elasticsearch3.2 不适用于 Elasticsearch 7;3.2.0.GA 使用 Elasticsearch 6.8。

对Easticsearch 7的支持和适应在现在的主分支中，该分支将在以后成为版本4
