elasticsearch-rest-high-level-client dependency is not working

Question

it's my first question. I have to using ES rest high level client. my ES server is 6.8.x, so i write my build.gradle file.

compile "org.elasticsearch.client:elasticsearch-rest-high-level-client:6.8.5"

but my project dependency works like below.

• Gradle: org.elasticsearch.client:elasticsearch-rest-client:7.6.2
• Gradle: org.elasticsearch.client:elasticsearch-rest-high-level-client:6.8.5
• Gradle: org.elasticsearch.client:elasticsearch-rest-high-level-client:7.6.2 .. and more ...

why the wrong version 7.6.2 imported?

Answer 1

i got the answer myself.

the spring boot 2.3.x are using Elasticsearch 7.6.2 by dependency management(BOM). https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#preface.versions

the answer is overriding the version in gradle.

ext['elasticsearch.version'] = '6.8.5'

be careful... this is not working.

ext {
        elasticsearch.version = '6.8.5'
}

good!
