My company is using spring framework 4.3.20.RELEASE and maven, now we are going to integrate Elasticsearch. Sadly we cannot use Spring Boot to manage the versions.
How could I find out which Spring Data Elasticsearch pom version is best suited? Is there a version matrix? How would you find out the most compatible version in these situations?
The version matrix for Spring Data Elasticsearch (https://docs.spring.io/spring-data/elasticsearch/docs/4.1.2/reference/html/#preface.versions) does not contain the Spring Core dependencies - I'll have to fix that.
When checking mvnrepository.com I find that Spring 4.3.20.RELEASE is from October 15th 2018 - pretty old.
The last Spring Data release train on Spring 4.3 was Ingalls (https://github.com/spring-projects/spring-data-commons/wiki/Release-Train-Ingalls) and that contained Spring Data Elasticsearch 2.1 which in turn used the Elasticsearch client libraries from Elasticsearch 2.3.3.
I honestly doubt that the Elasticsearch you are using is this old.
I think you first should upgrade you Spring dependency to a current 5 before trying to integrate Spring Data.
