Action class not found on jar file, but works on Eclipse, how is that?

Elastic Stack Elasticsearch
1

I am using Spring Boot Starter to persist data to Elasticsearch but when I build the jar file it says there is a missing class.

What´s wrong? I am using 7.5.2 version.

My pom.xml dependency is...

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>
<dependency>
	<groupId>org.elasticsearch.client</groupId>
	<artifactId>elasticsearch-rest-client</artifactId>
</dependency>

Console error when I try:

% java -jar javapp.jar

Actually looking inside Maven Dependencies jars I can't find that class, but the strange is when I run on Eclipse everything works.

When using springboot with
elasticsearch, you need to be explicit with some transitive dependencies as SpringBoot declares a version 6.4...

Basically you can put this in your pom.xml:

<properties>
  <elasticsearch.version>7.5.2<elasticsearch.version>
</properties>

See documentation here: https://docs.spring.io/spring-boot/docs/current/reference/html/howto-build.html#howto-customize-dependency-versions

Thanks a lot.

Actually I removed the version number from properties and Spring used version 6.8.6, problem solved.

In my mind that doesn't make sense because it should be pointing to the newest version since the Elasticsearch is 7.5.2
