Elasticsearch third arty dependency in AEM

Avatar

Level 3

I am having some problems using elasticsearch-rest-high-level-client dependency in my project.

According to Elasticsearch documentation only this should be included:

<dependency>
  <groupId>org.elasticsearch.client</groupId>
  <artifactId>elasticsearch-rest-high-level-client</artifactId>
  <version>7.4.0</version>
</dependency>

However, there were many NoClassDefinitionFound errors, so I embed the package inside maven-bundle-plugin. I realized that no transitive dependencies are included (altho I have   <Embed-Transitive>true</Embed-Transitive>)
so I've added many of them like this:

<plugin>
  <groupId>org.apache.felix</groupId>
  <artifactId>maven-bundle-plugin</artifactId>
  <extensions>true</extensions>
  <configuration>
  <instructions>
  <Embed-Dependency>org.apache.servicemix.bundles.solr-solrj, noggit,

  elasticsearch-rest-high-level-client,

  elasticsearch,

  elasticsearch-core,

  elasticsearch-rest-client,

  elasticsearch-x-content,

  elasticsearch-core,

  elasticsearch-secure-sm,

  rank-eval-client,

  lang-mustache-client,

  httpasyncclient,

  lucene-core;

   </Embed-Dependency>
  <Embed-Transitive>true</Embed-Transitive>
  <Embed-Directory>OSGI-INF/lib</Embed-Directory>
  <Export-Package>we.retail.core.model*</Export-Package>
  <Import-Package>
   *;resolution:=optional;

   </Import-Package>
  <Private-Package>
   we.retail.core*

   </Private-Package>
  <Sling-Model-Packages>
   we.retail.core.model

   </Sling-Model-Packages>
  <_fixupmessages>"Classes found in the wrong directory";is:=warning</_fixupmessages>
  </instructions>
  </configuration>
</plugin>

Now I have problem while indexing content: Method threw 'java.lang.NoClassDefFoundError' exception. Cannot evaluate org.elasticsearch.action.index.IndexRequest.toString()

So some other dependencies are missing or org.elasticsearch is not properly imported.

Is there a better way to do this? I've seen some with creating bundle with third party dependencies (using Eclipse to create plugin as standard OSGi package), but I am not sure how then to include that dependencies in main (core) bundle. Any other recommendation?

Note:

  <_fixupmessages>"Classes found in the wrong directory";is:=warning</_fixupmessages>

This was needed because when I add elasticsearch artifactid in Embed-package I can not run code because of this error:

Tried that, but many things can not get resolved that way in my case.

Hi @tadijam47062732 were you able to resolve it in the end? I am facing a similar issue while using elasticsearch in AEM. Can you please let me know?

@cqsapientu69896 you can see it here - I've manually created elasticsearch as separate OSGi bundles in Eclipse and reuse them in my project. You can check everything here: https://github.com/tadijam64/search-engines-comparison

Hi @tadijam47062732 thanks for replying we ended up using AWS lambda function but your reply might help someone else facing same issue

Can you run a clean of the Maven project? It could be old data from before making the changes have persisted
