Transitive Dependency: Using Elasticsearch Rest High Client problem in AEM

Question

I am trying to use Java High Level Rest Client in Adobe Experience Manager to finish project of comparison between Lucene, Solr and Elasticsearch search

Answer 1

So my guess was right, transitive dependencies were not included altho true exists.

The following is necessary when running elasticsearch as a search engine on AEM the problem:

• I have added all transitive dependencies in pom.xml (versions are defined in parent/pom.xml):

    
        
            org.elasticsearch.client
            elasticsearch-rest-high-level-client
        
        
            org.elasticsearch.client
            elasticsearch-rest-client
        
        
            org.elasticsearch
            elasticsearch
        
        
            org.elasticsearch
            elasticsearch-x-content
        
        
            org.elasticsearch.plugin
            rank-eval-client
        
        
            org.apache.commons
            commons-imaging
            test
        
        
            org.elasticsearch.plugin
            lang-mustache-client
        
        
            org.apache.httpcomponents
            httpasyncclient
        
  

It is important to add all third-party dependencies as <Embed-Dependency> inside maven-bundle-plugin like this:

    
        org.apache.felix
        maven-bundle-plugin
        true
        
            
                org.apache.servicemix.bundles.solr-solrj, noggit,
                    elasticsearch-rest-high-level-client,
                    elasticsearch,
                    elasticsearch-rest-client,
                    elasticsearch-x-content,
                    elasticsearch-core,
                    rank-eval-client,
                    lang-mustache-client,
                    httpasyncclient;
                
                true
                OSGI-INF/lib
                we.retail.core.model*
                
                    *;resolution:=optional
                
                
                    we.retail.core*
                
                
                    we.retail.core.model
                
                <_fixupmessages>"Classes found in the wrong directory";is:=warning
            
        
    

Important to notice:

• All third-party dependencies (the ones outside of OSGi) must be included in the "Embed-Dependency"
• "Embed-Transitive" must be set to true to include transitive dependencies
• "Import-Package" must include "*;resolution:=optional" to exclude all dependencies that could not be resolved so that the program can run normally
• For some reason, there was an error in compile time when "elasticsearch" dependency was added which is not important for this task, so I've decided to ignore it this way:

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

Though challenging, I finally resolved it. There are many similar or the same problems on Google, so I hope this will help someone. Thanks to everyone that tried to help.
