Hey guys,

Iam trying to develop a native elasticsearch service for my project. Im using Java API and followed all guide but i got these exception below:

org.elasticsearch.common.collect.ComputationException: java.lang.NoClassDefFoundError: org/apache/lucene/analysis/ga/IrishAnalyzer

I searched any-all Google results and much of them say that this issue is related with Maven dependency besides it is not meaningful to me. Here is my usage:

Node node = NodeBuilder.nodeBuilder().node();  
Client \_nodeClient = node.client();  
SearchResponse resSearch = null;  
try{  
resSearch = \_nodeClient.prepareSearch("videos")  
.setSearchType(SearchType.DEFAULT)  
.setQuery(QueryBuilders.queryString("q:anytext"))  
.setFrom(0).setSize(60).setExplain(true)  
.execute()  
.actionGet();

I removed all inner codes and left only

Node node = NodeBuilder.nodeBuilder().client(true).node();

But still getting this error org.elasticsearch.common.collect.ComputationException: java.lang.NoClassDefFoundError: org/apache/lucene/analysis/ga/IrishAnalyzer

I searched and can not find any response. I could not figured it out why this error coming up ☹

Need help.
