@@simplifyingtech I'm getting some error like this Caused by: java.lang.UnsupportedClassVersionError: org/elasticsearch/index/query/QueryBuilder has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0 (unable to load class [org.elasticsearch.index.query.QueryBuilder])
DO you know what might be the reason?

[@simplifyingtech]

@@sharonshelton1575 hmm good qus , so you are using Java 17 version (class file version 61.0), use JDK 8 (Java Runtime only recognizes class file versions up to 52.0 )to proceed further. this will solve your problem.

[@sharonshelton1575]

@@simplifyingtech I'm using JDK version 8. Dont know why this is happening. Were you using, jdk 8 as well?

[@simplifyingtech]

Hmm tutorial is used jdk 8 only. check your eclipse or ide project using which version not use default version.. check in you java build path project..
