As soon as I run a scala program using sbt with **elas4s** dependencies ,it throws an error  
**Plugin [reindex] is incompatible with Elasticsearch [2.3.0]. Was designed for version [2.3.5]**  
even though i am using elasticsearch version 2.3.5.

This sounds like a version mismatch in elas4s or your dependencies somewhere. Make sure version of the reindex jar matches the Elasticsearch jar.

These tests are fairly paranoid but they are there to prevent sneaky bugs we've seen in the past. Sorry for the inconvenience!

Thanks! But I still dont get it. The version of **elasticsearch** which i am using is **2.3.5** and is compatible with **elas4s** versions **2.3.0** and I have added dependencies in my build.sbt file accordingly.

I suspect elas4s is depending on elasticsearch 2.3.0. So you'd use reindex 2.3.0. That should work fine communicating with a 2.3.5 server.
