If i use elasticsearch-rest-high-level-client version 7.5.1, i got the following error:

> NoClassDefFoundError: org/elasticsearch/client/Cancellable

However, if i use lower version to 7.4.x, it works fine.  
I followed the guide and tried it on several computers.  
i use gradle.  
Is this just me?
