I was getting a similar error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hc/core5/http2/HttpVersionPolicy at org.apache.hc.client5.http.config.TlsConfig$Builder.build(TlsConfig.java:211) at org.apache.hc.client5.http.config.TlsConfig.(TlsConfig.java:47) at

The solution was to add this library to the project.

httpcore5-h2-5.3.1.jar [https://mvnrepository.com/artifact/org.apache.httpcomponents.core5/httpcore5-h2/5.3.1][1]
