java - ClassNotFoundException with ResteasyClientBuilder (JBOSS) -

similar questions have been posted here , here former proposes solutions nosuchmethoderror , latter doesn't mention resteasyclientbuilder, precisely causes error whenever try call get method client.

i'm using wildfly, maven, resteasy/jboss. can run wildfly server using standalone in command prompt, , use maven deploy war file wildfly server, , use get methods in browser/postman receive results. if try call exact same get method within client code, error below. caused resteasyclientbuilder.

what wrong? have minimal dependencies , plugins in pom , server code works, client not. pom uses versions "3.0.19.final" because that's jar version resteasy-jaxrs-3.0.19.final.jar in c:\users\me\documents\wildfly\wildfly-10.1.0.final\modules\system\layers\base\org\jboss\resteasy\resteasy-jaxrs\main

edit configurations in intellij

the error remains after explicilty referencing client jar. wrong?

you need divided maven project on 2 parts. 1 client demo. war. in war's pom add dependency on org.jboss.resteasy:jaxrs-api , make provided. in client pom add dependency on org.jboss.resteasy:resteasy-client without provided (maven exec plugin don't include provided dependency in classpath) put reasteasy demo projects on github (server, client). test additional funciton , need more dependency in case. client can work through mvn exec:exec
