Jar Class Conflict Error of twilio-java-sdk-3.3.15-jar-with-dependencies and http-client-4.4.1,http-client-4.4.1

my two jars are conflicting and showing me the error for SolrHttpServer Instantiation for Solr-4.7.2.



java.lang.NoSuchMethodError: org.apache.http.impl.conn.SchemeRegistryFactory.createSystemDefault()Lorg/apache/http/conn/scheme/SchemeRegistry;



I checked and found that "http-client-4.4.1.jar", "http-core-4.4.1.jar" with a messaging API "twilio-java-sdk-3.3.15-jar-with-dependencies.jar"



Also, I have commons-httpclient-3.1.jar in my classpath.



The SchemeRegistryFactory class is present in these two jars. and also I have tried the http jars with other versions too.



any way to remove this conflict. ??



Tried Searching on Internet but didn't got success.
