[wildfly-dev] org.apache.httpcomponents.core requires org.apache.commons.codec

Hi all, the Elasticsearch integration feature we have in Hibernate Search uses the Apache httpcomponents module from WildFly. In WildFly 14 we get: Exception in thread "Hibernate Search: Elasticsearch transport thread-2" java.lang.NoClassDefFoundError: org/apache/commons/codec/binary/Base64 2018-09-03 11:58:13,120 ERROR [stderr] (Hibernate Search: Elasticsearch transport thread-2) at org.apache.http.impl.auth.BasicScheme.authenticate(BasicScheme.java:168) 2018-09-03 11:58:13,120 ERROR [stderr] (Hibernate Search: Elasticsearch transport thread-2) at org.apache.http.impl.auth.HttpAuthenticator.doAuth(HttpAuthenticator.java:239) 2018-09-03 11:58:13,120 ERROR [stderr] (Hibernate Search: Elasticsearch transport thread-2) at org.apache.http.impl.auth.HttpAuthenticator.generateAuthResponse(HttpAuthenticator.java:218) 2018-09-03 11:58:13,120 ERROR [stderr] (Hibernate Search: Elasticsearch transport thread-2) at org.apache.http.impl.nio.client.MainClientExec.generateRequest(MainClientExec.java:224) Seems that the `org.apache.httpcomponents.core` is not declaring the dependency on module `org.apache.commons.codec`. One complexity is that the first one is included in WildFly core, the second is only added by WildFly full. I guess I could add an optional dependency, but I wonder if many more users would expect the basic authentication scheme to work in WildFly core? In that case you would probably prefer to include the codec in WildFly Core. I can try fixing this but would need to know which solution you all prefer. Also, not sure about the severity: definitely bad for Hibernate Search users, but I don't know which other components might be using this module.
