MRRC contains some redhat artifacts without sources. The interesting thing is that the MRRC zip file contains files such as
org/apache/tomcat/tomcat-el-api/8.0.36.redhat-30/tomcat-el-api-8.0.36.redhat-30-sources.jar.md5 org/apache/tomcat/tomcat-el-api/8.0.36.redhat-30/tomcat-el-api-8.0.36.redhat-30-sources.jar.sha1 org/apache/tomcat/tomcat-jsp-api/8.0.36.redhat-30/tomcat-jsp-api-8.0.36.redhat-30-sources.jar.md5 org/apache/tomcat/tomcat-jsp-api/8.0.36.redhat-30/tomcat-jsp-api-8.0.36.redhat-30-sources.jar.sha1 org/apache/tomcat/tomcat-servlet-api/8.0.36.redhat-30/tomcat-servlet-api-8.0.36.redhat-30-sources.jar.md5 org/apache/tomcat/tomcat-servlet-api/8.0.36.redhat-30/tomcat-servlet-api-8.0.36.redhat-30-sources.jar.sha1
but the appropriate source jar artifacts are missing.
