Thanks for looking at this Jiangjie, In order for feature warnings to display, you have to add scalaCompileOptions.additionalParameters = ["-feature"] below line 131 in build.gradle at the root of the project. I posted the verbose output from enabling the flag on the ticket: https://issues.apache.org/jira/browse/KAFKA-1054?focusedCommentId=14356280&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14356280. Bottom line is: I don't think we can fix these feature warnings until Kafka stops supporting scala 2.9. I get these build errors when trying to build a 2.9 jar with the language imports brought in: /Users/blake/src/kafka/core/src/main/scala/kafka/javaapi/Implicits.scala:19: object language is not a member of package scala import scala.language.implicitConversions * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
