Hi, I also checked you 0.14 release and noticed that it contained compiled code (gradle.jar file). I'm not on your PMC, but I suggest you reviews this as compiled code is generally not allowed in the source release. There are a number of ways around this issue, the simplest being to not include it in the release artificial but leave it in version control or create a convenience binary operate to the source release that consists of source release and gradle wrapper.
Kind Regards, Justin
