no air speed history and fuel level history in air-traffic project

[hjhui]

hi,when I building the air-traffic example,some errors happened. After running the command "gradle clean tomcatRun", I can open this link: http://localhost:8090/airtraffic/, but there only has flight details without air speed and fuel level history.here are the logs:

Starting a Gradle Daemon, 2 busy Daemons could not be reused, use --status for details

> Task :air-traffic:tomcatRun
Gradle now uses separate output directories for each JVM language, but this build assumes a single directory for all classes from a source set. This behaviour has been deprecated and is scheduled to be removed in Gradle 5.0
