Description

Using the gfsh (Geode 1.6.0) command to deploy a JAR containing the Scala library results in the following error:

Here is a minimal reproduction

 # download Scala 2.11.12
 curl -O [http://central.maven.org/maven2/org/scala-lang/scala-library/2.11.12/scala-library-2.11.12.jar]

 # or Scala 2.12.6
 curl -O [http://central.maven.org/maven2/org/scala-lang/scala-library/2.11.12/scala-library-2.11.12.jar]

gfsh \
 -e "start locator --name=locator1" \
 -e "start server --name=server1" \
 -e "deploy --jar=scala-library-2.12.6.jar"

This appears to be a [known issue|https://github.com/lukehutch/fast-classpath-scanner/issues/193] with fast-classpath-scanner and has been fixed in >= 2.19.0. Changing `fast-classpath-scanner.version` to `2.19.0` allows the Scala library JAR to be deployed.
