Here is a minimal reproduction
{code:java}
# 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"
{code}
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.
