files in directories (as opposed to explicitly on the classpath). In the case of the
`[Jar|War]Launcher` the nested paths are fixed (`+lib/*.jar+` and `+lib-provided/*.jar+` for
the war case) so you just add extra jars in those locations if you want more. The
`PropertiesLauncher` looks in `lib/` by default, but you can add additional locations by
`PropertiesLauncher` looks in `lib/` in your application archive by default, but you can add additional locations by
setting an environment variable `LOADER_PATH` or `loader.path` in `application.properties`
(comma-separated list of directories or archives).
