Plugin classes must extend play.api.Plugin and are automatically discovered by searching for all play.plugins files in the classpath.
A play.plugins file contains a list of plugin classes to be loaded, and sorted by priority:
100:play.api.i18n.MessagesPlugin 200:play.api.db.DBPlugin 250:play.api.cache.BasicCachePlugin 300:play.db.ebean.EbeanPlugin 400:play.db.jpa.JPAPlugin 500:play.api.db.evolutions.EvolutionsPlugin 1000:play.api.libs.akka.AkkaPlugin 10000:play.api.GlobalPlugin

Scans the application classloader to retrieve a resource.
Scans the application classloader to retrieve a resource.
The conf directory is included on the classpath, so this may be used to look up resources, relative to the conf directory.
For example, to retrieve the conf/logger.xml configuration file:
val maybeConf = application.resource("logger.xml")
the absolute name of the resource (from the classpath root)
the resource URL, if found
Scans the application classloader to retrieve a resource’s contents as a stream.
Scans the application classloader to retrieve a resource’s contents as a stream.
The conf directory is included on the classpath, so this may be used to look up resources, relative to the conf directory.
For example, to retrieve the conf/logger.xml configuration file:
val maybeConf = application.resourceAsStream("logger.xml")
the absolute name of the resource (from the classpath root)
