ERROR "JBAS015010: The deployment scanner found a directory named META-INF / WEB-INF that was not inside a directory whose name ends with .ear, .jar, .rar, .sar or .war." in JBoss EAP 6

Issue

The following ERROR message was shown in the server.log in JBoss EAP 6:

ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) JBAS015010: The deployment scanner found a directory named META-INF that was not inside a directory whose name ends with .ear, .jar, .rar, .sar or .war. This is likely the result of unzipping an archive directly inside the /path/to/jboss-eap-6.x/standalone/deployments directory, which is a user error. The META-INF directory will not be scanned for deployments, but it is possible that the scanner may find other files from the unzipped archive and attempt to deploy them, leading to errors.
