How can I change logger pattern?

Question

Does any one know how to change the log pattern in log console in the Scala code? I want to change the pattern to "%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n".

I have the below code but it does not work

val rootLogger: Logger = Logger.getRootLogger
val pattern = "yyyy-MM-dd HH:mm:ss %-5p %c{1}:%L - %m%n"
rootLogger.removeAllAppenders()
rootLogger.addAppender(new ConsoleAppender(new PatternLayout(pattern)))
rootLogger.setLevel(Level.ERROR)
