Configuring log4j for use in a groovy script. Reading log4j config (via a config slurper)

log4jconfig.groovy

log4j {

    appender.stdout = "org.apache.log4j.ConsoleAppender"
    appender."stdout.layout"="org.apache.log4j.PatternLayout"
    appender.scrlog = "org.apache.log4j.FileAppender"
    appender."scrlog.layout"="org.apache.log4j.TTCCLayout"
    appender."scrlog.file"="script.log"

    rootLogger="debug,scrlog,stdout"

    /** these don't do nothing but illustrate how to configure logging on packages
    logger.org.springframework="info,stdout"
    additivity.org.springframework=false
    **/
}
