[logback-user] Problems with groovy configuration and SizeAndTimeBasedFNATP

[Christian Brandel]

Hi all,

I was playing around with groovy based configuration to try and do some 
conditional configuration.
However I could not get size and time based archiving to work.
After much trial and error I simply took the example from the 
documentation 
(http://logback.qos.ch/manual/appenders.html#SizeAndTimeBasedFNATP), hit 
the "view as .groovy" button and got the following code which I tried:

import ch.qos.logback.classic.encoder.PatternLayoutEncoder
import ch.qos.logback.core.rolling.RollingFileAppender
import ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP
import ch.qos.logback.core.rolling.TimeBasedRollingPolicy

import static ch.qos.logback.classic.Level.DEBUG

appender("ROLLING", RollingFileAppender) {
  file = "mylog.txt"
  rollingPolicy(TimeBasedRollingPolicy) {
    fileNamePattern = "mylog-%d{yyyy-MM-dd}.%i.txt"
    timeBasedFileNamingAndTriggeringPolicy(SizeAndTimeBasedFNATP) {
      maxFileSize = "100MB"
    }
  }
  encoder(PatternLayoutEncoder) {
    pattern = "%msg%n"
  }
}
root(DEBUG, ["ROLLING"])


This gave me the following (lengthy) error message:

Failed to instantiate [ch.qos.logback.classic.LoggerContext]

Has anybody gotten SizeAndTimeBasedFNATP working with groovy?

Thanks for any hints,
