[logback-user] Logback.groovy configuration results in java.lang.VerifyError exception.

28 Feb 2011

      Namasthe,

I have switched from log4j to logback. For configuration,  I initially
worked with logback.xml  which worked fine. I wanted to get rid of xml
so re-wrote the logback.xml in groovy. 

The logback.groovy is as below:

import ch.qos.logback.classic.PatternLayout

import ch.qos.logback.classic.filter.ThresholdFilter

import ch.qos.logback.classic.net.SMTPAppender

import ch.qos.logback.core.ConsoleAppender

import ch.qos.logback.core.rolling.FixedWindowRollingPolicy

import ch.qos.logback.core.rolling.RollingFileAppender

import ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy

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

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

appender("RootFileAppender", RollingFileAppender) {

  file = "project"

  append = true

  filter(ThresholdFilter) {

    level = INFO

  }

  rollingPolicy(FixedWindowRollingPolicy) {

    fileNamePattern = "project_log.%i"

    maxIndex = 1

  }

  triggeringPolicy(SizeBasedTriggeringPolicy) {

    maxFileSize = 1000000

  }

  layout(PatternLayout) {

    pattern = "%d{yyyy-MM-dd HH:mm:ss}, %p, %c, %t, %ex, %F, %L, %C{1},
%M %m%n"

  }

}

appender("RootConsoleAppender", ConsoleAppender) {

  filter(ThresholdFilter) {

    level = INFO

  }

  layout(PatternLayout) {

    pattern = "%d{yyyy-MM-dd HH:mm:ss}, %p, %c, %t %m%n"

  }

}

appender("RootEmailAppender", SMTPAppender) {

  filter(ThresholdFilter) {

    level = ERROR

  }

  bufferSize = 10

  SMTPHost = "smtp.hostaddress"

  to = "logback.user@xyz.com"

  from = " logback.user@xyz.com "

  username = "user"

  password = "password"

  subject = "Logback Error"

  layout(PatternLayout) {

    pattern = "%d{yyyy-MM-dd HH:mm:ss}, %p, %c, %t, %ex, %F, %L, %C{1},
%M %m%n"

  }

}

root(INFO, ["RootFileAppender", "RootConsoleAppender",
"RootEmailAppender"])

 (Some values have been masked for security reasons).

I put this file in the classpath. 

After that I started my application, but I got this exception:

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

When I switch from logback.groovy to logback.xml, everything works
perfectly (both the configurations are equal in functionality).

My google search did not yield useful information. 

I am using the following jars:

1.       groovy-all-1.7.8.jar

2.       logback-access-0.9.28.jar

3.       logback-classic-0.9.28.jar

4.       logback-core-0.9.28.jar

5.       slf4j-api-1.6.1.jar

Can somebody please help me to resolve the issue.

Regards
