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 = "[email protected]"
from = " [email protected] "
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]
Reported exception:

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.

Rathnadhar.K.V
