Description

add the capability to exchange the defauly log4j logging implementation with a different framework (e.g. logback). Ideally the mechanism to do so would be identical to Grails as outlined in this article: http://www.lazygun.net/grails-replacing-log4j-with-logback

See the griffon user mailing list discussion: How does one replace log4j with logback

Instructions as explained on that blog post do work for Griffon too.

1. Exclude log4j dependencies from global space, but do not exclude log4j-1.2.16 as it will cause a CNFE at runtime (some classes are required by the logging DSL).

2. configure Logback in the dependency DSL, like this

griffon.project.dependency.resolution = {
    inherits("global") {
        excludes 'slf4j-log4j12', 'log4j-over-slf4j'
    }
    log "warn"
    repositories {
        griffonHome()
        mavenCentral()
    }
    dependencies {
        String logbackVersion = '1.0.0'
        build   "ch.qos.logback:logback-core:$logbackVersion",
                "ch.qos.logback:logback-classic:$logbackVersion"
        runtime "ch.qos.logback:logback-core:$logbackVersion",
                "ch.qos.logback:logback-classic:$logbackVersion"
    }
}

3. Create a suitable Logback configuration in griffon-app/conf/resources/logback.xml

<configuration debug="true" scan="true" scanPeriod="30 seconds">
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <layout>
      <pattern>%d{HH:mm:ss.SSS} %-5level %logger{36} - %msg%n</pattern>
    </layout>
  </appender>

  <logger name="griffon" level="INFO"/>
  <logger name="org.codehaus.griffon" level="DEBUG"/>

  <root level="warn">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>

4. Profit!

Disabling all Log4j dependencies and enabling a Logback DSL would be different RFEs.

I found that for Griffon, putting a logback.groovy DSL config file in griffon-app/resources works.
I haven't tried it for Grails yet, YMMV.
