SLF4J, logback and groovy

logback.groovy does not support

<configuration debug="true"> in logback.xml.

statusListener(OnConsoleStatusListener) may help.

Or add the below to the source:

LoggerContext lc = (LoggerContext)LoggerFactory.getILoggerFactory();

StatusPrinter.print(lc);

HelloWorld.java

package log;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import ch.qos.logback.classic.LoggerContext;

import ch.qos.logback.core.util.StatusPrinter;

public class HelloWorld {

public static void main(String[] args) {

LoggerContext lc = (LoggerContext)LoggerFactory.getILoggerFactory();

StatusPrinter.print(lc);

Logger logger = LoggerFactory.getLogger(HelloWorld.class);

logger.info("Hello World!");

}

}

logback.xml

<configuration debug="true">

  <appender name="FILE" class="ch.qos.logback.core.FileAppender">

    <file>myApp.log</file>

    <encoder>

      <pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</pattern>
