[xml] Very simple log4j2 XML configuration file using Console and File appender

Here is my simplistic log4j2.xml that prints to console and writes to a daily rolling file:

// java
private static final Logger LOGGER = LogManager.getLogger(MyClass.class);


// log4j2.xml
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Properties>
        <Property name="logPath">target/cucumber-logs</Property>

    </Properties>
    <Appenders>
        <Console name="console" target="SYSTEM_OUT">
            <PatternLayout pattern="[%highlight{%-5level}] %d{DEFAULT} %c{1}.%M() - %msg%n%throwable{short.lineNumber}" />
        </Console>
        <RollingFile name="rollingFile" fileName="${logPath}/${rollingFileName}.log" filePattern="${logPath}/${rollingFileName}_%d{yyyy-MM-dd}.log">

            <Policies>
                <!-- Causes a rollover if the log file is older than the current JVM's start time -->
                <OnStartupTriggeringPolicy />
                <!-- Causes a rollover once the date/time pattern no longer applies to the active file -->
                <TimeBasedTriggeringPolicy interval="1" modulate="true" />
            </Policies>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="DEBUG" additivity="false">
            <AppenderRef ref="console" />
            <AppenderRef ref="rollingFile" />
        </Root>
    </Loggers>
</Configuration>

TimeBasedTriggeringPolicy

interval (integer) - How often a rollover should occur based on the most specific time unit in the date pattern. For example, with a date pattern with hours as the most specific item and and increment of 4 rollovers would occur every 4 hours. The default value is 1.

modulate (boolean) - Indicates whether the interval should be adjusted to cause the next rollover to occur on the interval boundary. For example, if the item is hours, the current hour is 3 am and the interval is 4 then the first rollover will occur at 4 am and then next ones will occur at 8 am, noon, 4pm, etc.

A new log file will be created daily with previous day automatically renamed to:

cucumber_yyyy-MM-dd.log

In a Maven project, you would put the log4j2.xml in src/main/resources or src/test/resources.
