Logging

We recommand to patch your maven by using the procedure below for a better logging with our runners :

Note

In all the procedure $MVN_HOME is your maven installation directory, and $MVN_VERSION your maven version.

• Add in $MVN_HOME/lib/ext/ the jars :
  • log4j-slf4j-impl-2.5.jar
  • log4j-core2.5.jar
  • log4j-api-2.5.jar

• Create a logging configuration file called log4j2.xml in $MVN_HOME/conf/logging/ and fill it with :

<?xml version="1.0" encoding="UTF-8" ?>
<Configuration>
  <Properties>
    <Property name="maven.logging.root.level">INFO</Property>
  </Properties>
  <Appenders>
    <Console name="console" target="SYSTEM_OUT">
      <PatternLayout pattern="[%p] %msg%n%throwable" />
    </Console>
  </Appenders>
  <Loggers>
    <Root level="${sys:maven.logging.root.level}">
      <Appender-ref ref="console"/>
    </Root>
<!-- <logger name="[USER_MESSAGE]" level="DEBUG"/> -->
  </Loggers>
</Configuration>

• Remove if exists :
  • In the directory $MVN_HOME/lib the file maven-sl4j-provider-$MVN_VERSION.jar
  • In the directory $MVN_HOME/conf/logging/ the file deletesimpleLogger.properties
