I get the following error :

Maven provides a logging configuration. It sounds more like
log4j.properties is specified somewhere (JAVA_OPTS or MAVEN_OPTS?) and
is not valid.

Maven uses commons-logging from the jakarta project. You can set up
log4j to accept the logs. Create a log4j.properties file on the
classpath. It could look like this:
log4j.rootLogger = info, default
log4j.appender.default = org.apache.log4j.ConsoleAppender
log4j.appender.default.layout = org.apache.log4j.TTCCLayout
log4j.appender.default.layout.DateFormat = ABSOLUTE
This will output log messages of info level and above to the console.
If you want to learn more about log4j settings, take a look at:
http://logging.apache.org/log4j/docs/
HTH,
Maury
