试着寻找各种线索，但不知怎么还是搞不清楚。
我有一个基于maven的java应用程序，它生成一个jar文件。下面是我的pom.xml

            <version>1.2.15</version>
        </dependency>           
    </dependencies>
</project>

我的log4j.properties放在src/main/resources下，内容如下：

# Root logger option

log4j.rootLogger=DEBUG, file

# Redirect log messages to a log file, support file rolling.

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/tmp/jdbc-formatter.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

以下是我的主要课堂内容：

private static final Logger log = LogManager.getLogger(FormatterEntryPoint.class);

public static void main(String[] args) {
    BasicConfigurator.configure();
    CommandLineArgumentsHandler cliHandler = new CommandLineArgumentsHandler();
    try {
        cliHandler.parse(args);
    } catch (IllegalArgumentException e) {
        log.debug(e.getMessage(),e);
        System.err.println("Usage: java -jar <program_name> -input=<path_to_jdbc_log> -output=<output_file>");
    }    
}

当我从命令行运行jar时，虽然我在控制台中看到日志消息，但是日志文件/tmp/jdbc-formatter.log没有被创建。有什么意见吗？
谢谢。
