Apache Camel not printing FTP logs

Question

I have a route in Apache Camel that I am calling from a Spring Boot application. My Camel route picks up a file from one server using FTP and transfers to another server using FTP. My route looks like the below:

public void configure() throws Exception {
        errorHandler(defaultErrorHandler()
                .maximumRedeliveries(3)
                .redeliveryDelay(1000)
                .loggingLevel(LoggingLevel.DEBUG)
                .retryAttemptedLogLevel(LoggingLevel.DEBUG));

        from("direct:transferFile")
            .doTry()
                .log("Transferring file")
                .process(requestProcessor)
                .log("${exchangeProperty.inputEndpoint}")
                .pollEnrich()
                    .simple("${exchangeProperty.inputEndpoint}").timeout(0).aggregationStrategy(requestAggregator)
                .choice()
                    .when(body().isNotNull())
                        .toD("${exchangeProperty.outputEndpoint}", true)
                        .log("File transferred")
                        .endChoice()
                    .otherwise()
                        .log("Empty body, exiting")
                        .endChoice()
                .endDoTry()
            .doCatch(Exception.class)
                .log("Exception")
            .end();
    }

The problem is it is not printing the FTP logs like username, password etc when it is attempting to connect to the FTP servers. Can anyone please let me know how can I enable the FTP logs?

Just enable TRACE level for "org.apache.camel.component.file.remote" package. Here log4j2 example:

appender.stdout.type = Console
appender.stdout.name = stdout
appender.stdout.layout.type = PatternLayout
appender.stdout.layout.pattern = %d [%-15.15t] %-5p %-30.30c{1} - %m%n
rootLogger.level = INFO
rootLogger.appenderRef.stdout.ref = stdout

logger.stdout.name = org.apache.camel.component.file.remote
logger.stdout.level = TRACE

Output:
