How to stop logback status INFO at the start of every log?

The logbook will output its own status (INFO or WARN) at the start of the program, it’s really annoying!


15:34:46,181 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy]
15:34:46,181 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml]

15:34:46,267 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [STDOUT]
15:34:46,319 |-WARN in ch.qos.logback.core.ConsoleAppender[STDOUT] - This appender no longer admits a layout as a sub-component, set an encoder instead.
15:34:46,319 |-WARN in ch.qos.logback.core.ConsoleAppender[STDOUT] - To ensure compatibility, wrapping your layout in LayoutWrappingEncoder.
15:34:46,319 |-WARN in ch.qos.logback.core.ConsoleAppender[STDOUT] - See also http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for details

15:34:46,322 |-INFO in ch.qos.logback.classic.joran.JoranConfigurator@7bb11784 - Registering current configuration as safe fallback point

Solution

To fix it, add a NopStatusListener like this :

logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <!-- Stop output INFO at start -->
    <statusListener class="ch.qos.logback.core.status.NopStatusListener" />

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} %-5level %logger{36} - %msg%n
            </Pattern>
        </layout>
    </appender>

    <root level="error">
        <appender-ref ref="STDOUT"/>
    </root>

</configuration>
