My logback configuration is:

<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
        </Console>
        <RollingFile name="RollingFile" fileName="${sys:home}/logs/log"
            filePattern="${sys:home}/logs/mylog-%i.log" bufferedIO="false"
            immediateFlush="true" append="true">
            <PatternLayout>
                <pattern>%d %p [%t] %c{1.} %m%n</pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="20 MB" />
            </Policies>
            <DefaultRolloverStrategy max="100" />
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="error">
            <AppenderRef ref="RollingFile" />
            <AppenderRef ref="Console" />
        </Root>
        <Logger name="org.springframework" level="info" additivity="false">
            <AppenderRef ref="RollingFile"></AppenderRef>
            <AppenderRef ref="Console"></AppenderRef>
        </Logger>
        <Logger name="com.myproj" level="debug" additivity="false">
            <AppenderRef ref="RollingFile"></AppenderRef>
        </Logger>
    </Loggers>
</Configuration>
                I'm not 100% sure but it looks like you have incorrect syntax of logback configuration. Refer to logback.qos.ch/manual/configuration.html

This is probably log4j2 configuration. And to support it your Spring Boot pom file must be updated as following:
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
See more details here: https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto-logging (section 8.2 Configure Log4j for Logging).
                Had the same problem dealing with logback. For me, adding the implementation dependency for the current version worked without setting an exclusion.

                I think I just tried mp31415's solution (of just separately declaring spring-boot-starter-log4j2) and realised that I actually don't need the exclusion for it to work.

The error can be resolved by using
<appender name="Console"
            class="ch.qos.logback.core.ConsoleAppender">
instead of
<Console name="Console" target="SYSTEM_OUT">
Link for reference
Below is the reference how you can do it :-
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan = "true">
        <property name="LOGS" value="./logs" />
        <property resource ="application.yml"/>

        <appender name="Console"
            class="ch.qos.logback.core.ConsoleAppender">
            <layout class="ch.qos.logback.classic.PatternLayout">
                <Pattern>
                    %black(%d{ISO8601}) %highlight(%-5level) [%blue(%t)] %yellow(%C{1.}): %msg%n%throwable
                </Pattern>
            </layout>
        </appender>
        <appender name="RollingFile"
        class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOGS}/${NAME}.log</file>
        <encoder
            class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>%d %p %C{1.} [%t] %m%n</Pattern>
        </encoder>
        <rollingPolicy
            class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- rollover daily and when the file reaches 10 MegaBytes -->
            <fileNamePattern>${LOGS}/archived/spring-boot-logger-%d{yyyy-MM-dd}.%i.log
            </fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy
                class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
    </appender>
    <root level="info">
        <appender-ref ref="RollingFile" />
        <appender-ref ref="Console" />
    </root>
    <logger name="com.ms" level="trace" additivity="false">
        <appender-ref ref="RollingFile" />
        <appender-ref ref="Console" />
    </logger>
    <logger name="org.springframework.core.env.PropertySourcesPropertyResolver" level="trace" additivity="true">
    </logger>
</configuration>
