If condition in logback - print log messages in two different folders

Question

I am writing code for log messages in two different folders with the same log level. The problem I am facing is that the code below cannot print log messages by condition (when it becomes different). at work.

Simply put, how to write logs to two different folders based on an If else condition using two different applications.

the code:

<if condition='property("type").contains("DEV")'>
    <then>
        <appender-ref ref="FILE-ENGINE" />
    </then>
    <else>
        <appnder-ref ref = "FILE-UI" />
    </else>
</if>

Entire configuration file:

<configuration>

    <property name="USER_HOME" value="D:/Log1/" />

    <property name="USER_HOME2" value="D:/log2/" />


    <if condition='property("type").contains("DEV")'>
        <then>
            <appender-ref ref="FILE-ENGINE" />
        </then>
        <else>
            <appnder-ref ref = "FILE-UI" />
        </else>
    </if>


    <appender name="FILE-ENGINE" class="ch.qos.logback.core.FileAppender">
        <file>${USER_HOME}/${log.name}.log</file>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{35} -
                %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="FILE-UI" class="ch.qos.logback.core.FileAppender">
        <file>${USER_HOME2}/DEBUG.log</file>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{35} -
                %msg%n</pattern>
        </encoder>
    </appender>


    <appender name="FILE-ENGINE-ERROR" class="ch.qos.logback.core.FileAppender">
        <file>${USER_HOME}/${log.name}.error</file>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} -
                %msg%n</pattern>
        </encoder>
    </appender>


    <logger name="com.code" level="debug" additivity="false">
        <appender-ref ref="FILE-ENGINE" />
        <appender-ref ref="FILE-UI" />

    </logger>

    <root level="Error">
        <appender-ref ref="FILE-ENGINE-ERROR" />
    </root>

</configuration>

Please help me how to write journals with the else clause. Thanks in advance.

2. if. appenders.

    <if condition='property("type").contains("DEV")'>
    <then>
        <appender name="fileAppender1" class="ch.qos.logback.core.FileAppender">
        <file>${USER_HOME}/${log.name}.log</file>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{35} -
                %msg%n</pattern>
            </encoder>
        </appender>
    </then>
    <else>
        <appender name="fileAppender1" class="ch.qos.logback.core.FileAppender">
        <file>${USER_HOME2}/${log.name}.log</file>
        <append>true</append>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{35} -

            </encoder>
        </appender>
    </else>
    </if>

    <root level="DEBUG">
        <appender-ref ref="fileAppender1" />
