logstash-logback-encoder not works when deploys Tomcat

Question

I'm having problems using the logstash-logback-encoder. I'm using the encoder:

<appender name="FILE-ERROR" class="ch.qos.logback.core.FileAppender">
    <file>${LOG_FILE_PATH}${ERROR_FILE_NAME}</file>
    <append>true</append>
    <immediateFlush>true</immediateFlush>
    <!-- Filtro de level -->
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
        <level>ERROR</level>
    </filter>
    **<encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">**
        ...

My pom.xml is:

    <dependency>
        <groupId>net.logstash.logback</groupId>
        <artifactId>logstash-logback-encoder</artifactId>
        <version>6.4</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-core</artifactId>
        <version>1.2.3</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.2.3</version>
    </dependency>

It works fine when I'm running through intellij, but when I deploy to Tomcat I have this error:

    10-Jul-2020 18:47:34.906 INFO [localhost-startStop-2] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs.

Has anyone ever experienced this?

Answer 1

It looks like this is the root cause...

ERROR in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Could not create component [encoder] of type [net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder] java.lang.ClassNotFoundException: net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder

Double check that the logstash-logback-encoder jar is in the war that you are deploying to tomcat.
