------------------------------------

             Summary: jackson-databind dependency missing in the configuration document
                 Key: LOG4J2-1867
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1867
             Project: Log4j 2
          Issue Type: Documentation
          Components: Documentation
    Affects Versions: 2.8.1
            Reporter: James Jithin


Was following the link:

http://logging.apache.org/log4j/2.x/manual/configuration.html

to configure log4j2 with yaml.

The following links:
http://logging.apache.org/log4j/2.x/maven-artifacts.html
http://logging.apache.org/log4j/2.x/manual/configuration.html#YAML
 asks to import the following dependencies:

<dependencies>
  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.8.1</version>
  </dependency>
  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.8.1</version>
  </dependency>
</dependencies>
<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-yaml</artifactId>
    <version>2.8.6</version>
</dependency>

But not
		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-databind</artifactId>
		</dependency>

which is a requirement.

Enabling debug mode didn't point out about missing classes com.fasterxml.jackson.databind.ObjectMapper and com.fasterxml.jackson.databind.JsonNode which are mentioned in YamlConfigurationFactory. Such messages on missing classes is really going to help in resolving issues at the earliest. Please add the missing dependency to the YAML section. I see that it is provided for JSON configuration, but missed for YAML.
