> Documentation is subzero quality as far as yaml config files are concerned
> --------------------------------------------------------------------------
>
> Key: LOG4J2-1379
> URL: https://issues.apache.org/jira/browse/LOG4J2-1379
> Project: Log4j 2
> Issue Type: Bug
> Reporter: piero de salvia
> Attachments: log4j2.xml, log4j2.yaml
>
>
> Documentation for yaml config files
> http://logging.apache.org/log4j/2.x/manual/configuration.html
> fails to mention that this dependency must be added to actually use yaml
> config files:
> {code}
> <dependency>
> <groupId>com.fasterxml.jackson.dataformat</groupId>
> <artifactId>jackson-dataformat-yaml</artifactId>
> <version>2.7.4</version>
> </dependency>
> {code}
> It also fails to mention that the equivalent basic config in yaml is the
> following:
> {code}
> Configuration:
> status: warn
> Appenders:
> Console:
> name: Console
> target: SYSTEM_OUT
> PatternLayout:
> Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
> Loggers:
> Root:
> level: info
> AppenderRef:
> ref: Console
> {code}
> At runtime, log4j2 "does not find" the config file (useless and misleading
> error message), which in reality means it does not find the needed
> dependencies.
> To actually fix this, one must debug log4j2.
> So basically failing to mention something in documentation (effort = 0)
> causes users to have to debug log4j (effort >> 0).
> This gives the whole project an amateurish and unkempt feel.
