Subject: [logback-dev] multiple appender-refs in <root> : unexpected
	behaviour ?
References: <734465709.1182501.1745403576152.ref@mail.yahoo.com>
Message-ID: <mailman.11853.1745403579.386910.logback-dev@qos.ch>

Using logback-classic in Maven:
    <dependency>       <groupId>ch.qos.logback</groupId>      <artifactId>logback-classic</artifactId>      <version>1.5.18</version>      <scope>runtime</scope>     </dependency> 
If one <root> appender-ref is defined (STDOUT) but another is undefined (CLOUD_LOGGING):
  <root level="info">     <appender-ref ref="STDOUT" />    <appender-ref ref="CLOUD_LOGGING" />     </root>
logback fails to  set the defined appender in <root>.
In main() after server.start()I see WARN in Logger[org.eclipse.jetty.server.Server] - No appenders present in context [default] for logger [org.eclipse.jetty.server.Server].
Is this expected behaviour ? Would be better if it selected whichever is defined.
