Log4j 2 console output stop working - log4j2

Question

I've been using log4j 2 (2.7) and it worked very well until I had to reinstall the IDE (Eclipse Neon J2EE edition).
Now I only works loggingto a log file but not to the console.
This is my log4j2.xml file:
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
</Console>
<File name="log" fileName="target/test.log" append="true">
<PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %class{36} %L %M %msg%xEx%n"/>
</File>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="Console"/>
</Root>
<Root level="TRACE">
<AppenderRef ref="log" />
</Root>
</Loggers>
The output to the log works perfectly, as I said.

Answer 1

Try declaring Root only once.
Example:
<Loggers>
<Root>
<AppenderRef ref="Console" level="error"/>
<AppenderRef ref="log" level="trace"/>
</Root>
</Loggers>

Answer 2

I agree with Sazzad 's answer: you can only have one root logger. I would suggest specifying a level on the root logger and override the level only on the AppenderRef that need it. So:
<Loggers>
<Root level="trace">
<AppenderRef ref="Console" level="error"/>
<AppenderRef ref="log"/>
</Root>
</Loggers>
Also, not sure if this was omitted just from the question or from the actual configuration file, but the configuration really should start with a <Configuration> and end with a </Configuration> element.
