Hello,

I used to enable debug logging in my Maven project's unit tests by just setting log4j's global level to DEBUG, very handy, especially in debugging some Solr Cloud start up issues. Since a while, not sure to long, i don't seem to be able to get any logging at all. This project depends on 6.3. Anyone here that can tell me how to get something so simple but so helpful back to work?

Many thanks,
Markus

$ cat src/test/resources/log4j.properties
log4j.rootLogger=debug,info,stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

Seems like you have enabled only console appender. I remember there was a
changed made to disable console appender if Solr is started in background
mode.

Indeed, there were some changes recently but i also can't get logging to work on older versions such as 6.0.

Thanks,
Markus

Ahá, i am stupid indeed. I forgot i also had to change slf4j-nop to slf4j-simple in my pom.xml..

    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-simple</artifactId>
      <version>1.7.21</version>
      <scope>test</scope>
    </dependency>

Sorry for the noise!
