[jira] Commented: (BVAL-84) CNFEX org.slf4j.impl.StaticLoggerBinder building xstream and guice

["Carlos Vara (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BVAL-84?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12924779#action_12924779 ] 

Carlos Vara commented on BVAL-84:
---------------------------------

Tried to reproduce but couldn't. Linux and sun's JDK here.

During mvn install, SLF4J defaults to no logging correctly:
Running org.apache.bval.guice.GuiceAwareValidationTestCase
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

If your problem is when consuming the built jars, you will need to declare the dependency for your chosen backend in your project (slf4j-log4j, slf4j-simple, etc.). We should not declare that dependency in our pom, as it's the consumer's decision what backend suits them best.
