No way to avoid SLF4J error in maven - maven

Question

I know this has been asked before but none of the answers has worked for me yet. I get the error:
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.
I've allready tryed to use:
Only slf4j-api
slf4j-api and log4j
slf4j-api, jcl-over-slf4j, log4j
Only slf4j-log4j12
slf4j-log4j12 and log4j
Only logback-classic
logback-classic and logback-core
slf4j-api, logback-classic and logback-core
log4j-api 2, log4j-core 2, log4j-slf4j-impl
log4j-over-slf4j, jul-to-slf4j, logback-classic
slf4j-api, logback-classic
For each one I've tried with the tutorial/answer version and the latest (mvn versions:use-latest-version)
Since there are some answers arround there that tells you can only have one of those libraries on your classpath I remark that I've already tryed em.
Also I've used a log4j.properties inside src/main/resources/ like this one:
# Set root logger level and appender name.
log4j.rootLogger = ALL, file
# Specify appenders.
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.file = org.apache.log4j.DailyRollingFileAppender
# Configure console appender.
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern = %d{ABSOLUTE} [%t] %-5p %m%n
# Configure file appender.
log4j.appender.file.File = /webapp/logs/web.log
log4j.appender.file.DatePattern = '.'yyyy-MM-dd
log4j.appender.file.layout = org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern = %d{ABSOLUTE} [%t] %-5p %m%n
And a logback.xml at the same place:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>silkroad.log</file>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<logger name="com.base22" level="ALL"/>
<root level="debug">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>
This is the code I've tried out:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Test {
static Logger log = LoggerFactory.getLogger(Test.class);
public static void main(String[] args) {
log.debug("Testing the log");
}
}
Appart from the loggin dependences I use:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>1.1.2</version>
</dependency>
I've followed several tutorials (12~15) using different ways of geting the log facade working, including the ones on theyr sites without success.

Answer 1

This configuration works for a project I have. I am using log4j 1, a standard log4j.xml file. I also had to exclude commons-logging from any dependency that includes it, e.g. spring-core as shown.
<properties>
<spring.version>4.0.0.RELEASE</spring.version>
<log4j.version>1.2.17</log4j.version>
<slf4j.version>1.7.5</slf4j.version>
</properties>
<dependencies>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>${log4j.version}</version>
