SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error

Question

I can also confirm this error.

Workaround: is to use external maven inside m2eclipse, instead of it's embedded maven.

That is done in three steps:

1 Install maven on local machine (the test-machine was Ubuntu 10.10)

mvn --version

Apache Maven 2.2.1 (rdebian-4) Java version: 1.6.0_20 Java home: /usr/lib/jvm/java-6-openjdk/jre Default locale: de_DE, platform encoding: UTF-8 OS name: "linux" version: "2.6.35-32-generic" arch: "amd64" Family: "unix"

2 Run maven externally link how to run maven from console

> cd path-to-pom.xml
> mvn test

3 inside m2eclipse: switch from embedded maven to local maven

• find out where local maven home installation dir is (mvn --version, or google for your MAVEN_HOME, for me this helped me that is /usr/share/maven2 )
• in eclipse Menu->Window->Preferences->Maven->Installation-> enter that string. Then you should have switched to your new external maven.
• then run your Project as e.g. "maven test".

The error-message should be gone.

There is a documentation in SLf4J site to resolve this. I followed that and added slf4j-simple-1.6.1.jar to my aplication along with slf4j-api-1.6.1.jar which i already had.This solved my problem

slf4j

If you are using Gradle add this:

dependencies { 
... 
compile "org.slf4j:slf4j-simple:1.7.9" 
... 
}

Had similar error with the same result with Gradle and was able to solve it by following:

//compile 'org.slf4j:slf4j-api:1.7.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-slf4j-impl', version: '2.1'

Out-commented line is the one which caused the error output. I believe you can transfer this to Maven.

Paste this code to your pom.xml file. It works for me.

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.6.1</version>
    <scope>test</scope>
</dependency>

You haven't specify version in your maven dependency file may be thats why it is not picking the latest jar
As well as you need another deppendency with slf4j-log4j12 artifact id.
Include this in your pom file

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.5.6</version>
</dependency>

Let me know if error is still not resolved
