Log4j slf4j not working

I am trying to get logging working in my Apache Camel project. I have tried the following:

VM args In eclipse I have added tried the following VM args: -Dlog4j.configuration=log4j-/resources/log4j.properties -Dlog4j.debug=true

Properties file on class path I have doubled checked that log4j.properties is on the class path

My java looks like this:

Logger LOG = LoggerFactory.getLogger(CamelMain.class);
LOG.info("starting");

My pom contains the following: 

<dependency>
          <groupId>org.apache.camel</groupId>
          <artifactId>camel-core</artifactId>
          <version>2.14.1</version>
        </dependency>
        <dependency>
          <groupId>org.apache.camel</groupId>
          <artifactId>camel-beanio</artifactId>
          <version>2.14.1</version>
        </dependency>
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.6.1</version>
        </dependency>       
         <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.2</version>
          </dependency>
          <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.2</version>
          </dependency>

Any ideas why the logging is not working?

Update / Solution

I needed to add the following:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.6.1</version>
</dependency>

Add following dependencies if you want to use slf4j over log4j and remove the dependencies for org.apache.logging.log4j and commons-logging.

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.6.1</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.6.1</version>
</dependency>
