Failed to load class “org.slf4j.impl.StaticLoggerBinder” error
<p>I'm opening this post after I couldn't find a solution in the post:
<a href="https://stackoverflow.com/questions/11587627/failed-to-load-class-org-slf4j-impl-staticloggerbinder-error">Failed to load class &quot;org.slf4j.impl.StaticLoggerBinder&quot; error</a></p>

<p>I also opened a Maven project in IntelliJ and got the following error after choosing the option 'redeploy' in tomcat7 plugin:</p>

<blockquote>
  <p>SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
  SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J:

<p>In the attached link, it was recommended to go to File-> Project Structure -> Artifacts and check for errors. This is what I see:

<p>I also have the following dependencies in pom.xml file:</p>

<pre><code>        &lt;dependency&gt;
            &lt;groupId&gt;org.slf4j&lt;/groupId&gt;
            &lt;artifactId&gt;slf4j-api&lt;/artifactId&gt;
            &lt;version&gt;1.7.5&lt;/version&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;org.slf4j&lt;/groupId&gt;
            &lt;artifactId&gt;slf4j-log4j12&lt;/artifactId&gt;
            &lt;version&gt;1.5.6&lt;/version&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
            &lt;groupId&gt;org.slf4j&lt;/groupId&gt;
            &lt;artifactId&gt;slf4j-simple&lt;/artifactId&gt;
            &lt;version&gt;1.7.21&lt;/version&gt;
        &lt;/dependency&gt;

<p>Can you please help me finding the error? </p>
