Question

I'm facing a problem when I want to build my Spring project. The error that I'm getting from eclipse is:

I tried every solution that I found in stackoverflow, but no result.

Thank you in advance for your help regards

You should remove the <scope>compile</scope> from slf4j (you need it at runtime too). — Elliott Frisch

You need to add another dependency to solve the issue.

  <!-- Logging with SLF4J & LogBack -->
  <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>${slf4j.version}</version>
      <scope>compile</scope>
  </dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>${slf4j.version}</version>
</dependency>

Add another dependency. Hope it will help you.
