Maven-plugin-plugin:descriptor goal fails when I want add Log4j to dependencies

Question

I have a simple Maven plugin in which I want to use library Log4j. But when I call the command mvn clean install, I get this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor (default-descriptor) on project test-maven-plugin: Execution default-descriptor of goal org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor failed.: NullPointerException -> [Help 1]

My pom.xml:

            <version>2.11.1</version>
        </dependency>
    </dependencies>
</project>

And I have one class Main:

package cz.test.maven;
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecutionException;
import org.apache.maven.plugins.annotations.Mojo;

@Mojo( name = "sayhi")
public class Main extends AbstractMojo
{
    public void execute() throws MojoExecutionException
    {
        getLog().info( "Hello, world!" );
    }
}

When I remove Log4j from dependencies, the plugin will build without any problems. The problem is only with Log4j, other libraries (for example Jsoup) are imported properly. How can I fix this issue?

I tried this, but it didn't help me: https://stackoverflow.com/a/18999647/10431161
