Description

my code is

@Mojo(name = "hello",requiresProject = false)
public class HelloWorldMojo extends AbstractMojo{

    @Override
    public void execute() throws MojoExecutionException,MojoFailureException{
        String[] argStrings = { "Hello world" };
        FormattingTuple formattingTuple = MessageFormatter.arrayFormat("{}", argStrings);
        getLog().info(formattingTuple.getMessage());
    }
}

when i run my plugins , show me result:

Caused by: java.lang.NoClassDefFoundError: org/slf4j/helpers/MessageFormatter

*and i also see that, in maven "META-INF/maven/extension.xml" file ,
here is slf4j exportedArtifact config:*

    <exportedArtifact>org.slf4j:slf4j-api</exportedArtifact>

and in org.apache.maven.classrealm.DefaultClassRealmManager.isProvidedArtifact(Artifact) line 167 , has code validator

if ( artifacts != null )
        {
            for ( Artifact artifact : artifacts )
            {
                if ( !isProvidedArtifact( artifact ) )
                {
                    artifactIds.add( getId( artifact ) );
                    if ( artifact.getFile() != null )

                }
            }
        }
