I have a class like this (it’s a java class in eclipse, under a Maven project):

public class SolrJ
{
    public static void main( String[] args )
    {
        String url = "http://localhost:8983/solr";
        try {
            SolrServer server = new CommonsHttpSolrServer(url);
            server.deleteByQuery( "*:*" );
        } catch (MalformedURLException ex) {
            ex.printStackTrace();
        } catch (SolrServerException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}

After running this class I got the following exception:

Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory
    at org.slf4j.LoggerFactory.staticInitialize(LoggerFactory.java:83)

    at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.<clinit>(CommonsHttpSolrServer.java:77)
    at ultimo.solrJ.SolrJ.main(SolrJ.java:19)

My pom.xml looks like this:

<dependencies>
    <dependency>
