異常實例CommonsHttpSolrServer

當我有這樣一個類（這是Eclipse的一個Java類，一個Maven項目下）：異常實例CommonsHttpSolrServer

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.slf4j.LoggerFactory.<clinit>(LoggerFactory.java:73) 
    at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.<clinit>(CommonsHttpSolrServer.java:77) 
    at ultimo.solrJ.SolrJ.main(SolrJ.java:19)

：

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(); 
     } 
    } 
}

運行這個類，我得到了以下異常後

我的pom.xml看起來是這樣的：

<dependencies> 
    <dependency> 
     <groupId>junit</groupId> 
     <artifactId>junit</artifactId> 
     <version>4.8.1</version>

    </dependency>

     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-simple</artifactId> 
     <version>1.5.6</version> 
    </dependency>

任何人都可以幫忙解決我的問題嗎？我通過互聯網進行了訪問，找不到解決問題的方法。
