我有一个这样的类（它是 Eclipse 中的一个 java 类，在一个 Maven 项目下）：
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();
}
}
}
运行这个类后，我得到了以下异常：
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)
我的 pom.xml 看起来像这样：

有人可以帮忙解决我的问题吗？我已经通过 Internet 搜索，但找不到任何方法来解决我的问题。
