我有一个类允许我使用LDAP进行身份验证。当我在只有一个类的项目中运行此代码（出于测试原因）时，我没有问题，并且它按照预期返回一个布尔值，但是当我在工作中的项目中运行它时，我得到了以下错误：LDAP身份验证问题：java.lang.IncompatibleClassChangeError
java.lang.IncompatibleClassChangeError: Class org.apache.mina.filter.codec.ProtocolCodecFilter does not implement the requested interface org.apache.mina.core.filterchain.IoFilter
这就是让我身份验证的方法：
public static void autenticarUsuario(String usuar, String password) throws LdapException, CursorException{
Dn user = Dn.EMPTY_DN;
try{
BasicConfigurator.configure();
LdapConnectionConfig config = new LdapConnectionConfig();
config.setLdapHost(SERVER_IP);
config.setLdapPort(PORT);
config.setName("uid=ldapsearch,ou=System,ou=Users,dc=fiec,dc=espol,dc=edu,dc=ec");
config.setCredentials(CREDENTIALS);
conn = new LdapNetworkConnection(config);
}catch(Exception e){
}
String s1 = usuar;
String s2 = password;
//System.out.println("Nombre: "+s1+" Contra: "+s2);
try {
conn.bind();
System.out.println(conn.isAuthenticated());
// Create the SearchRequest object
SearchRequest req = new SearchRequestImpl();
req.setScope(SearchScope.SUBTREE);
req.addAttributes("*");
req.setTimeLimit(0);
req.setBase(new Dn("ou=Users,dc=fiec,dc=espol,dc=edu,dc=ec"));
req.setFilter("(uid="+ s1 +")");
// Process the request
SearchCursor searchCursor = conn.search(req);
while (searchCursor.next())
{
Response r = searchCursor.get();
if(r instanceof SearchResultEntry){
Entry re = ((SearchResultEntry) r).getEntry();
user = re.getDn();
}
}
conn.bind(user, s2);
//return(conn.isAuthenticated());
inLDAP = conn.isAuthenticated();
} catch (InvalidConnectionException ex) {
//System.out.println(ex);
}
catch (LdapException e) {
e.printStackTrace();
} catch (CursorException e) {
e.printStackTrace();
}
inLDAP = false;
}
的项目中，我的工作是的JavaFX应用程序，但这种方法被称为一类这不会从应用程序扩展（只是验证用户凭据的Java代码）。
这是堆栈跟踪：

这些都是我工作的库：

我不知道为什么会这样，我会感谢提前任何帮助
