我想创建一个连接到我的Openfire服务器的简单XMPP客户端。我在运行代码时遇到以下问题。我在创建使用smack的XMPP客户端时遇到困难4.2 Openfire
代码：
public void setConnection() {
try {
XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
config.setUsernameAndPassword(userName,password);
config.setResource("temp");
config.setXmppDomain("undercrroft");
AbstractXMPPConnection connection = new XMPPTCPConnection(config.build());
connection.connect();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (SmackException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
}
错误：
Information:java: Errors occurred while compiling module 'Messenger'
Information:javac 1.8.0_121 was used to compile java sources
Information:16/4/17 1:52 AM - Compilation completed with 2 errors and 0 warnings in 871ms

Error:(29, 19) java: cannot access org.jxmpp.jid.DomainBareJid

这是我进口：
import org.jivesoftware.smack.AbstractXMPPConnection;
import org.jivesoftware.smack.SmackException;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.tcp.XMPPTCPConnection;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;
感谢。
