Java : compile error

Question

我已经创建了一个包:

路径 :/home/myid/py_ejb
文件:XmppMnager.java

package xmpp;

import org.jivesoftware.smack.Chat;
public class XmppManager {
}

编译为

javac -d . -classpath .:smack.jar XmppManager.java

文件:XmppTest.java

import xmpp.*;

public class XmppTest {

    public static void main(String[] args) throws Exception {

        String username = "testuser1";
        String password = "testuser1pass";

        XmppManager xmppManager = new XmppManager("myserver", 5222);

..}

编译为

$ javac  -classpath .:smack.jar:./xmpp XmppTest.java 
XmppTest.java:10: cannot access XmppManager
bad class file: RegularFileObject[./xmpp/XmppManager.class]
class file contains wrong class: xmpp.XmppManager
Please remove or make sure it appears in the correct subdirectory of the classpath.
        XmppManager xmppManager = new XmppManager("myserver", 5222);
        ^
1 error

我尝试了很多方法来解决这个编译问题，但它就是没有消失

Answer 1

将源文件移动到名为xmpp 的文件夹中，使包名称与文件夹名称相匹配
