Java JVM错误:经过多次调试后，无法找到或加载主类

Question

我尽我所能解决了这个问题，做了所有的研究。还是解决不了。我是不是错过了什么？

这是我当前的目录

$ pwd
/Applications/apache-tomcat-9.0.8/webapps/masterwarehousing_topdown/generatedWrappers/16451886466
$ ls -la
-rw-r-----   1 user  staff  7841 Jul 12 16:50 XMLEliteExtraction16451886466.java

在这个文件中，类不在任何包中：

import java.io.*;
import java.net.*;
import java.util.Vector;
import edu.gatech.disl.inforetrieval.*;
import edu.gatech.disl.inforetrieval.seqalignment.*;
import edu.gatech.disl.inforetrieval.codegeneration.WrapperTemplate;
import edu.gatech.disl.qr.util.Base64;
public class XMLEliteExtraction16451886466 extends WrapperTemplate {
public XMLEliteExtraction16451886466() {
....
public static void main(java.lang.String[] args) { ....

我用成功编译了这个

在我当前的目录中。

但是当我用jvm加载它时，我得到的是：

$ java -cp /Applications/apache-tomcat-9.0.8/webapps/masterwarehousing_topdown/generatedWrappers/16451886466 XMLEliteExtraction16451886466
Error: Could not find or load main class XMLEliteExtraction16451886466

此处相同：

$ java XMLEliteExtraction16451886466
Error: Could not find or load main class XMLEliteExtraction16451886466

Answer 1

您可能需要指定完整的限定类名(好吧，不适用于没有包的情况(，并检查该类是否有一个由提供的带有签名、返回类型和修饰符的主方法

public static void main(String[](

参见What dos"；无法找到或加载主类"；意思是

Answer 2

尝试

java -cp ./:/Applications/apache-tomcat-9.0.8/webapps/masterwarehousing_topdown/generatedWrappers/16451886466 XMLEliteExtraction16451886466
