您是我的最后希望。我写了小机器人电报。它的工作原理完美,但我无法将其构建为可执行的jar文件。每次我尝试在服务器上执行jar文件时,都会收到错误消息:
Error: Could not find or load main class com.praetorian19.MainIni
我知道我以错误的方式提到了课堂路径。我尝试以不同的方式提及它,但这没关系。错误是一样的。请查看我的MVN项目xml和Idea项目结构的一些屏幕截图。我认为我在pom或结构上有错误。
我尝试以多种方式编写类路径。但是结果一样 我尝试在两个平台上都构建jar-Win / Lin,相同

错误:找不到或加载主类com.praetorian19.MainInit 当我尝试在服务器上执行jar时
我也尝试
praetorian19.MainInit
但结果相同
答案 0 :(得分:0)
问题是您在com.praetorian19.MainInit
中将主类定义为maven-assembly-plugin
,这意味着MainInit
类应该在软件包com.praetorian19
中。
但是,当查看IDEA项目结构时,您的MainInit类位于默认包中,因此在执行Could not find or load main class com.praetorian19.MainIni
时会给出错误jar
。
要解决此问题,请创建一个包com.praetorian19
,并将您的MainInit
类移动到该package
中,并将包声明声明为package com.praetorian19;
