后无法找到或加载主类,当我设置我的pom.xml时,我的应用程序仍然无法运行,说它无法找到或加载主类。 我安装我的pom.xml作为陈述hereMaven在正确设置插件
我的pom.xml:

我用命令MVN清洁编译组件:单将应用程序打包,然后用java的运行 - 罐子outputedJar.jar
这是MANIFEST.MF这是罐内,说:
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: xxxx
Build-Jdk: 1.8.0_121
Main-Class: com.example.EditPropertiesFile.Main
然而,当我跑,我得到一个错误:
Error: Could not find or load main class com.example.EditPropertiesFile.Main
我不知道还有什么我可以试试,因为我有这么尝试了所有在各种答案,他们似乎都解决其他一些问题。
编辑: 输出运行时,命令:

里面的jar文件没有文件Main.java
我的项目的结构:
我现在编辑的问题。 Main.java不在我输出的jar中。 –
我不确定目录结构是否是问题。我编辑了问题,在最后给出了项目结构图 –
,如果您使用命令行中的mvn,那么您可能需要确保目录结构符合mvn默认值。也许你可以尝试一下我刚才提到的结构,如果还没有完成的话。 – Sharman25
