The problem ONLY occured when I added library files to the artifact, and without external libraries the jar executed fine. 仅当我将库文件添加到工件时才发生此问题，并且在没有外部库的情况下，jar可以很好地执行。
The process I followed to create the artifact was as follows : File -> Project Structure -> Artifacts -> add Jar -> from modules with dependencies... -> After The Next Windows the following was shown 我遵循的创建工件的过程如下：文件->项目结构->工件->添加Jar->来自具有依赖项的模块...->在下一个Windows之后，显示以下内容
And my problem was fixed when I removed all the items that had 'Extracted" prefixes. I also added The Library File to look like this -> Which made my jar with library dependencies work again 而且，当我删除所有带有“ Extracted”前缀的项目时，我的问题已得到解决。我还添加了“库文件”，使其看起来像这样->这使具有库依赖项的jar再次工作 ] 2
