• Find conflicting packages
  Click the button in the picture , Or use the shortcut key Ctrl+Alt+Shift+u
  
  As long as there is a red line , It means that there are conflicting packages （ Here is a brief explanation , Generally, the probability of package conflict in development is not much , But like me , What kind of HugeGraph, This niche project , It's very likely that ）
  
  Click on maven The upper left corner of the dependency tree ,Show Conflicts/Duplicates, All conflicting dependencies can be displayed
  
  After clicking, my display is
  
• Choose a version jar Package to delete
  Here select one to delete jar package , The selection criteria are Choose a higher version or lack some methods jar Delete , For example, we should use the new feature method of high version , Then delete the lower version jar, If you don't use new methods , Just delete the higher version like me ,（ Don't worry about deleting mistakes ）

• Finally, I would like to thank these bosses who found the problem
  I am using HugeGraph Figure database is very small , all 2021 了 , There is no official version , If something goes wrong, you can't find it , Here is an important lesson , Read more official documents , If something goes wrong, we can't find it. We can consider Inquire about Github Of Issues, Of course, we'd better mention it ourselves , You can also view the history of project updates , Maybe your problem is in the new version fix 了 , End
