I would like to ask my predecessors why I have been stuck in a maven project.

Eclipse does happen sometimes.

Sometimes stuck in “Error report”, restart the solution.
Sometimes the card is downloading a package and using VPN to solve it.
If both methods are used or not, redeploy eclipse,

These three methods basically solved the problem. As to why the jam occurred, it is still unknown.
