java - idea maven install is successful but dependence is not displayed

Question

The flume source code of the official website is opened with idea. The install passes, but dependence is not displayed. All imports display unused import statement. Tried to reimport and restart, but it is ineffective. Please help with the solution.

Answer 1

The problem has been solved. It seems to be a problem with idea. It was successfully solved by using mvn -U idea:idea. Although I still don’t know what the problem is, this command works.
