1.idea fast new spring boot project
2. related problems encountered Screenshot (various packages issue)
So, begin Baidu, check solution following is a summary, there is a hope that is right for you.
1. The main issue is pay attention to your configuration idea
Look at the maven and correct jdk
2. refresh try to re-download
3. I walked a little detour, again pulled maven, and check their configuration issues. (Main maven is a bit strange, it is deleted)
Here I changed the B operating the computer to do new projects, everything is normal, so I put my computer maven local repository and deleted, pull B computer replaced, re-operation, still far from being given to the face, headache .
Work, and then every other day I changed the C computer operation, the same error. After checking the basic configuration issues, see which packages have a problem, go to the local warehouse will make corresponding packet delete re-download maven, OK the. (It would be a solution) I did the same operation is still not at their computers, alas, I was a bit skeptical life.
4. Then I changed settings.xml maven, replacing what url, there is always a right for you.
