1. Background:
Yesterday, my colleague added hadoop dependencies to a project. After pulling the code, the service kept prompting that the jar package does not exist, but there is a local jar package library. Very annoyed, after trying many methods to no avail, finally saw the sunny day again.
2. There is no problem with the hadoop package:
1: First click MAVEN on the right side of the idea, find the wrong item, and click "M".
2: Enter: mvn idea:idea
3: Wait for confirmation, and then run it.
3. Summary.
Problems are like obstacles, the more they are solved, the smoother the road. I have been working overtime recently, and some blog series are more forgiving.
