1. The idea system error message is as follows:
Cannot access public (https://maven.aliyun.com/repository/public) in offline mode Try running Maven import with -U flag (force update snapshot)
2.Troubleshooting ideas
When I saw this error message, the first thing I thought of was whether the maven environment variables were configured correctly. However, after some inspection, I found that there was no problem with the maven configuration. Then I thought about whether maven in the idea was not configured correctly because the idea was not configured. Correct, it is very likely that the above error will occur. However, I checked the idea configuration and there is no problem. There is also no problem when I check the Alibaba Cloud image;
3. Resolved successfully
Later, after a series of checking various configurations, I found that it was caused by a setting in the idea. Just remove the √ for offline work and it would be fine.
Finally, the package was successfully packaged and the successfully deployed picture will not be released.
Summarize
The solution is as follows:
1. Whether the maven environment variables are configured correctly;
2. Whether the idea configuration is correct;
3. Check the maven warehouse configuration;
4. Check whether the mirror path has changed or other conditions;
