You can also run MVN – e package and MVN – x package on the command line under the project directory folder according to the prompt, and I see that specific error messages will be printed on the Internet to point out the problematic jar packages. However, it takes too much time to download all jar packages again, so I didn’t try.

Then enter the directory,/MNT/D/develop/mavenrepo/COM/Alibaba/fastjson/1.2.44 /, and find that there is a aether-fb0089ce-dff1-4256-9ccc-a2bb768c48f7-fastjson-1.2.44.jar.sha1-in-progress file in it. Delete all files in the directory and repackage. Success!

Summary: this problem is also the cause of Maven’s error in downloading jar. Most of the problems encountered are the cause of Maven’s error in downloading jar package.
