1.Failed to read artifact descriptor for

When you create a Maven project in IDEA and introduce dependencies in pom.xml, you sometimes get an error Failed to read artifact descriptor for xxx.

This may be due to a problem with the configured image. The resolution process is as follows:

(1) add a new profile to set the mirror source

Add the following to the settings.xml configuration file under the C:\ Users\ Administrator\ .m2 directory (Lenovo is C:\ Users\ LENOVO\ .m2):

Alimaven aliyun maven http://maven.aliyun.com/nexus/content/repositories/central/ central

If this file does not exist before, you need to create the file first, and then configure it as follows:

Alimaven aliyun maven http://maven.aliyun.com/nexus/content/repositories/central/ central

Ali's mirror source is set up here.

(2) IDEA to operate

After IDEA opens the project, select Maven on the right, click open, and then open Lifecycle, as follows:

You can see clean, validate, compile, and so on.

Right-click clean and select Run 'project [clean]' (project is the actual name of the project), as follows:

Right-click install, and select Run 'project [install]', as follows:

This process takes a long time. If you encounter a situation where a jar package cannot be downloaded, you can download it manually and place it in the local C:\ Users\ LENOVO\ .m2\ repository directory.

Reload all Maven projects

Because the Maven source is reconfigured, Maven needs to reload the dependency, as follows:

Restart

Since the dependencies set may not take effect immediately after the project is reloaded, you may need to restart IDEA, as shown below:

Wait for the restart, and then check. If you still can't import the dependency, you can choose to restart your computer and try again.
