Does not match a valid id pattern
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'artifactId' with value 'Maven_01_test' does not match a valid id pattern.
Cause of error
The format of the gav in the pom file is wrong. There can only be numbers, letters, and underscores in the gav tag, and no spaces or Chinese can appear.
The vast majority of reasons are that there are Chinese or spaces in the <artifactId tag.
<artifactId>Maven_01_test</artifactId>
Solution
Modify the gav tag of the pom file, change the Chinese to English, remove the extra spaces, and refresh the pom file.
example:
Change the Chinese "test" in the tag to English "test"
<artifactId>Maven_01_test</artifactId>
