Description Resource Path Location Type Unknown pom.xml /decision line 1 Maven Configuration Problem

Solution:
Add the following line, and then execute maven update, just fine, I don’t know why.

<packaging>war</packaging>

E.g:

<groupId>com.xxx</groupId>
<artifactId>xxx</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
