This error occurs when you build Maven using eclipse. It may be because the corresponding Pom is generated after the version of the maven plug-in eclipse is updated. the XML file is not updated. You only need to upgrade the version in version. I upgraded to 2. 1. of course, if the maven plug-in version in your eclipse is not the latest, but the latest Pom is used. XML may also cause these errors. It is okay to adjust the version anyway.
