New Maven project– pom.xml report errors

Welcome to blog using the Markdown editor
Sometimes when we create new Maven projects, the pom.xml file likes to report errors (especially on the first line!). . However, our Settings configuration and so on are all fine. You may be confused at this point, but that’s okay. Follow these steps and give it a try. It might solve your problem.
The reason: Eclipse integrated Maven had issues (version issues or site access issues), and the newly installed Maven was not successfully added to the M2e plug-in
The solution is as follows:
Step.1 Go to the official website to download the appropriate version of Maven and store it in the appropriate path (or check the missing JAR file in the report — the corresponding error message will provide the URL to download the missing file — copy it to the appropriate path in the local repository).
Step.2 Open Eclipse Preferences -> Maven-> UserSettings changes the Global Settings and UserSettings to conf/settings.xml in Maven that you just downloaded
Step. 3 the Eclipse preferences – & gt; Maven-> * * * Click on Add to Add the Maven folder you just downloaded, and then check your own version instead of using the built-in one
Step.4 After the above two steps, you have successfully integrated the Maven version you downloaded with Eclipse, and then right-click on the project that reported an error before, and right-click Run As ->; Maven clean, then Run As ->; Maven install

ep.5: project right-click ->; Maven-> The Update Project step takes a bit of time and you can see if the Update has been completed by looking at the bottom right corner of the screen.
