Create a Maven project in Eclipse complains "Could not resolve archetype"

i found the easiest way was to just remove/delete the .m2 folder and recreate it, putting back your settings.xml configuration details(if applicable).

Adding the following inside "mirrors" section in the user setting.xml file worked for me.

<mirror>
  <id>ibiblio.org</id>
  <url>http://mirrors.ibiblio.org/maven2</url>
  <mirrorOf>central</mirrorOf>
</mirror>

Assuming that you have your proxy settings correct, you may have missed out pointing Eclipse to the intended settings.xml file. This happens often when you have both Maven installed as a snap in, and an external installation outside Eclipse. You need to tell Eclipse which Maven installation it should use, and which settings.xml file it should be looking for.

First check that the settings.xml file contains your proxy settings.

Next, check that the user settings.xml file here contains your proxy settings.

If you have made any changes, restart Eclipse.

I fixed this problem by following the solution to this other StackOverflow question

I had the same problem. I fixed it by adding the maven archetype catalog to eclipse. Steps are provided below: (Please note the https protocol)

1. Open Window > Preferences
2. Open Maven > Archetypes
3. Click 'Add Remote Catalog' and add the following:
   • Catalog File: https://repo1.maven.org/maven2/archetype-catalog.xml
   • Description: maven catalog
