I want to build a simple project using a existing archetype. But I can\'t run mvn archetype:generate as it keeps telling me the following information
The command you should be using to generate a project with an archetype is...
mvn archetype:generate
The command you posted in your question was wrong (missing the first 'e' in archetype). I assume this is just a typo in SO though because the error you posted had archetype spelled correctly.
I believe this error will occur if you are trying to execute this command from a directory that already has a pom.xml file in it. It will try to find an archetype plugin configuration inside the existing pom.xml file.
Try the command again in an empty directory, or at least in one that doesn't have a pom.xml file and it should work.
