Caso esteja usando o PowerShell

Ao tentar executar o comando:

mvn archetype:generate -DgroupId=br.com.alura.maven 
    -DartifactId=produtos 
    -DarchetypeArtifactId=maven-archetype-quickstart 
    -DinteractiveMode=false

Recebi o erro:

Após pesquisar bastante encontrei que esse é um problema envolvendo o PowerShell, no caso de tentar executar o comando como mostrado na aula é necessário acrescentar aspas duplas aos argumentos:

mvn archetype:generate "-DgroupId=br.com.alura.maven" 
    "-DartifactId=produtos" 
    "-DarchetypeArtifactId=maven-archetype-quickstart" 
    "-DinteractiveMode=false"
