#1

Ola Pessoal,

sou iniciante no maven, estou estudando esta ferramenta para buscar conhecimento etc… , poém estou com alguns problemas, cheguei a instalar a versão:

[quote]
C:>mvn -version
Apache Maven 3.0.3 (r1075438; 2011-02-28 14:31:09-0300)
Maven home: C:\bin\apache-maven-3.0.3\bin…
Java version: 1.6.0_23, vendor: Sun Microsystems Inc.
Java home: C:\Program Files\Java\jdk1.6.0_23\jre
Default locale: pt_BR, platform encoding: Cp1252
OS name: “windows 7”, version: “6.1”, arch: “amd64”, family: “windows” [/quote]

Porém quando crio um simples projeto apresenta o seguinte erro:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.0:create (default-cli) on project Sicad: Error creating from archetype: Unable
to add module to the current project as it is not of packaging type ‘pom’ -> [Help 1]

Alguem pode me ajudar com esse problema? Por favor?
Agradeço!!!

#2

Tentou usar como ele recomenda na linha 9

mvn archetype:generate ...

?

#3

cara se está apenas estudando continue executando por linha de comando,
agora se quer desenvolver rápido baixa o plugin m2eclipse ou usa o netbeans que já vem com suporte ao maven.

#4

Luciano valeu pela dica, mas vou tentar mais um pouco.

Ruivo, tentei utilizar da forma que você falou e apresentou este erro:
