Bom dia, estou tentando usar a api Gson junto com a ultima versão do vraptor.
No entanto, toda vez que faço o registro abaixo no web.xml, a aplicação não sobe.

<context-param>
		<param-name>br.com.caelum.vraptor.packages</param-name>
		<param-value>
                     br.com.caelum.vraptor.deserialization.gson,
                     br.com.caelum.vraptor.serialization.gson
        </param-value>
</context-param>

Segue abaixo o stack:

Isso é um bug que foi corrigido… você pode usar o 3.5.2-SNAPSHOT?

Consegui resolver o erro ao startar o tomcat, eu estava usando uma versão mais antiga do vraptor e não me dei conta.

Agora o problema ocorre que mesmo registrando o gson no web.xml, o vraptor continua usando o xstream pra deserializar o json.

E como se não bastasse, o xstream não está conseguindo deserializar.

Lucas, posso usar o snapshot sim, mas tu tens alguma dica pra adicioanar ele pelo ivy ?

Se não vou colocar ele na mão mesmo.

Com o ivy você não consegue configurar repositórios? Se sim, você só precisar configurar o repositório de Snapshots e pronto.

Tudo certo agora.

Construi meu projeto com o vraptor-scaffold usando o ivy como gerenciador de dependencias.
No entanto, ao construir o projeto pelo ant, por algum motivo o projeto não compila pois não reconhece os métodos do Hamcrest (MethodNotFoundException) e não reconhece uma classe do jar apache commons-codec.
Detalhe: o Hamcrest está no classpath da aplicação e o commons-codec quando adicionado no ivy, da erro de dependência…

Foi um dia difícil hoje.
