Eu comecei um projeto onde eu tenho que usar um svn externo (estou sob um proxy). Quando eu coloco o url no projeto de configuração, o Jenkins não pode acessar o repositório, então eu preenchi as credenciais (url do repositório, nome de usuário e senha) mas aqui está o erro:

Em C: \ Windows \ System32 \ config \ systemprofile \ AppData \ Roaming \ Subversion \ server, o proxy está configurado e no Jenkins, eu posso instalar / atualizar plugins.

O svn url está em https e eu posso acessá-lo com credencial em um navegador.

Por padrão, a versão do svn usada no Jenkins é 1.4, mesmo com o 1.7, impossível acessar este servidor svn.

O servidor é um Windows 7 de 64 bits e esta é a última versão do Jenkins.

Onde está o problema ?

Obrigado
