Comencé un proyecto donde tengo que usar un svn externo (estoy bajo un proxy). Cuando puse la url en el proyecto de configuración, Jenkins no puede acceder al repositorio, así que llené la credencial (url del repositorio, nombre de usuario y contraseña) pero aquí está el error:

FAILED: svn: E175002: OPTIONS /.../trunk/www failed

En C: \ Windows \ System32 \ config \ systemprofile \ AppData \ Roaming \ Subversion \ server, el proxy está configurado y en Jenkins, puedo instalar / actualizar complementos.

El svn url está en https y puedo acceder a él con credenciales en un navegador.

De forma predeterminada, la versión svn utilizada en Jenkins es 1.4, incluso con la versión 1.7, es imposible acceder a este servidor svn.

El servidor es un Windows 7 de 64 bits y esta es la última versión de Jenkins.

Dónde está el problema ?

Gracias
