Integración de Jenkins con BitBucket

El asunto del titulo parece bastante simple y de hecho lo es. Pero al intentar realizar un fetch de una aplicación alojada en bitbucket a través de autenticación basada en HTTPS, obtuve los siguientes errores:

En los foros de internet la respuesta a este error era siempre la misma. Desde la versión 1.4.0 el issue fué solucionado. Nosotros teníamos instalada la versión 2.2.2 y aún así no funcionaba. Intentamos muchas cosas hasta que decidimos bajar la versión del plug-in Git de Jenkins a la versión 1.4.0 y se hizo la luz. Al parecer la ultima versión del plug-in tiene un problema con la autenticación HTTPS.

Los desarrolladores no consideramos el mal que podemos causar al entregar liberaciones de producto a producción sin asegurar adecuadamente la calidad. Fué 1 semana de trabajo que nos retrasó en cierta medida el proyecto. :-(
