** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
Volver a agregar el plugin a app.yml provoca el error anterior. Quitarlo inmediatamente hace que la compilación funcione de nuevo. Este plugin parece ser el único problema.
Soy consciente de que estamos en una versión desactualizada y que está en la hoja de ruta actualizar. Solo quería señalar que, aunque no hemos cambiado la versión que estamos ejecutando, 3.5.4 pasó de compilar bien (con el plugin) a no compilar más con el plugin y no parece que tengamos forma de recuperar la funcionalidad del plugin (a través del plugin o en el núcleo).
