Description

I generated a basic Spring Boot gradle project on http://start.spring.io (choose gradle project type then press generate, unzip downloaded archive).

I opened the generated project in NB11.

The following exception pops-up almost immediately after opening:

The resulting project is unloadable and unbuildable.

A notification is also generated with a warning telling:

null
Could not run build action using Gradle installation 'null'

The latter may be a distinct problem.

On the console there is also another exception thrown (reporting essential part):
