Building the pigtail example cordapp

[VladislavIvanov]

I am trying to build the pigtail example cordaap with the ./gradlew deployNodes command.

The execution fails with the following error:

* What went wrong:
Could not resolve all files for configuration ':cordapp:compileClasspath'.
> Could not resolve io.bluebank.braid:braid-corda:3.1.3.
  Required by:

            > Permission denied (connect failed)

Any idea why this error occurs?

Thanks!
