[robertpanzer]

The build is broken at the moment with errors like this:

./gradlew clean build

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'asciidoctorj'.

Happens both locally after clearing the cache, and on the CI.

@ysb33r Do you have an idea what could be the problem here?

If I upgrade to the latest alpha, 2.1.0-alpha.2 I get similar issues:

./gradlew clean build
