[upeuker]

Using the gradle plugins in version 2.2.0, the asciidoctor and asciidoctorPdf - tasks fail running the build using gradle 5.5, no problem with gradle 5.4.1.

Here ist the failure stack:

Thank you for raising this. I have not had a chance to test against 5.5. yet, so will add it to compatibility tests.

[ysb33r]

Found the issue. Rolling up a fix that will be in 2.3.0.

[ysb33r]

Merged. Will be in 2.3.0 & 3.0.0.alpha-4 releases.

[jgoldhammer]

Any chance to backport this to 3.0.0-alpha.3 and release a new version with this fix?

Workaround: stick with an earlier gradle version until alpha.4 is release (gradle 4.8 worked for me).
