gradle-plugins: Failed build when offline

I’m still getting issues with 3.3.1 javadoc-links when building offline. I’m now getting an exception trace looping as like below.

It does not mater if I try gradlew -x javadoc or gradlew --offline, it still fails the same way.

Is it possible to change the plugin to not take any action of -x javadoc is passed?

It would be good if you tested offline and purged the DNS catch.
