Formatting inconsistent when both <tabs> and <spaces> indentation rules are present

Start by reproducing the behavior with the Maven plugin configuration in the issue, focusing on the two Java blocks and the src/main/java//*.java and src/test/java//*.java includes. Inspect how the Maven configuration handles multiple indentation rules; done means Java files are formatted consistently when both rules are present, with the up-to-date debug message behaving as expected.

I'm encountering inconsistent formatting behavior when both blocks — one tabs true and another with spaces true — are defined under the Spotless configuration in a Maven project.

Some Java files are formatted, some are skipped, and others show partial formatting. When I remove one of the two blocks, the behavior becomes consistent.
I keep getting this debug log
[DEBUG] Spotless will not format an up-to-date file:
