Project Isolation: Project cannot access task dependencies directly

[consp1racy]

buildDependencies.getDependencies(null) isn't compatible with Project Isolation.

I'm looking for a PI-compatible alternative API. Or waiting for the Gradle team to make the exiting API compatible ^^

Reading properties from parent projects can be prevented by assigning same-named extras on every project using KSP. That's another problem, that can already be worked around.

+1 to this issue. Bellow a configuration cache reports that lists cannot access task dependencies directly issues as well as cannot dynamically look up a property in the parent project on ksp.experimental.processing.model and a bunch of others.

[ansman]

The cannot dynamically look up a property in the parent project errors have been fixed in #2034

[solonovamax]

The cannot dynamically look up a property in the parent project errors have been fixed in #2034

Which release is this a part of?
