Configuration cache support

See

Invocation of 'Task.project' by task ':bufFormatApply' at execution time is unsupported.

Check https://docs.gradle.org/current/userguide/configuration_cache.html for details.

It's not clear to me what this issue is. Is this a bug causing Gradle to fail? Is this a feature request for an invocation or configuration style that does not currently work?

[davireis]

It is a feature request. Configuration cache is a new feature in gradle that speeds up the configuration phase of the build by caching it. However, it requires plugin authors to restrict some actions, like accessing Task.project at execution time.

The lack of configuration cache does not cause gradle to fail, but it causes it to become (significanly) slower, because even if a single plugin fails to adhere to the rules, the whole cache is invalidated (alternatively, you can mark to ignore the failure to adhere of a plugin).

This is now a blocker for us, so I'll try to provide a fix PR. I have a PoC ready, let's see if I'll be able to make a nice PR and fix all corner cases.
