Reduce performance overhead

[liutikas]

As part of writing up a post on expected Gradle configuration performance I found that com.diffplug.spotless causes 17 second regression in configuration performance Androidify Gradle project.

Simply removing com.diffplug.spotless from root build.gradle.kts and rerunning the Gradle profiler we get configuration time from 26s to 9s.

• Great writeup! Looks like this pr can help, i'll try to get it merged and released ASAP Use Task Providers for task initialization #2719

The great PR mentioned above from @simonlebras has been merged and released in spotless-plugin-gradle 8.1.0. Hopefully it improves the performance issue you identified.

Spotless removed (build scan)

Effectively no improvement between 8.0.0 and 8.1.0

Spotless 8.0.0 (build scan)

Spotless 8.1.0 (build scan)

All the added time is effectively due to going from 3.8s to 20.5s for configuration cache store.

Cache size itself doesn't grow a lot, it goes from 12.8 MiB to 12.9 MiB. Something in the spotless tasks is causing Gradle to enter an extremely slow path in CC serialization.

A few experiments.

1. Apply the plugin but do not set anything in the extension

10.374s almost the same performance as without plugin being applied.

2. Apply the plugin but keep the xml formatting setup

15.415s
