Overview

Reconciles the gradle-wrapper.properties file after Gradle's wrapper task has regenerated it from hardcoded defaults (see https://github.com/gradle/gradle/issues/36172).

The reconciliation policy is deliberately conservative: the user's original file is the source of truth for everything (comments, ordering, custom keys, networkTimeout, retries, retryBackOffMs, validateDistributionUrl, distributionBase/Path, store paths, ...). Only the keys that legitimately change for a version bump are taken from the regenerated file.

MANAGED_KEYS =

Keys whose value is owned by the update itself and therefore taken from the regenerated file. Everything not listed here is preserved verbatim from the user's original file.
