DESCRIBE THE ISSUE IN DETAIL:

On a large project containing about ~100,000 resource files (xml), task :app:mergeReleaseResources uses ~4 times more memory when the isShrinkResources flag is enabled.

release {
  isMinifyEnabled = true
  isShrinkResources = true
}

Memory needs more than 40GB with high GC activity (see agp-is-shrink-resources-enabled.png in attachments).

release {
  isMinifyEnabled = true
  isShrinkResources = false
}

Memory needs less than 12GB (see agp-is-shrink-resources-disabled.png in attachments).

STEPS TO REPRODUCE:

1. Create a project with 100,000 resource-files stored in 2,000 gradle-subprojects and libraries;
2. Enable resource shrinking (isMinifyEnabled and isShrinkResources) for release build type;
3. Run ./gradlew :app:mergeReleaseResources gradle task.
