10/25/2023, 5:11 PMI want to clear build cache, config cache, and project-level cache between each build. So I added to my scenario file:
Jason Atwood
10/25/2023, 5:11 PM Copy code
clear-configuration-cache-state-before = BUILD
clear-project-cache-before = BUILD
clear-build-cache-before = BUILDJason Atwood
10/25/2023, 5:29 PMBut when I run gradle-profiler I'm getting an error about setting BUILD....

@Override
public boolean allowsCleanupBetweenBuilds() {
// Warm daemons keep caches open and thus they cannot be removed
return !isReuseDaemon();
}Jason Atwood
10/25/2023, 5:32 PMhow can I clear caches between builds and reuse the Gradle Daemon?

10/25/2023, 5:53 PMI believe you can't. I don't understand what motivated this limitation. There's an open issue about improving the error message, but not one about lifting it.

10/25/2023, 7:41 PMDaemon keeps caches open (as comment indicates 🙂), which basically means it holds file locks for caches open. It might even keep some things in the memory. So if you try to clean cache: either clean will fail or retrieving from cache could fail or return some stale data.

10/26/2023, 4:44 PMI want to benchmark by builds without using any of the project-cache or build cache. Presumably I want to clear these before every iteration. But I do want to capture the benefit of re-using the daemon.
Jason Atwood
10/26/2023, 4:47 PMI realized that what I really need is to use --rerun-task and --no-configuration-cache, instead of using the profiler flags
Copy code
package-universal-apk {
title = "Package universal apk"
tasks = ["app:packageInternalDebugUniversalApk"]
warm-ups = 2
iterations = 5
cleanup-tasks = ["clean"] # run before each build
gradle-args = ["--rerun-tasks", "--no-configuration-cache"]
}g

10/26/2023, 4:50 PMFor that intent, yes. Also, since you're using
--rerun-tasksclean4 Views
