Just select "Build" -> "Rebuild project"

You can get all of this in first comment

This is a very interesting bug but I would file it against Gradle directly if you have done so already. this seems to be an issue with the Gradle's execution engine.

I think issue in gradle tasks orders when rebuild project (Log for same project with different studio versions) :

// Stable studio version:
Executing tasks: [:android-pdf-viewer:clean, :benchmark_mobile:clean, :benchmark_wear:clean, :liba:clean, :mobile:clean, :wear:clean, :android-pdf-viewer:assembleDebug, :benchmark_mobile:assembleBenchmark, :mobile:assembleProdDebug, :benchmark_wear:assembleBenchmark, :wear:assembleDebug, :liba:assembleDebug]

// Canary studio version (clean modules after build):
Executing tasks: [:android-pdf-viewer:clean, :android-pdf-viewer:assembleDebug, :benchmark_mobile:clean, :benchmark_mobile:assembleBenchmark, :mobile:assembleProdDebug, :benchmark_wear:clean, :benchmark_wear:assembleBenchmark, :wear:assembleDebug, :liba:clean, :liba:assembleDebug, :mobile:clean, :wear:clean]

Still broken on canary 14

I was on Canary 13 with Gradle 8.2 and Android gradle plugin 8.0.2

I upgraded to Canary 14 and kept Gradle 8.2 and Android gradle plugin 8.0.2

So the only change was Canary 13 -> 14.

Seems to be gradle independent?

Edit: I'm on the Canaries because the stable version is broken; see issue #285577375

Edit2: and just to confirm, yes, building from the command-line WORKS.... it's ONLY failing in Canary 14.

Just updated to Canary 15, with Gradle 8.2 and Android gradle plugin 8.0.2 => same problem.

Updated to Gradle 8.2.1 ==> same problem; building from the command-line WORKS.... it's ONLY failing in Canary 14 and 15.

Re #12:

If you run :android-pdf-viewer:clean :android-pdf-viewer:assembleDebug :benchmark_mobile:clean :benchmark_mobile:assembleBenchmark :mobile:assembleProdDebug :benchmark_wear:clean :benchmark_wear:assembleBenchmark :wear:assembleDebug :liba:clean :liba:assembleDebug :mobile:clean :wear:clean from the command line, do you hit the same issue?

I have reached out to Gradle to reopen the issue on their end, but we'll also try to see if there is something we can do on our end.

Just to be absolutely clear:

using the graddle binaries and configuration from the IDE and building from the command-line from the terminal inside the IDE ...WORKS.... it's ONLY failing when doing a build from the menus/buttons in Canary 14 and 15.

Also, for me at least, it only seems to affect my multi-module projects. Single module projects build fine.

Re #14, #15:

Android Studio builds a list of tasks and asks Gradle to execute it. The order of tasks in the request should not matter, it is responsibility of Gradle task execution machinery to determine the order in which it can execute them. Now, because there is a bug in Gradle (https://github.com/gradle/gradle/issues/21325) it seems like the change in order of tasks is causing problems.

Can someone please upload a sample project that reproduces the problem so that I can pass it to Gradle?

In the meantime, we can work around this issue in Android Studio putting the clean tasks first in the list.

Answering questions from #14:

Why if i do rebuild i got clean project instead? How should it work?

Rebuild project means that we want to remove the old outputs and request a new build, and running clean tasks is a way to accomplish that.

Are you sure that the problem is not in building a list of tasks?

As mentioned above, the order of tasks seems to trigger a bug in Gradle. The task list itself is correct.

You can get any project. Just now i checked on https://github.com/android/nowinandroid Procedure:

1. Clone project
2. Import to Android Studio Canary 15
3. Click Build -> Rebuild project Result same.

AS generated next list of tasks (clean/assemble/clean/assemble...):

:app:clean :app:assembleDemoDebug :app-nia-catalog:clean :app-nia-catalog:assembleDebug :benchmarks:clean :benchmarks:assembleDemoBenchmark :lint:clean :lint:assemble :ui-test-hilt-manifest:clean :ui-test-hilt-manifest:assembleDemoDebug :core:analytics:clean :core:analytics:assembleDemoDebug :core:common:clean :core:common:assembleDemoDebug :core:data:clean :core:data:assembleDemoDebug :core:data-test:clean :core:data-test:assembleDemoDebug :core:database:clean :core:database:assembleDemoDebug :core:datastore:clean :core:datastore:assembleDemoDebug :core:datastore-test:clean :core:datastore-test:assembleDemoDebug :core:designsystem:clean :core:designsystem:assembleDemoDebug :core:domain:clean :core:domain:assembleDemoDebug :core:model:clean :core:model:assemble :core:network:clean :core:network:assembleDemoDebug :core:notifications:clean :core:notifications:assembleDemoDebug :core:testing:clean :core:testing:assembleDemoDebug :core:ui:clean :core:ui:assembleDemoDebug :feature:bookmarks:clean :feature:bookmarks:assembleDemoDebug :feature:foryou:clean :feature:foryou:assembleDemoDebug :feature:interests:clean :feature:interests:assembleDemoDebug :feature:search:clean :feature:search:assembleDemoDebug :feature:settings:clean :feature:settings:assembleDemoDebug :feature:topic:clean :feature:topic:assembleDemoDebug :sync:sync-test:clean :sync:sync-test:assembleDemoDebug :sync:work:clean :sync:work:assembleDemoDebug :build-logic:convention:clean :build-logic:convention:assemble

If execute in began "clean" tasks and next "assemble" tasks build will correct (This behavior has changed since version 11):

:app:clean :app-nia-catalog:clean :benchmarks:clean :lint:clean :ui-test-hilt-manifest:clean :core:analytics:clean :core:common:clean :core:data:clean :core:data-test:clean :core:database:clean :core:datastore:clean :core:datastore-test:clean :core:designsystem:clean :core:domain:clean :core:model:clean :core:network:clean :core:notifications:clean :core:testing:clean :core:ui:clean :feature:bookmarks:clean :feature:foryou:clean :feature:interests:clean :feature:search:clean :feature:settings:clean :feature:topic:clean :sync:sync-test:clean :sync:work:clean :build-logic:convention:clean :app:assembleDemoDebug :app-nia-catalog:assembleDebug :benchmarks:assembleDemoBenchmark :lint:assemble :ui-test-hilt-manifest:assembleDemoDebug :core:analytics:assembleDemoDebug :core:common:assembleDemoDebug :core:data:assembleDemoDebug :core:data-test:assembleDemoDebug :core:database:assembleDemoDebug :core:datastore:assembleDemoDebug :core:datastore-test:assembleDemoDebug :core:designsystem:assembleDemoDebug :core:domain:assembleDemoDebug :core:model:assemble :core:network:assembleDemoDebug :core:notifications:assembleDemoDebug :core:testing:assembleDemoDebug :core:ui:assembleDemoDebug :feature:bookmarks:assembleDemoDebug :feature:foryou:assembleDemoDebug :feature:interests:assembleDemoDebug :feature:search:assembleDemoDebug :feature:settings:assembleDemoDebug :feature:topic:assembleDemoDebug :sync:sync-test:assembleDemoDebug :sync:work:assembleDemoDebug :build-logic:convention:assemble

Also "should not matter" please check.

I was able to reproduce with https://github.com/android/nowinandroid and I have passed this information to Gradle.

The part of task ordering that should not matter is about whether requested tasks are specified as ":foo:clean :foo:assemble :bar:clean :bar:assemble" or ":foo:clean :bar:clean :foo:assemble :bar:assemble". Obviously, if you run ":foo:assemble :foo:clean" that will 1st assemble :foo and then delete its output. Hopefully that clarifies things.

Actually not I can see in #13 that :mobile:assembleProdDebug is before :mobile:clean in the list, which is definitely off. I'm unable to repro that specific issue in NowInAndroid (clean is always before assemble task), but putting clean tasks first in the list will address that issue as well.

Looking again at https://github.com/gradle/gradle/issues/21325, there is a comment by a gradle engineer requesting to open a new issue but nothing else.

can you please provide a link to the gradle issue you presumably opened ?

There is a new comment because I pinged them about this issue.

I did not provide a link to the issue because I did not file one. It is always better if the filed issue comes directly from impacted users, so please do file one and comment on the existing Gradle issue with the link to a new one.

Fixed in studio-main in https://cs.android.com/android-studio/platform/tools/adt/idea/+/48279ae66574a2f0d13f8585bb1d3b6322cb9a7e, still needs to be cherry-picked for H so keeping this open.

FYI - studio-hedgehog-dev branch is ready for check ins, so feel free to cp!

Merged in studio-hedgehog-dev as ag/I6b77300ed47ddebef55f06a433bebd654897aced.

still a problem in Canary 16

This will be fixed in H Beta1, note that H Canary 16 still has this issue.

ah - thank you for letting us know

Iguana Cannary 14 still has this issue

Re #29: Can you please file a new issue with a sample project and steps to reproduce the bug?

Sorry for the late reply!
