Can someone help me understand why two Gradle daemons are being spawned when I run for i.e. “Clean Project” in Android Studio in a project with build-tools as includedBuild?
I’ve configured the AS (Otter 2025.2.1) to use the Gradle wrapper (version 8.14.3), but for some reason, another daemon starts up using the 9.0-milestone-1 distribution.

[gildor]

maybe another project which has different Gradle wrapper?

[gildor]

does includedBuild has the same version of Gradle?

[Nick Kleban]

Only one project opened in Android Studio. included-build is similarly structured as build-logic in nowinandroid it has no own wrapper and only gradle related settings are in build-logic/gradle.properties

org.gradle.caching=true
org.gradle.parallel=true
org.gradle.daemon=true

kotlin.compiler.runViaBuildToolsApi=true
kotlin.compiler.execution.strategy=in-process

For example, I’ve run three scenarios, and before each one, I manually deleted
build-logic/.gradle/
build-logic/build/

1. In terminal ./gradlew clean
2. In AS clean in gradle tab
3. In AS menu Build -> Clean Project
Only 3rd one resulted 9.0-milestone-1 appearing in .gradle folder

build-logic/.gradle/8.14.3
build-logic/.gradle/9.0-milestone-1

and daemon with the same version was spawned.

1. In AS menu Build -> Clean Project

You should never do this

[gildor]

it probably explains it

[gildor]

but in general, do not use Build menu in AS, it always had very nasty behaviour and not really recommended

[Nick Kleban]

Any motivation behind this?

In AS menu Build -> Clean Project
You should never do this

Sometimes I need to clean build-logic too and it’s the most convenient way to do it as simple ./gradlew clean in root project doesn’t clean build-logic/build

[gildor]

Any motivation behind this?

Because it does it without Gradle and this what you get I believe, it uses standalone gradle to run tasks

It was always really bad with Build -> Rebuild, when it run a lot of unnecessary tasks which slowdown you a lot

[gildor]

so in general, you can just do included buildclean or just rm -df whateverYouNeed and add it to run menu maybe

[gildor]

are you sure that you have "clean" task on build-logic?

[Nick Kleban]

Too be honest it sound like some kind of a bug) At least this daemon don’t consume too much of resources - xmx512m I believe. Thank you for the explanation

are you sure that you have “clean” task on build-logic?

It has clean task, it’s just not being called when I’m running clean in the root project

------------------------------------------------------------
Tasks runnable from project ':build-logic'
------------------------------------------------------------

Build tasks
-----------
assemble - Assembles the outputs of this project.
build - Assembles and tests this project.
...
clean - Deletes the build directory.
...
testClasses - Assembles test classes.

Probably by strict definition, it's not necessary a bug, more like unclear semantics. If build-logic doesn't have it's own wrapper, studio probably uses built in gradle

I didn't check if it actually true, but it matches with other issues that are known with Build menu and why it's not really recommended to use

[gildor]

My advice just avoid it, and do clean with gradle with multiple tasks like clean :build-logic:clean you can create a run item if you want to do it from AS

But in general you shouldn't use clean so often until you test some performance or debugging some problem

[Colton Idle]

i wonder if implementing gradle doctor would fix this. gradle doctor would check if you're using separate jdks inside of studio vs on cmd line and therefore (IIRC) itll spawn a separate gradle daemon.

it was written by someone that used to work at gradle https://github.com/runningcode/gradle-doctor

[gildor]

@Colton Idle but JDKs are not different, it's just external Gradle used to run build without gradle wrapper
Not quite sure how gradle doctor can detect it

[gildor]

How is it even related?

[Meet]

It desktop app analysis Android project and storage

[gildor]

so how it can help solving this issue?

[gildor]

You as author could demonstrate maybe that it would somehow help, otherwise it looks more like unrelated spam than an actual help

[gildor]

I'm checking features and none of them look related to this

[Meet]

Ok sorry I feel it related project because in my project analysis project and gradle wrapper. I am not spam it ok I delete message thank you

[gildor]

Yes, if you meant to check your setup, it also not very relevant, because you don't have included build with build logic as OPs project

[Meet]

Ok I understand sorry my mistake
