I ve defined Gradle Task in my root gradle scipt which works

Question

I ve defined Gradle Task in my root gradle scipt which works ```tasks register lt Exec gt skynet dependsOn bin nativeBinaries val bin = bin build bin native debugExecutable skynet kexe executable = sh args = listOf c bin ``` However I wanted to declare it like so ```val nativeBinaries by project bin tasks existing val nativeBinaries by tasks existing tasks register lt Exec gt skynet dependsOn nativeBinaries ``` But I can t seem to get a reference to it For context the nativeBinaries task exists in a kotlin native submodule called bin

Adam S · Answer

accessing the tasks and configurations of another subproject will usually lead to hard to diagnose problems

Adam S · Answer

if you zoom out on your problem can you explain what you re trying to achieve What does skynet kexe do Why are you trying to run it in a separate project

Charlie Tapping · Answer

I feel like we should be okay here because the root project isn t configuring any subprojects instead I m trying to declare a task which when executed triggers a subproject task

Charlie Tapping · Answer

So this is my project structure

Charlie Tapping · Answer

Root project skynet Root project skynet + Project bin Project lib

Charlie Tapping · Answer

bin is a kotlin native module

ephemient · Answer

depending on a task is not the same as depending on a task s outputs even within the same project

ephemient · Answer

don t do that use the proper way of exporting configurations artifacts

Charlie Tapping · Answer

I want to ensure that specifically the kotlin native task nativeBinaries is ran before i try to exec one of its outputs

Charlie Tapping · Answer

This is the full command

Charlie Tapping · Answer

```tasks register lt Exec gt skynet dependsOn bin nativeBinaries val bin = bin build bin native debugExecutable skynet kexe executable = sh args = listOf c bin ```

Charlie Tapping · Answer

So I would remove depends on and put what exactly

Adam S · Answer

there s a few different options so it depends

Adam S · Answer

if you want to depend on the compiled executable then maybe set up variant aware sharing or maybe use composite builds so you can run the task directly or set up your ` bin` project so it doesn t produce an executable it produces a library And then it the root project also set up Kotlin Native add a dependency on ` bin` and a custom K N target with an exec This stuff can be really complicated in Gradle but if you explained what s going on or what error you get or why the task needs to be run in a separate subproject then maybe there s a better way

Charlie Tapping · Answer

Thank you for the help

Charlie Tapping · Answer

The wider on all of this was that I simply wanted to run the native executable from gradle but gradle skipping that task I found that I could run it from cli though and then tried to call cli from gradle

it turns out the intelli j wizard doesnt generate the right config for apple silicon targets

ephemient · Answer

<https melix github io blog 2021 10 gradle quickie dependson html> dependsOn is the wrong thing regardless of whether it s in one project or not

ephemient · Answer

what you should do is to register every host binary type in the producer the ones that can t be built on the current platform will be automatically disabled

ephemient · Answer

then pick out the right one for local execution

ephemient · Answer

e g ```kotlin for target in listOf linuxX64 linuxArm64 macosArm64 macosX64 mingwX64 target binaries executable entryPoint ``` you can configure `executable runTaskProvider configure ` if you want to specify args or environment variables

ephemient · Answer

or if you really want to run it from another project export the binaries ```kotlin targets withType lt KotlinNativeTarget gt binaries matching it outputKind == NativeOutputKind EXECUTABLE all artifacts add configurations create $ this withType name $ name capitalized isCanBeConsumed = true isCanBeResolved = false attributes attribute KotlinPlatformType attribute KotlinPlatformType native attribute KotlinNativeTarget konanTargetAttribute konanTarget name attribute KotlinNativeTarget kotlinNativeBuildTypeAttribute buildType name attribute Usage USAGE ATTRIBUTE objects named native binary name this linkTaskProvider ``` and consume the specific one ```val hostSkynetBinary by configurations creating isCanBeConsumed = false isCanBeResolved = true attributes attribute KotlinPlatformType attribute KotlinPlatformType native attribute KotlinNativeTarget konanTargetAttribute HostManager host name attribute KotlinNativeTarget kotlinNativeBuildTypeAttribute DEBUG attribute Usage USAGE ATTRIBUTE objects named native binary dependencies hostSkynetBinary project bin tasks register skynet Exec class inputs files hostSkynetBinary commandLine bin sh c argumentProviders add listOf $ hostSkynetBinary singleFile kexe ```

Wow thats super useful to know thank you there is actually a pair of tasks for running the binaries generated `runDebugExecutableNative` and `runReleaseExecutableNative` It just I couldn t get these working at first because of the wizard generated config which targeted x86 binaries
