I have some helper functions inside

*.kt

files in my

build-logic

project that I use in convention plugins. It’s something like

fun Project.doSomething()

and I want to use them in my

app/build.gradle.kts

as well. Is it possible to achieve somehow?

Gradle's

buildSrc

directory might be what you're looking for. Basically, it's for any code you want to add to the build itself. You can use it to define little helper functions up to full fledged project specific gradle plugins: https://docs.gradle.org/current/userguide/organizing_gradle_projects.html#sec:build_sources

Yes, it's possible. When using buildSrc any util functions will be available in all scripts, even if you don't apply a plugin in the build scripts. If you use an included build instead of buildSrc then you need to apply a plugin (even if it's an noop one!) to access the util functions. I normally create a convention plugin like

build-logic/src/main/kotlin/my-cool-project-base.gradle.kts

that contains conventions for all subprojects, and apply it to all subprojects.

anything that brings it into the buildscript classpath will work - you can even create an empty plugin in

build-logic

and apply it, or pull in an existing plugin (possibly with

apply false

), or use the old

buildscript.dependencies.classpath
