Maybe from

project.buildscript

?

I tried that but dependencies always shows up empty. I tried a bunch of of variations but not luck. Maybe I'm missing where they are contained in buildscript?

You usually get dependencies from configurations.

dependencies

is where you declare them.

I tried the following but the dependencies are always empty

register("bbb") {
        project.buildscript.configurations.forEach {
            println("Bellini: configurations")
            println(it.name)
            println("Bellini: deps")
            val deps = it.dependencies
//            deps.iterator().forEach {
//                println(it.name)
//            }
            it.allDependencies.iterator().forEach {
                println(it.name)
            }
        }
    }

Maybe because you do it at configuration time instead of execution time? (missing

doLast

)

Tried with doLast{} but still empty unfortunately.

Works fine here, even at configuration time

Thanks for helping here. Here is what my

buildSrc/build.gradle.kts

looks like:

plugins {
    `kotlin-dsl`
}

repositories {
    mavenLocal()
    mavenCentral()
    gradlePluginPortal()
}

dependencies {
    val versionKotlin = "1.5.10"        // help with version upgrades to make sure all version are aligned in this file
    implementation("org.jetbrains.kotlin:kotlin-allopen:$versionKotlin")

    implementation("com.ea.stuff:stuff-common:16.6.0-SNAPSHOT")    implementation("org.kie:kie-api:7.45.0.Final")
    implementation("org.drools:drools-compiler:7.45.0.Final")
    implementation("com.fasterxml.jackson.core:jackson-databind:2.13.1")
}

What I want to programmatically obtain is the version of the dependency

com.ea.stuff:stuff-common:16.6.0-SNAPSHOT

That is not a buildscript dependency, but a normal project dependency

Interesting... even though its the

buildSrc/build.gradle.kts

dependencies which has the plugins listed + and code used in the build script?

And where do you have the

bbb

task? And actually, what do you want to achieve?

I want to programmatically obtain is the version of the dependency

com.ea.stuff:stuff-common:16.6.0-SNAPSHOT

from the `buildSrc/build.gradle.kts`dependencies section. The

bbb

task is in a

stuff-conventions.gradle.kts

file with in the

buildSrc/src/main/kotlin/.../stuff-conventions.gradle.kts

Actually your problem is that you are using

buildSrc

and not an build. plugins / dependencies from an included build end up on the buildscript class path. (while you would still miss the dependency, because with your code you only get declared dependencies, no transitive ones which that one is from the viewpoint of the main build)

buildSrc

dependencies are in its own class loader that is a parent of the build script class loader. So those dependencies are not part of the build script configurations you are looking at.

I need to pass that version to a subprocess that is the gradle build starts but doesn't control. So rather than hard coding the version in two places, I want to programmatically grab it.

If you want to get the version at runtime, you probably need to get a class from that dependency and then get that classes codesource from its protection domain and then parse the version out of the JAR file name. Or if that dependeny provides its version via some Version class or properties file or manifest entry, then you might get it from there. Or you get the version not in your convention plugin, but actually during the buildSrc build and write it to some properties file your convention plugin then can read. Or you define the version in some variable (or probably better in a version catalog) and then use it to declare the dependency and also to generate said properties file with a

WriteProperties

task, or with a filter on

processResources

to fill in a blank in a properties file you create manually, that your convention plugin then can read at runtime.

Thanks. I tried adding it to gradle.properties and then reading the properties but the `buildsrc/build.gradle.kts`doesn't have access to that. Version catalog would be good to try assuming

buildsrc/build.gradle.kts

can access it (haven't tried). Appreciate the ideas, I'll work through some of these and see what works.

tried adding it to gradle.properties and then reading the properties but the `buildsrc/build.gradle.kts`doesn't have access to that

buildSrc/gradle.properties

I hope. Otherwise it would make little sense. Well, you could even read

gradle.properties

, but you then have to do it explicitly, using a

Properties

instance.
