Hi @copitz, thx for letting me know. I didn't know about this alternative approach! Looks promising, I'll test it next time I need this. 👍

Hi, @matthiasbalke what do you think about this one: https://stackoverflow.com/a/47107135/2906505 ? Any pitfalls?

Hi, @dhasilin in my opinion gradle dependencies does not download all dependencies for all subprojects, but I'm not sure. Maybe I didn't know about that task back in the days.

If you're curious just rename your ~/.gradle directory then use gradle dependencies. Afterwards rename it again and use my script. This way you can compare the outcome of the two methods by comparing the generated ~/.gradle directories.

FYI: a Kotlin version of the code snippet of @copitz:

tasks.register<Task>(name = "resolveDependencies") {
    group = "Build Setup"
    description = "Resolve and prefetch dependencies"
    doLast {
        rootProject.allprojects.forEach {
            it.buildscript.configurations.filter(Configuration::isCanBeResolved).forEach { it.resolve() }
            it.configurations.filter(Configuration::isCanBeResolved).forEach { it.resolve() }
        }
    }
}

@dirkbolte thanks for sharing this! 👍
