Hi! I'm new to Kotlin. Does Kotlin support having more than one src folder?

[Ryan]

yes

[Ryan]

but thats more your build system

[Joakim Tengstrand]

I come from Clojure and in Clojure, multiple src folders are supported both in the build tooling and in the IDE. Is there any IDE support for multiple src folders in Kotlin?

[Ryan]

sourceSets["main"].java.srcDir("$generatedJavaSourcesPath/kapt/main")

i’m using kotlin gradle dsl

[Joakim Tengstrand]

Thanks

[Joakim Tengstrand]

Can you please guide me to a good example project that uses gradle dsl?

[Joakim Tengstrand]

Found one here: https://github.com/JetBrains/kotlin/blob/master/build.gradle.kts

[Ryan]

you can download gradle quickstart and create a new kotlin project.

[Joakim Tengstrand]

But it is huge.

[Joakim Tengstrand]

Ok, will try that.

[Joakim Tengstrand]

I can create a simple app from IDEA that creates a .iml project file (https://kotlinlang.org/docs/tutorials/jvm-get-started.html) but I haven't figured out how to create a corresponding gradle dsl build file.

[Joakim Tengstrand]

Thanks! Now it will be easier to dig in.

i guess it can be confusing using the gradle kotlin dsl to build a kotlin project lol

[Joakim Tengstrand]

I expected to find something like "Create Gradle DSL project" in IDEA.

[Joakim Tengstrand]

I installed gradle + pointed out its root in the settings. I also created the file build.gradle.kts at the project root that looks like this. When I enter the module settings I can see that IDEA doesn't understand where my src folders live, and therefore I can't execute a main function under on of the two src-folders:

plugins {
    kotlin("jvm") version "1.3.72"
}

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath(kotlin("gradle-plugin", version = "1.3.72"))
    }
}

sourceSets.main {
    java.srcDirs("components/logger/src",
                 "components/user/src")
}

[Joakim Tengstrand]

I get the error 'gradle-wrapper.properties' not found.

[Joakim Tengstrand]

After executing "gradle wrapper" I don't have that error message, but I can still not execute my function (which worked when I had my src folder on the root).
