Hi. How can I write the following in

build.gradle.kts

Copy code

sourceSets {
    main {
        java { srcDir "./src" }
        kotlin { srcDir "./src" }
        resources { srcDir "./resources" }
    }
    test {
        kotlin { srcDir "./test" }
    }
}

In Groovy

build.gradle

I typically define (reusable) ext properties in my build scripts like:

Copy code

buildscript {
    ext {
        javaVersion                     = "1.8"
        kotlinVersion                   = "1.2.0"
        springBootVesion                = "2.0.0.M7"
        querydslVersion                 = "4.1.4"
        querydslGradlePluginVersion     = "1.0.8"
    }

And the I can refer to these properties when declaring plugins and dependencies. What is the proper way to this within Kotlin DSL?

there’s a known issue about IntelliJ not using the right version of the Gradle wrapper with

buildSrc

Has anyone tried the ivypot gradle plugin? https://github.com/ysb33r/ivypot-gradle-plugin I am getting the following error when I try and sync repos:

module not found: org.jetbrains.kotlin#kotlin-stdlib;${kotlin.version}

Hi guys, quick question - is there anything like

gradle.ext

that I can use to make values from settings.gradle.kts available to build.gradle.kts?

nope, none of it works.

I can do it this reasonably terrible way, of course, by insert this into

settings.gradle.kts

Copy code

operator fun Settings.get(key: String): String {
            return javaClass.getMethod("getProperty", String::class.java).invoke(this, key) as String
        }

and then referring to

settings["property"]

for example

Hey guys, how can I access / set

archivesBaseName

? I saw some scripts using

base { archivesBaseName = ".." }

but can’t get that work.. always get the following compile error - even though it get’s recognized and resolved in the editor in IntelliJ

Copy code

Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:
public val PluginDependenciesSpec.base: PluginDependencySpec defined in org.gradle.kotlin.dsl

@kartikpatodi im not following - what are you trying to do?

classpath("javax.xml.bind:jaxb-api:2.3.0")

this in my buildscript dependencies worked

Copy code

checkstyle {
    toolVersion = "8.4"
    sourceSets.forEach( { println(it) })
    sourceSets.removeIf( { it.name == "test" })
}

I said I was done, but is there any chance that this is a bug in the dsl? using groovy I could just pass a string, and that could be null as long as I wasn't trying to publish

Copy code

publishing {
    repositories {
        maven {
            url = uri(System.getenv("JRS_S3_URI") ?: "" )

@gildor can't figure out how to upload a file in a thread apparently

xenoterracide

12/21/2017, 9:08 AM

well the difference in groovy I think is that groovy somehow is evaluating it later, somehow it's much more eagerly evaluated by kotlin instead of only being evaluated when I do a

gradle publish

btw, I noticed the README.md says you can't use kotlin for gradle.settings, but the sample's all do

I mean I understand the warning, I guess I don't understand why there's a duplicate

12/21/2017, 11:50 AM

well I'd love to leave the if statements out

Hi all 🙂 Has anyone had success with setting up Travis CI (GitHub) with Gradle (Kotlin DSL) for OpenJDK9? I can't find any example repo.. Thanks!

araqnid

12/21/2017, 2:38 PM

it just works as normal if you have

language: java

set in the control file and a Gradle wrapper to specify a recent Gradle version (e.g. https://travis-ci.org/araqnid/fuel-log runs on 8 and 9)

or is there a cleaner approach with kotlin dsl?

12/22/2017, 2:35 PM

can someone explain

Copy code

System.getenv("JRS_S3_URI")?.let {
    val sourcesJar by tasks.creating(Jar::class) {
        classifier = "sources"
        from(java.sourceSets["main"].allSource)
    }

    publishing {
        repositories {
            maven {
                url = uri(it)
                credentials(AwsCredentials::class.java) {
                    accessKey = System.getenv("JRS_ACCESSKEYID")
                    secretKey = System.getenv("JRS_SECRETACCESSKEY")
                }
            }
        }
        (publications) {
            "mavenJava"(MavenPublication::class) {
                from(components["java"])
                artifact(sourcesJar)
            }
        }
    }
}

from the gradle version? I don't get why it's

AwsCredentials::class.java

or even what the java is at all, or why publications is

Copy code

(publications) {
"mavenJava"(MavenPublication::class) {

like literally If I hadn't copied it, I would never have figured it out from what I had

and on a non kotlin specific note, anyone know if there's a good way to compare a before and after classpath with gradle. had a problem that turned out to be the classpath, and I figured out which dependency 'caused the issue, but since that dep is basically exporting transitives, and I'm not sure which might have been missing...

what's the equivalent of this in kotlin

Copy code

configurations { driver }

dependencies { driver 'org.xerial:sqlite-jdbc:3.7.2' }`
