I was also missing the dependency management plugin

[Czar]

I think you also need spring milestone repository in settings.gradle.kts for plugin resolution.

[bjonnh]

yes I have both of them

[bjonnh]

Now it seems that I broke the full kotlin…

[bjonnh]

Plugin [id: 'org.jetbrains.kotlin.jvm'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (plugin dependency must include a version number for this source)

[Czar]

Don't know why that error message, but not specifying version for kotlin plugin and specifying it for kotlin compiler plugins can lead to a conflict.
Those need to be in sync.
kotlin("jvm") version kotlinVersion

[bjonnh]

it is because it is a subproject

[bjonnh]

so it explicitly tells me not to put it

[bjonnh]

the main build.gradle.kts has a version

[bjonnh]

kotlin("jvm") version "1.3.30"

[bjonnh]

maybe my settings.gradle is overwriting some default plugin repository?

[Czar]

plugins block must be specified in the root project

[Czar]

in subprojects you just apply the plugins

[bjonnh]

pluginManagement {
repositories {
maven { url 'https://repo.spring.io/snapshot' }
maven { url 'https://repo.spring.io/milestone' }
gradlePluginPortal()
}
resolutionStrategy {
eachPlugin {
if (requested.id.id == 'org.springframework.boot') {
useModule("org.springframework.bootspring boot gradle plugin${requested.version}")
}
if (requested.id.id == "kotlin-multiplatform") {
useModule("org.jetbrains.kotlinkotlin gradle plugin${requested.version}")
}
if (requested.id.id == "kotlinx-serialization") {
useModule("org.jetbrains.kotlinkotlin serialization${requested.version}")
}
}
}
}

[bjonnh]

yep well it used to work before I changed to the 2.2.0

[bjonnh]

so clearly there is something I did that is not right

[Czar]

if you do not need a plugin in root project but only need it in sub, you define it with apply false in the root project and apply in subprojects where necessary

[bjonnh]

I'm talking about kotlin here…

[bjonnh]

If I don't have kotlin("jvm") in my sub project, I can't even get gradle to load my build.gradle.kts

[bjonnh]

so my hypothesis now is that I messed up something in the settings.gradle

[Czar]

your setup seems not correct to me, I've explained why, if you think I'm wrong, well good luck, I can't help 🙂

[bjonnh]

I don't understand what is wrong from what you said

[bjonnh]

I have :
plugins {
kotlin("jvm") version "1.3.30" apply false

}

in my base project

[bjonnh]

plugins {
kotlin("jvm")
}

in my sub projects.

[bjonnh]

(with additional plugins when needed

[bjonnh]

I removed stuff I had on the base project that I was not using so now I was able to "apply false" the plugin on the base project. And now it works

[bjonnh]

but I don't really get why

[bjonnh]

aren't they supposed to all use the same version?

[bjonnh]

it seems that removing the dokka tasks I had in the root project is what made it work (removing the apply false still make the project compile)

[Czar]

what version of gradle are you working on? apparently I lag behind a bit and plugins {} blocks are now supported in subprojects

[bjonnh]

latest included with the EAP intelliJ

[bjonnh]

4.10 maybe

[Czar]

that's important, check please, 4.10 is a dinosaur in terms of kotlin-dsl support

[Czar]

you can run ./gradlew -version

[bjonnh]

nevermind 5.2.1

[sdeleuze]

@bjonnh See https://github.com/spring-projects/spring-fu/blob/master/settings.gradle.kts

[sdeleuze]

I have various projects working with Boot 2.2.0.M2 and Gradle Kotlin DSL

[bjonnh]

yep looks like what I have

[bjonnh]

it works now

[Czar]

Ok, with that plugins are specified like this:
* in root project you specify all plugins which are to be used in the build, including all the plugins only subprojects will use
* those plugins that are not needed in the root project you specify with apply false
* in subprojects you specify the plugins that need to be applied without version
* buildscript with repository you have in the snippet in theory does nothing and can be removed.

[sdeleuze]

Oh ok

[sdeleuze]

What was missing?

[bjonnh]

I have no idea

[bjonnh]

just disabling dokka and its task in the root module seems to have made it

[bjonnh]

I didn't need it anyway there…

[sdeleuze]

Oh Dokka is another thing

[sdeleuze]

Let me find the link

[bjonnh]

@Czar Ok I'll move all my modules down at root then

[sdeleuze]

https://kotlinlang.slack.com/archives/C0F4UNJET/p1554474580016800?thread_ts=1553787379.004500&cid=C0F4UNJET

[sdeleuze]

Dokka 0.9.18 now requires additional repositories, see the thead for more details

[sdeleuze]

Not sure if that's related but worth to know

[sdeleuze]

I hope they will change that confusing requirement

[sdeleuze]

Gradle Kotlin DSL will be shortly supported on start.spring.io

[bjonnh]

I switched to orchid to generate my docs anyway so I don't use dokka directly anymore

[bjonnh]

it was an old remnant

[bjonnh]

Now that I moved spring boot plugins declaration to the root

[bjonnh]

it cannot find the right versions in the submodule…

[bjonnh]

I'll compare with your spring-fu

[bjonnh]

see what I missed

[bjonnh]

what is that: imports {
mavenBom("org.springframework.bootspring boot dependencies$bootVersion")
}

[sdeleuze]

Spring Fu is not a Boot app itself so that's not relevant for your use case

[bjonnh]

I'm completely lost now

[bjonnh]

I tried to move the plugins to the root project

[bjonnh]

but now it cannot find spring boot for the subprojects

[sdeleuze]

I think the easier way for others to help you is to share the structure of your project in a repo

[sdeleuze]

Otherwise it will be frustrating for everybody

[bjonnh]

https://www.bjonnh.net/share/project.zip

[bjonnh]

yeah I'll make a repo

[bjonnh]

https://github.com/bjonnh/spring-kotlin-subprojects

[bjonnh]

I moved the repositories back to the root project

[sdeleuze]

Thanks I will have a look later (currently away from keyboard)

[bjonnh]

thx

[bjonnh]

I'll continue working on it and updating the repo

[bjonnh]

ok I forgot to include the plugin in the subprojects

[bjonnh]

sorry for the disturbance…

[bjonnh]

I really have a hard time wrapping my head around gradle

[bjonnh]

and thanks both of you for the help!

[sdeleuze]

So that works now?

[bjonnh]

YES ! \o/
