I have issues in :scripts when importing something from the namespace present in :services

[bjonnh]

If I remove the springboot dependencies it find it perfectly

[bjonnh]

looks similar to : https://discuss.kotlinlang.org/t/spring-boot-gradle-multi-module-compilation-error/8130

[bjonnh]

Except that adding the dependencyManagement part doesn't seem to solve anything. Also intelliJ finds the import properly, it is really gradle that complains

[bjonnh]

ok moving the models to a library that is not in a spring boot application solve the issue

[bjonnh]

if anybody as an explanation of why, I would be happy to know

[snowe]

Since you are using spring boot 2, I would instead recommend using gradle's platform configuration, which allows you to import boms like maven.

[snowe]

you didn't commit your gradle directory, so i'm not sure what gradle version you are using.

[snowe]

https://docs.gradle.org/current/userguide/java_platform_plugin.html#sec:java_platform_consumption

[snowe]

https://gradle.org/whats-new/gradle-5/#bom-support

[snowe]

you can use it in gradle 4.6, but you need a special setting.

[bjonnh]

I'm using 5.2.1

[snowe]

then I would suggest using implementation(platform(..))

[bjonnh]

ok that seem to work

[snowe]

👍🏽

[bjonnh]

well it was working before too

[bjonnh]

but at least it didn't seem to break anything 😛

[snowe]

yes, well they work the same way. but now you don't need that dependencyManagement plugin or block

[snowe]

😉

[bjonnh]

oh neat

[bjonnh]

hmm if I remove it it fails to find the packages

[bjonnh]

should I put something special in the library?

[snowe]

what's the error?

[bjonnh]

unable to resolve <name of the spring package>

[bjonnh]

that's in :scripts that is importing models from :api-library

[snowe]

does it include the version? can you provide the project? or build.gradle.kts.

[bjonnh]

oh wait

[bjonnh]

let me update the repo

[snowe]

yeah ha.

[snowe]

I was wondering 😂

[bjonnh]

ok

[bjonnh]

now that's the repo I used and made that error

[bjonnh]

(you will realize that I have no idea what I'm doing…)

[snowe]

you are still applying the plugin https://github.com/bjonnh/gradle-kotlin-spring-debug/blob/master/api-library/build.gradle.kts#L3

[bjonnh]

oh

[snowe]

you don't need to use apply if you use the plugins block https://github.com/bjonnh/gradle-kotlin-spring-debug/blob/master/api-library/build.gradle.kts#L8-L10

[bjonnh]

\o/

[bjonnh]

beautiful

[snowe]

you don't need this if you are using the platform declaration https://github.com/bjonnh/gradle-kotlin-spring-debug/blob/master/api-library/build.gradle.kts#L14-L16

[snowe]

don't need this. https://github.com/bjonnh/gradle-kotlin-spring-debug/blob/master/build.gradle.kts#L13

[bjonnh]

I like that… the less lines I have in those files the better I feel

[snowe]

I don't see where you are using platform

[bjonnh]

in scripts

[snowe]

sorry, it seems you misunderstood.

[bjonnh]

likely

[snowe]

platform is a replacement for dependencyManagement. Do you know what a BOM is?

[bjonnh]

nope

[bjonnh]

so I should remove that dependencyManagement also from api-library?

[snowe]

BOM stands for Bill Of Materials. It is essentially a parent pom that declares what versions of libraries should be used. Are you familiar with maven?

[bjonnh]

a tiny bit

[bjonnh]

enough to break things

[bjonnh]

should I remove that dependency management completely

[snowe]

haha. ok, so if you have a parent pom, you can declare a bunch of dependencies in a <dependencyManagement> block in the parent pom. and then anywhere you use that parent pom (other microservices or libraries or whatever), you will be able to declare a dependency without declaring a version.

[snowe]

I will send a pr.

[snowe]

give me a sec.

[bjonnh]

yes that's exactly what I'm trying to do

[bjonnh]

so I don't have to give the spring versions in each submodule

[snowe]

what version of gradle are you using?

[snowe]

oh sorry 5.2.1

[bjonnh]

now that I removed the dependencymanagement everywhere, no submodule finds the versions for spring modules

[bjonnh]

at least they all agree on that

[snowe]

yep, give me just a minute.

[bjonnh]

sure

[snowe]

hmm. this is kinda a mess 😅

[snowe]

it's taking much longer than normal for me to fix it.

[bjonnh]

yes that's the feeling I have everytime I touch gradle. And looking at other people repositories, they all have completely different ways of handling things

[bjonnh]

so it is hard to find a reference implementation for anything

[snowe]

do you want me to make the pr the way I would do it?

[snowe]

or follow your style and try and fix it your way?

[bjonnh]

absolutely

[bjonnh]

I have no style

[bjonnh]

you can burn anything you want

[snowe]

😂

[bjonnh]

I'm really lego-ing things until they work

[snowe]

https://github.com/bjonnh/gradle-kotlin-spring-debug/pull/1

[snowe]

so, if you look at the root build.gradle.kts file you'll now see the BOM implementation in the allprojects block.

[snowe]

this applies the BOM to all projects, allowing the versions to resolve.

[snowe]

I completely removed the spring dependency management plugin.

[bjonnh]

Thanks

[bjonnh]

never seen that nebula.kotlin

[snowe]

it just adds a BOM for kotlin essentially. makes it so you don't have to track versions through the rest of the project.

[bjonnh]

cool

[bjonnh]

ok I'm done integrating the changes in my real app

[bjonnh]

lets see if it blows up 😄

[snowe]

😂

[bjonnh]

hey

[bjonnh]

it also removed all the duplicate tasks I had in gradle

[bjonnh]

🎆 Thanks @snowe

[snowe]

awesome! you're welcome! some of those things just come with time. I've only been using gradle for a few months, but it's been getting much easier.

[bjonnh]

yep I'm learning a lot of stuff at the same time, and programming is not my main job so…

[snowe]

oh!

[snowe]

wow. well good job then! haha

[bjonnh]

[bjonnh]

that's the kind of stuff I do with kotlin ^

[snowe]

oh nice!
