Unable to resolve dependencies

[snowe2010]

When using

    <dependency>
      <groupId>ai.hypergraph</groupId>
      <artifactId>kotlingrad</artifactId>
      <version>0.4.7</version>
    </dependency>

I'm unable to resolve any ai types.

If I switch to

    <dependency>
      <groupId>ai.hypergraph</groupId>
      <artifactId>kotlingrad-jvm</artifactId>
      <version>0.4.7</version>
    </dependency>

instead, I get failures to resolve kotlin-bom

Unresolved dependency: 'org.jetbrains.kotlin:kotlin-bom:jar:1.6.10'

Currently it seems impossible to use this project with the current pom setup. Do you have an example of an external project using kotlingrad where this works?

[breandan]

Hi @snowe2010, thank you for checking out Kotlin∇! It should be possible to use Maven, however I have not rigorously tested this setup so there may be errors. Can you try cloning this project and run ./gradlew run on your local machine?

[snowe2010]

Sure thing. After cloning that project and building (I set asdf to use a graalvm version of java17, but should still work the same) I get this error:

❯ asdf local java graalvm-22.0.0.2+java17

Since it looks like you're trying to explicitly use java 15 I set asdf to use openjdk-15.0.2 which resulted in the same errors.

[snowe2010]

Ok, seeing something really weird. I wipe your artifact from my .m2 repo and then the gradle build works fine.

As soon as I try to build using maven it fails. I believe this might be related to our nexus repository. I'll get back to you in a bit.

[snowe2010]

@breandan it looks like the issue is with the maven artifact, though not sure why. It fails even if I use the artifact from maven central, so it's not an issue with our nexus repo. Here is an example app: kotlingrad-maven.zip

[snowe2010]

from a cursory glance over the code it looks like you're not actually adding the jar to the publication, though I'm not sure how this is working with gradle then. I suspect it's due to gradle's metadata capabilities.

[breandan]

You're probably right, it looks like something to do with how we're publishing our build artifact. I used to be a fan of Gradle, but after nearly a decade of fighting with it (e.g., #6, #26 in just this project) I've come to accept the fact that I do not understand Gradle and never will. Typically Gradle can resolve Maven dependencies written as:

dependencies { implementation("G:A:V") }

But the fact that Maven cannot resolve Gradle artifacts published on Maven Central using the syntax:

<dependency><groupId>G</groupId><artifactId>A</artifactId><version>V</version></dependency>

indicates to me that something is definitely wrong with (1) either our Maven publication or (2) Gradle's dependency resolution mechanism or (3) possibly both. Thank you for reporting this issue!

[snowe2010]

Yes, Gradle can be quite difficult to use, though I do like it more than Maven for most use cases. Looking at your build.gradle though, it is quite complex, so I would expect some issues with that. I don't completely understand everything you're doing, especially with the git submodules and this shipshape library. I think most of the issues here are coming from your use of kotlin multiplatform. Have you tried following along with how a project like kotest does multiplatform?
