Error resolving Kotlin dependencies when running smithy-rs JAR from mavenCentral

[drganjoo]

When attempting to run the smithy-rs published JARs directly, I'm encountering dependency resolution errors for Kotlin standard library artifacts. Specifically:

The following artifacts could not be resolved: 
org.jetbrains.kotlin:kotlin-stdlib-jdk8:jar:unspecified (absent)

This occurs despite having a valid smithy-build.json configuration with the correct smithy-rs dependencies:

"maven": {
    "dependencies": [
        "software.amazon.smithy.rust:codegen-server:0.1.3",
        "software.amazon.smithy:smithy-validation-model:1.62.0"
    ]
}

Environment details:

• JDK:

openjdk 17.0.16 2025-07-15 LTS
OpenJDK Runtime Environment Corretto-17.0.16.8.1 (build 17.0.16+8-LTS)
OpenJDK 64-Bit Server VM Corretto-17.0.16.8.1 (build 17.0.16+8-LTS, mixed mode, sharing)

Well how robust is the smithy CLI dependency resolver? Is it actually pulling transitive deps correctly and we just don't have the right configuration/POM or is it an issue with the CLI resolver.

The generated POM files contain an "unspecified" version:

<dependency>
 <groupId>org.jetbrains.kotlin</groupId>
 <artifactId>kotlin-stdlib-jdk8</artifactId>
 <scope>runtime</scope>
 <version>unspecified</version>
</dependency>

The same happens if we publish to local Maven.
