microsoft-kiota-** dependencies have conflicting Automatic-Module-Name

components/**/build.gradle の tasks.jar マニフェスト設定を調査し、提供された pom.xml と文書化されている jdeps コマンドを使って競合を再現します。生成された Kiota JAR が重複した com.microsoft.kiota モジュール名を生成しなくなり、jdeps が正常に完了することを確認します。

We use for our projects both jdeps and jlink tools to generate a slim JRE. However since the switch to com.microsoft.graph:microsoft-graph:6.4.0 (v6 of the SDK, recently released), which builds on top of the microsoft-kiota-** dependencies. We can't seem to run our jdeps command succesfully anymore.

Previously (without the microsoft-kiota-** dependencies on the class-/module path we have been using the following command; (exectued from target/)

jdeps --multi-release base --recursive --ignore-missing-deps --print-module-deps --class-path="./lib/*" --module-path="./lib/*" -quiet demo-0.0.1-SNAPSHOT.jar

Which would list something like this; java.base,spring.boot,spring.boot.autoconfigure,spring.context,spring.core

Note: When running this on a Windows machine, be sure to change ./lib/* to ./lib (as there is an issue with the * wildcard.

Howafter after switching to com.microsoft.graph:microsoft-graph:6.4.0 we not get the following exception when we run the same command;

Exception in thread "main" java.lang.module.FindException: Two versions of module com.microsoft.kiota found in .\lib (microsoft-kiota-authentication-azure-1.0.4.jar and microsoft-kiota-abstractions-1.0.4.jar)

A quick look here in the repository shows me that all components/**/build.gradle files are containing this piece of code;

tasks.jar {
    manifest {
        attributes('Automatic-Module-Name': project.property('mavenGroupId'))
    }
}

So the Automatic-Module-Name is set to an unique value, which isn't correct in my opinion. Might be better to use the artifactId here maybe? But that is up to you guys ;)

Following pom.xml file can be used to simulate this issue. Note the maven-dependency-plugin which copies all the dependencies (on mvn install) to target/lib for easier testing with the command.
