kie-maven-plugin:10.1.0 failing on Maven 3.10 due to API Incompatibility (NoClassDefFoundError / Aether)

[chakravarthula bharani kumar]

Hi Team,

I am attempting to compile a project using kie-maven-plugin version 10.1.0 alongside Apache Maven 3.10, but the build fails due to an API incompatibility.

The build throws a NoClassDefFoundError related to the Eclipse Aether resolver packages within the Plexus/ClassWorlds realm, indicating that the plugin is looking for a class structure or method signature that has changed or been removed in Maven 3.10's core libraries.

[ERROR] Failed to execute goal org.kie:kie-maven-plugin:10.1.0:build (default-build) on project...
[ERROR] Execution default-build of goal org.kie:kie-maven-plugin:10.1.0:build failed: An API incompatibility was encountered while executing org.kie:kie-maven-plugin:10.1.0:build: java.lang.NoClassDefFoundError: org/eclipse/aether/...
[ERROR] realm =    plugin>org.kie:kie-maven-plugin:10.1.0
[ERROR] strategy = org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy
[ERROR] urls[0] = file:/...

Environment Details:

• Maven version: 3.10.x
• KIE/Drools version: 10.1.0
• Java version: 21

Observations:
Downgrading the local Maven environment back to Maven 3.9.x completely resolves the issue, confirming that the plugin struggles with the upgraded dependency resolution APIs in Maven 3.10.

Thanks & Regards

Hi,

AFAIK we tested only with Maven 3.9.x and it is a known requirement, but now I'm not sure if it is properly documented.

Cheers

Gabriele
