Helidon maven archetypes fail with maven-archetype-plugin version 3.3.0

[barchetta]

Environment Details

• Helidon Version: 2.x, 3.x, 4.x
• Helidon SE and Helidon MP

---

Problem Description

Running a legacy Helidon maven archetype to generate a project fails.

mvn -U archetype:generate -DinteractiveMode=false \
    -DarchetypeGroupId=io.helidon.archetypes \
    -DarchetypeArtifactId=helidon-quickstart-mp \
    -DarchetypeVersion=4.1.1 \
    -DgroupId=io.helidon.examples \
    -DartifactId=helidon-quickstart-mp \
    -Dpackage=io.helidon.examples.quickstart.mp

. . .

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.3.0:generate (default-cli) on project standalone-pom: 
  Execution default-cli of goal org.apache.maven.plugins:maven-archetype-plugin:3.3.0:generate failed: 
  An API incompatibility was encountered while executing org.apache.maven.plugins:maven-archetype-plugin:3.3.0:generate: 
  java.lang.NoSuchMethodError: 'org.apache.maven.project.ProjectBuildingRequest org.apache.maven.archetype.ArchetypeGenerationRequest.getProjectBuildingRequest()'

Why has this started failing now? Because on 22-Sep-2024 version 3.3.0 of maven-archetype-plugin was released that introduced an incompatibility. See PR 215

Workaround

The workaround is to use version 3.2.1 of maven-archetype-plugin:

mvn -U org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate  -DinteractiveMode=false \
    -DarchetypeGroupId=io.helidon.archetypes \
    -DarchetypeArtifactId=helidon-quickstart-mp \
    -DarchetypeVersion=4.1.1 \
    -DgroupId=io.helidon.examples \
    -DartifactId=helidon-quickstart-mp \
    -Dpackage=io.helidon.examples.quickstart.mp

Or even better us the Helidon CLI:

helidon init  --version 4.1.1
