Wolfgang Knauf commented on ARCHETYPE-649:
------------------------------------------
Here is the slighly simplified source project, which reproduces the problem:
[^wildfly-jakartaee-ear-archetype_ARCHETYPE-649.zip]
In "pom.xml", there is a section where the archetype-plugin version can be
defined:
{{ <pluginManagement>}}
{{ <plugins>}}
{{ <plugin>}}
{{ <groupId>org.apache.maven.plugins</groupId>}}
{{ <artifactId>maven-archetype-plugin</artifactId>}}
{{ <version>3.2.1</version>}}
{{ <!--<version>3.1.2</version>-->}}
{{ <extensions>true</extensions>}}
{{ </plugin>}}
{{ </plugins>}}
{{ </pluginManagement>}}
Currently, it is "3.2.1", which reproduces the warning. If you build the
archetype with "mvn clean install", you will see the warning already when a
sample project is generated during the test.
Otherwise, you can create a project later with this command:
{{mvn archetype:generate -DarchetypeCatalog=local -DgroupId=foo.bar
-DartifactId=multi -Dversion=0.1-SNAPSHOT -Dpackage=foo.bar.multi
-DarchetypeGroupId=org.wildfly.archetype
-DarchetypeArtifactId=wildfly-jakartaee-ear-archetype_ARCHETYPE-649
-DarchetypeVersion=30.0.0.Final-SNAPSHOT}}
Change the version to "3.1.2" and rebuild it, and there is no warning.
The warning seems to be caused by the fact that the project has modules. In a
simpler archetype without modules, the problem does not happen.

> When creating a project from the archetype, the message appears with both
