"[WARNING] CP Don't override file" when generating archetype with jboss-parent 40

[WolfgangHG]

During the build process, there are warnings printed after updating to jboss-parent 40:

The archetype plugin was updated from 3.1.2 to 3.2.1, which seems to cause this issue.

According to some web research, the reason might be that some filesets in the archetype-metadata.xml are overlapping. I will do further research.

[WolfgangHG]

The problem seems to be caused in the moment when the archetype is created and depends on the archetype plugin version.
When generating a project from the archetype with debug logging, I can see that the jar file of the archetype contains much more entries after having build it with jboss-parent 40 (which uses archetype plugin 3.2.1). Those additional entries seem to be directory entries.

Here is the log for a "archetype:generate" output, when the archetype is built with maven-archetype-plugin 3.2.1:

[DEBUG] getFilesetArchetypeResources( "C:\Users\USERNAME\.m2\repository\org\wildfly\archetype\wildfly-jakartaee-ear-archetype\30.0.0.Final-SNAPSHOT\wildfly-jakartaee-ear-archetype-30.0.0.Final-SNAPSHOT.jar" )

And this is the log output, when the archetype was built with jboss-parent 39 (archetype plugin 3.1.2):

[DEBUG] getFilesetArchetypeResources( "C:\Users\USERNAME\.m2\repository\org\wildfly\archetype\wildfly-jakartaee-ear-archetype\30.0.0.Final-SNAPSHOT\wildfly-jakartaee-ear-archetype-30.0.0.Final-SNAPSHOT.jar" )

[DEBUG]   - ignored resource META-INF/maven/archetype-metadata.xml
[DEBUG] Processing complete archetype wildfly-jakartaee-webapp-ear-archetype

The jar files differ also in size.

The method "getFilesetArchetypeResources" is found here. It simply reads the zip entries.
So I assume that duplicate entries cause the duplicate warning.

Created https://issues.apache.org/jira/browse/ARCHETYPE-649 - let's see if there is some feedback.

[WolfgangHG]

archetype-plugin 3.3.0 brings a new problem: logging of the archetype verification is no longer reported, which is confusing as there is just a long delay after the line "Invoking post-archetype-generation goals: verify" is printed, and you won't see errors that happen during building of the sample project:
