> Maven archetype overwrites parent information
> ---------------------------------------------
>
> Key: MPLUGIN-49
> URL: http://jira.codehaus.org/browse/MPLUGIN-49
> Project: Maven 2.x Plugin Tools
> Issue Type: Bug
> Reporter: Peter Liljenberg
> Priority: Critical
>
> When creating a new archetype that I want to use for my projects I ran into
> some trouble with the created/copied pom.xml.
> The archetype pom.xml (\src\main\resources\archetype-resources\pom.xml) looks
> like this:
> <project>
> <parent>
> <groupId>group</groupId>
> <artifactId>masterpom</artifactId>
> <version>1.0</version>
> </parent>
> <modelVersion>4.0.0</modelVersion>
> <groupId>group</groupId>
> <artifactId>${artifactId}</artifactId>
> <version>1.0</version>
> </project>
> When I run my archetype it creates a pom.xml that looks like:
> <project>
> <parent>
> <artifactId>integration</artifactId>
> <groupId>group</groupId>
> <version>1.0</version>
> </parent>
> <modelVersion>4.0.0</modelVersion>
> <groupId>group</groupId>
> <artifactId>test</artifactId>
> <version>1.0</version>
> </project>
> Where "integration" is the name of the pom in the folder that I'm running mvn
> archetype:create from.
> Digging into the source we find in DefaultArchetype.java that processTemplate
> is indeed reading the parent pom and overwriting whatever was found in the
> original pom.xml.
> Is this really what we want to achieve? It should be possible to keep the
> parent-pom from the pom.xml in the archetype since it reduces the need for
> all developers to change their newly created pom.xml.
> <code>
> processTemplates
> if ( parentModel != null )
> {
> Parent parent = new Parent();
> parent.setGroupId( parentModel.getGroupId() );
> if ( parent.getGroupId() == null )
> {
> parent.setGroupId( parentModel.getParent().getGroupId() );
> }
> parent.setArtifactId( parentModel.getArtifactId() );
> parent.setVersion( parentModel.getVersion() );
> if ( parent.getVersion() == null )
> {
> parent.setVersion( parentModel.getParent().getVersion() );
> }
> generatedModel.setParent( parent );
> </code>
> Two alternative solutions:
> * If the parent-pom is specified in the archetype-pom, don't replace it
> * A parameter that we can supply that will leave the archetype-pom parent
> setting untouched.
> I vote for solution number 1....
