--------------------------------------
Summary: Cleaner way to support different languages
Key: MNG-5244
URL: https://jira.codehaus.org/browse/MNG-5244
Project: Maven 2 & 3
Issue Type: Improvement
Components: POM
Affects Versions: 3.0.4
Reporter: Martin Eisengardt
Maybe I did not get the point and there is already a way that I do not see.
Today the super pom is optimized for java. Let us say we want to use maven with
another language. Thats possible by adding for example a different source
folder to the pom. As a developer: If I set the packaging to "php" I would
expect that everything works "out of the box". That would cause maven to use
the source folder src/main/php or src/test/php instead of src/main/java and
src/test/php. I mean: Knowing about packaging "php" should be enough to set
some specific defaults without ever mention them in any pom.
As a plugin maintainer I did not yet see any way to let maven know about this
convention or standard. It always loads the super pom. A possible solution is
to advice every user of php-maven to use a parent-pom we will maintain. However
this would not be clever because in some projects there might be aggregates
that require to inherit a super-pom from a company. For example the following
project structure:
- parent.pom
+--- java-parent.pom
+--- java-library-1.pom
+--- war-project-1.pom
+--- php-parent.pom
+--- php-library-1.pom
+--- php-library-2.pom
As you see the php projects should have parent.pom as their parent. Adding
another parent that we will maintain is not possible.
Possible solution: As we already introduce our own packaging: Is there any way
to influence it by components.xml? What I am thinking of is something that
allowes maven to add a new mixing. Something to overwrite or extend the
super.pom mixing. I found out that the super pom is added as a mixin and that
the maven code should be able to handle multiple mixins (as far as I debugged
the code). Alothough I saw no option to add additional mixins.
