Subject: project internal dependencies in a multi-module project
"Hello everybody,
I'm working on a quite big project using a maven multimodule project
layout. I learned quite a lot about Maven the last month and I'm happy
to use this tool.
Currently, I'm wondering about a issue, I couldn't find a guide or a
hint for best practice for.
I'm using a dependency management section at the root pom for managing
project external dependencies like mysql connector, or spring framework
version.
It is perfectly clear to me, to use dependency management here.
But what about project-internal dependencies? Should I also include each
leaf of my project tree (i.e. each module with packaging type jar) in
the dependency management section, with the project.version as its
version?
Like this?
<dependency>
<groupId>ourGroup</groupId>
<artifactId>rootmodule.submodule1.subsubmodule1</artifactId>
<version>${project.version}</version>
</dependency>
What is the best practice here?"
I think you nailed it.
That's the practice I use.
"Furthermore, if I run a compile on the root pom, I get the feeling,
that maven does not try to find project-internal dependencies by
traversing the multi-module-project, but looking up the local
repository. Can this behaviour be changed? Otherwise, I always have to
redeploy the modules, other modules depend on, to the local repository
before I can compile the module itself...
I hope you get the problem!
Nonetheless, thanks a lot for this great tool, that really helps me
developing and following good development practice!"
Maven builds up the compile order based on the modules pom's.
It will try to compile your active code aka. your modules.
So no, it will not look in the repo for the artifact if it's a module in
your project.
Removing it as a module, but keeping it as a dependency will make it
look in the repo.
"Regards,
Flo"
