Re: Conditional dependencies
Hi Michael, thanks a lot for your answer. This is how we are currently doing it. In reality our scenario is a bit more complicated than the given database example. We have many artifacts (like A and B), and a whole lot of connection parts (like A2B), that would be better placed in their own artifacts, provided that they are used when both artifacts are in the classpath, and we don't want to have the user bother with these connection artifacts. Also because A and B could arrive in the classpath via transiitive dependencies, so the user have no idea (if not doing a dependency:tree) that they are there and the connection part A2B is missing. As a last resort, do you think a plugin can handle these dynamic dependencies? Can a plugin add dependencies to the project, and then have them resolved and used in the rest of the build lifecycle? Maybe binding to one of the early phases?

Conditional dependencies
Hi all, I would like to include or exclude a dependency based on the presence of an artifact on the global class path. For example, I have a database project. The user will include a dependency on it in his own pom. The user will also add a JDBC driver artifact. My database project should be able to declare additional dependencies depending on the presence of specific JDBC drivers artifacts, for example a database-mysql-dialect if the mysql-connector is used, or the database-postgres-dialect if the postgres driver is used. Whle it is possible to check at runtime, using reflection and the like, the presence of a given class, it lacks versioning, it is not a clean way, it clutters the main package code with stuff that could (and should) be placed in different artifacts. I don't know any way to do this in Maven right now. Theoretically, it could be achieved with profile activation, if there was a profile activation based on the presence of an artifact or at least on the presence of classpath resources instead of plain files. Is it possible to implement such a profile activator? Has anybody ever done something like this? Has anybody had the same need and investigated a way to solve it?

Re: conditional dependencies
The problem I see with conditional dependencies is that they define the dependencies that Maven needs in order to build/test the artifact. So if I do a build on java6, my conditional dependencies will exclude javax.activation... I assume the Release/deploy plugins will upload the effective pom for my build environment, which does not include javax.activation... Now you come along and depend on my artifact, but are building with java5... so you do not receive the conditional dependency. On the other hand if the release/deploy plugins upload the pom and it's profile definitions, Maven is going to have to re-detect the profile activation to determine the transitive dependencies (Which I don't thinkk it does) -Stephen On Feb 5, 2008 8:20 AM, SlinnHawkins, Jon (ELS-CAM) [EMAIL PROTECTED] wrote: Hi Jorg Yeah just set up profiles for Java5 and java6 each specifying the unique dependencies for the jdk.

If you can't/won't create the various profiles to support this functionality, I think you're going to need to write a plugin (or two) to do all this.

Conditional dependencies in M2
Hello all, I am converting from Ant/Ivy to Maven2 and I have a question regarding dependencies in Maven2. In Ivy I could define dependencies which would be conditionally considered based on my build configuration. for example, I could define in a project Foo, a dependency on Bar for all configurations and a dependecy on Box for the test configuration of project Foo. Then, another project, say Fuzz, could depend on Foo and use either its default configuration (which would transitivly bring in Bar but not Box) or use its test configuration (which would transitivly bring in Bar AND Box). How is this done in Maven? I read up on profiles and I'm wondering if that's the answer, or if there's a more straight foward way of doing the same. Could somebody provide an example of a Maven equivalent? Thanx in advance. --- Clifton C.

Re: [m1] Conditional dependencies
From: Brett Porter [EMAIL PROTECTED] This is a bit dangerous. Agreed. :) But it works. 1) a project will have a different model depending on that property. It will ripple into needing to change other things like the final name of the built artifact to ensure you don't end up with one thing sometimes being something different Actually... that's the intent. We build a .war file, and it contains whichever JSF implementation you choose-- different .jar files in WEB-INF/lib, web.xml filtered one way or another, but the name of the .war file remains the same. (Remember that this is an existing Ant build...) This is a little bit of an unusual use case. It's understandable that you often depend on a spec dependency (for which we don't yet have great support) and an impl goes into the final bundle and the impl might change. Changing the API too is what is unusual. I agree... but that's the requirement. Anyway, in m1 the general approach to this is to have two projects that do the different bundling and build whichever you want, sharing the common code. I'm not sure if that's easily done when the api is changed though. I've just been introduced to the leave the project structure alone and put all the build files in a completely separate directory structure concept. Most of my problems (like building three artifacts out of a single source tree) might just go away. Reorganizing the project itself to suit Maven is definitely not something I want to have to push for. I replied in this fashion in another thread. I should also mention again that environmental changes to project builds are supported in Maven 2. (I missed your earlier responses, thanks for pointing them out.) Okay, okay... I'll look at m2 again. :) Last time it seemed like not enough of the plugins I needed were ready yet. -- Wendy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: [m1] Conditional dependencies
Wendy,
Jay, this turned out to work *perfectly*!
Glad to hear it, though I agree with Brett that it doesn't necessarily fall
in the category of Best Practice. I'm glad to hear Maven 2 will do a
better job of dealing with this kind of issue.
One concern was having duplicate artifacts with the same name but different
contents. If you haven't already, you might consider using the same property
in the artifact ID:
artfactIdmyproject-${maven.shale.jsf.impl}/artifactId.
You could also manipulate maven.final.name, I guess, but I think SNAPSHOT
builds already do this, so you could end up with conflicts if you did it in
the wrong place.
Similarly, you could sprinkle that property around in other places to cause,
for example, the site to deploy to a different location with a different
title and slightly different description.
Effectively you end up with two different object models that just happen to
share the same codebase.
Good luck,
Jay

RE: [m1] Conditional dependencies
Wendy,
I can't say I've had this exact problem, but I can think of two approaches
I'd consider:
1) Create a separate project, let's call it jsf. Have all the RI/MyFaces
jars listed in its dependency list. No code is involved, but the build
produces two artifacts, both uberjars (not that you'd use the deprecated
plug-in) that incorporate all the classes needed for each option. Then your
existing approach with single-jar substitution based on a property will
continue to work.
2) Create two different parent project files, and have the extends
parameter depend on a property:
project
extends${jsf.project.file}/extends
...
/project
Those base project files list the dependencies for the appropriate option.
You can use the same property to determine how to filter the web.xml file. I
did a quick test of this, and both ${pom.extends} and ${pom.dependencies}
appear to have gotten modified as I expected. I haven't verified that code
compilation, war bundling, etc. work, but since the object model appears
correct I would expect everything else to work.
I'm sure you could also script up a plug-in, but these two approaches seem
relatively simple to me with minimal modifications to your existing scripts.
Hope this helps,
Jay

$ maven -p myfaces-project.xml build-all
depending on which JSF implementation you want to use? I'm not sure I want
to start down that path, given that there may eventually be multiple JSF
implementations from which to choose.
What would you do in this situation?
If you want to take a look at the files:
http://svn.apache.org/viewcvs.cgi/struts/shale/trunk/
or
$ svn co http://svn.apache.org/repos/asf/struts/shale/trunk/ shale
(If you want to try to build it, read this first:
http://wiki.wsmoak.net/cgi-bin/wiki.pl?ShaleMavenBuild )
Thanks for any advice! I note that there is only one thread on this topic
in the archives... one post, with no replies.

Conditional dependencies
I have a dependency for an EJB jar that should only be present if packaging for the WAS userdefined goal. How may I include/exlude dependencies?
