Maven 3 polyglot and/or attribute based configuration
Hi, I have long been a user of Maven, but disfavoured the xml verbosity. With Maven 3 I am aware of the polyglot capabilities of using Groovy or YAML for pom files, but I would still prefer the xml syntax for a while. A few years ago, a JIRA was raised [1], and an experimental branch created as a proof-of-concept, introducing attributed based configuration, having entities like: Which I think is a good format. It is easier to compact a full pom file and see what goes on, and it still verifies against a DTD. However, it may contradict existing tools and behaviours. Alternatively mix the current model with a namespaced schema-extension, which could provide attributed based primitives for the most common items. Does anyone know if this has been reconsider inside Maven 3 at all or is the polyglot solution the path to the future maven configuration? Regards Niels B Nielsen | Lead Engineer J.P.

RE: Handling native dependencies via classifier(s)
Well, I can tell you how I deal with it..
I have all editions of our native libraries bundled inside a single jar file, I
created.
./win32/libsomething.dll
./win64/libsomething.dll
./unix/x32/something.so
etc
and unpacks that into lib (similar to what you did).
During test and execution we navigate the right structure and set
java.library.path.
the eclipse plugin surely has some shortcomings, especially in the native ares.
When setting up for eclipse, I use 'mvn eclipse:eclipse -DdownloadSources
-DdownloadJavadocs', and then just reference the library in the launch
configuration (java.library.path).
Hope that helps.
P.S. I would never add a dependency on source and javadocs etc, as the main
resolve would transitively include these in the classpath.

My project depends on a 3rd party library for OpenGL + Java called JOGL
(http://jogamp.org/jogl/www/)
The library is currently not maven-ized and I'm trying to find the best
way to achieve that. My progress is documented at:
http://jogamp.762907.n3.nabble.com/maven2-artifacts-tp1935908p1935908.html
To get started I'm just manually putting the JOGL jars into a local
repository. Currently this is 4 jar files and each jar has a dependency
on a couple of native libs (.dll .jnilib .so etc) which I'm zipping and
then unpacking again for my project with:
maven-dependency-plugin
unpack-dependencies
generate-sources
unpack-dependencies
${basedir}/lib
zip
For each Jar I have a block like this:
com.jogamp.jogl
jogl-all
${jogl.version}
com.jogamp.jogl
jogl-natives
${jogl.version}
osx-universal
zip
Now this is going to get ugly quite fast, ie once I add all 5 supported
native platforms. It also feels wrong, although I'm very new to
maven2. Somehow I expected that there would be a way to tie the native
dependencies together with the jar in a more elegant way, maybe
something like:
com.jogamp.jogl
jogl-all
${jogl.version}
sources
javadoc
osx-universal
windows
linux
...
I considered some kind of wrapper pom for each jar, but it also feels
like a work-around. ie the jar can't be used without the natives, so
somehow they should be configured as a single artifact/entity/dependency.
The next issue I trip over with native handling, is eclipse:eclipse.
Looking at the sources, it seems to take account of classifiers for
'sources' and 'javadoc' but I don't see anything for handling of native
directories. ie the EclipseClasspathWriter and AbstractIdeSupportMojo
would need to output something like this:
Now I'm thinking I can't be the first person to trip over this, but
google isn't giving much help. So I'm wondering how other people are
dealing with this?
Or is it just that maven currently just isn't designed to work with
native dependencies?

Hi All,
I have a project(A) containing pom.xml and that have a dependency of
ca.grimoire.maven
maven-utils-parent
1.0
pom
And this maven-utils-parent-1.0.pom (in my local repository) has few
dependencies in . Is it possible to download these
dependencies via some command. As when I run dependency:resolve on pom.xml
of project A, I got ca.grimoire.maven:maven-utils-parent:pom:1.0 in my local
repository. Is there any other command which can download all dependencies
including below ones..
${project.groupId}
maven-utils
${project.version}
log4j
log4j
1.2.14
junit
junit
3.8.1
test
javax.servlet
servlet-api
2.5
provided
javax.servlet.jsp
jsp-api
2.1
provided
Thanks,
Amaresh

How do I augment the release plugin?
Hi, I would like to to utilize the maven-release-plugin (v 2.1) for one of our projects, but unfortunately I have a bit of a show stopper for actually doing this. The mojo's in the maven-release-plugin utilize the maven-release-manager, which has a set of predefined release phases, such as this (for branching) create-backup-poms check-poms scm-check-modifications map-branch-versions map-development-versions rewrite-poms-for-branch scm-commit-branch scm-branch rewrite-poms-for-development scm-commit-release end-release If I want to add additional phases in there, how would I go about doing it? I found the phases defined in a components-fragment.xml in the maven-release-manager plugin. I can see in the maven-release-plugin that it gets the MavenReleaseManager injected as a component, but I don't know if or how I can swap it out with a custom defined component. If anybody can point me to anything relevant I would be very grateful.. Regards Niels B Nielsen | Lead Engineer J.P.
