Can maven-ant-plugin create a Felix bundle?
Is it possible for maven-ant-plugin to generate a build.xml file that
will create a Felix bundle?
Without changing my pom.xml, I ran "mvn ant:ant: to generate a build.xml
file. Running ant on that build.xml does create a jar file that
installs and resolves in Felix but it certainly doesn't execute.
Documentation on maven-ant-plugin is a bit slim. It just describes the
one goal (ant:ant) with its two parameters (localRepository and project||).
Perhaps I'm expecting too much from maven-ant-plugin?

If an Ant build file is generated at the same as the sources are
released, then Maven is completely removed from the build process.

In your pom, you can specify (the mininum only) Maven version needed

You cannot make a release with snapshot dependencies.

Most of the Maven process is manage by plugins and you can specify a precise version of plugins to use in the pom of your project. Maven core itself is actually missing...
Hope it helps,
Damien

In my personal opinion, this is certainly a worth-while thing to do.
I agree with your observations about Maven pulling in lots of
resources when doing a build.
For public releases, this might be a problem. I am not a Maven
expert, but let's assume we do a source release of Felix now and
three years from now we get this archive and try to build it again.
The only truly reproducable way to do that is to make sure that both
the Maven version and the versions of all required dependencies are
exactly the same as they were at the time of the release. That also
means we need to specify which Maven version to use when we create a
release. Currently, I don't see how we can do that (and how even to
"freeze" snapshot versions of dependencies, which seems to be
completely impossible). The only work-around would be to include a
full copy of Maven and all its dependencies in each release.

Maybe just because nobody knows. Your insights and findings might
probably be worth some lines in the wiki ...

Personally, I would love this capability. That is how I would like to
Felix releases. I hate having to depend on network connectivity to have
the build work. I want our releases to be completely self-contained. So,
if this were available, we would definitely consider using it for future
Felix releases too.

I just starting playing with bnd this evening. I will definitely
investigate this further.
Thanks for the tip. :)

The bnd program is also an ant task. It should be quite
straightforward to take the pom and transfer this to a bnd file, the
<instruction> elements of the maven plugin are the same as the bnd
files headers. Your ant script then only has to compile the sources
and run the bnd task.

Thanks for the reply.
I too primarily use Maven since I think that Maven is awesome. However,
it is not nearly as pervasive as Ant and it is a bit "needy".
It needs access to the Internet, not only to get project dependencies,
but to also get all of Maven plugins, which can be quite a lot. For
those without access to the Internet, this is a problem. Granted, you
can initially build on an Internet-connect machine, then move the local
repository to the disconnected machine. However, the local repository
includes a lot of dependencies for someone who just needs to build the
software but not do development.
My hope was to use Maven to do development of a project on an
Internet-connected machine. Then, when the project is released, I would
also release the project's sources, an ant build.xml file, and all the
project's dependencies. This would be the smallest complete set of
requirements for someone to build the project from source. This set of
requirements would be much less than those required to build the project
using Maven.
Perhaps this is just too much to ask. Thanks again for the reply.
