Fedora 21 Eclipse m2e-wtp plug-in package

[Julius Schwartzenberg]

Hi,

I'm trying out the Fedora 21 Eclipse builds and I'm quite impressed with
all the things which can be cleanly installed through Yum/RPM!

However it appears that the m2e-wtp (1) plug-in hasn't been packaged
yet. It is the only missing piece for building and running Maven
projects in (at least) Tomcat in Fedora 21 out of the box.

Am I correct that such a package is currently unavailable at all? Would
it be possible for me to contribute such a package? Is there any guide
available on creating RPMs for Eclipse plug-ins?

Thanks in advance,
Julius

Hi Julius,

That's great that everything is working easily for you, and that you
want to help make it better!

You're correct that there isn't a Fedora package for m2e-wtp yet. I
think it would be great if you added it.

I'm not aware of any Eclipse specific packaging documentation (maybe
someone else will point us in the right direction for this), but m2e-wtp
is built using maven, and there's lots of documentation on that.

The main Java packaging guidelines page is available at [1], and there's
also a great HowTo page[2].

A good idea might be to have a look at some existing packages that are
similar. For example, some other m2e packages exist in Fedora[3].

Are you already a Fedora packager, or do you have any other experience
with RPM packaging?

Gerard.

Hi Gerard,

Thanks for the quick reply!

I guess I should try building one of the existing packages and maybe use
its spec file as a starting point.

I've come across multiple projects like the Maven RPM plug-in, but also
an RPM plug-in for Eclipse. I wonder if these also (can) play a part in
the process of packaging specifically Eclipse plug-ins for Fedora.

My only experience with RPM packaging is building exists spec files and
source RPMs with rpmbuild and some minor tweaks. I did once create some
spec files from scratch, but that was around 10 years ago.

Best regards,
Julius

Yes, this is a great idea. Like with anything, the more good examples
you see, the more you'll understand what you'll need to do (and how easy
it's now becoming!).

At the moment, none of these things are used for packages in the main
Fedora repos. As you'll see from the documentation though, it's probably
easier than that though, once you get used to the relevant RPM macros
for maven projects.

Cool, so you have a little exposure. There's a plugin package called
eclipse-fedorapackager. It's not specific to Eclipse/Java
packaging...it's useful for all packaging in Fedora, especially when
you're familiar with the IDE already.

The #fedora-java channel on Freenode IRC, or here on this mailing list
are great places to come if you run into any problems or have any
questions while packaging it :)
