Dynamic Dependency
Hi,
in the rat-maven-plugin we currently have a hard cored dependency from
the plugin to the rat core with the same version number. In other
words, if one would like to use a different version of the rat core,
one needs to use a different version of the plugin.
This has got an important disadvantage: We can't release the core
alone. Instead, a Rat release
consists of a bunch of jar files, making the release process slow,
burdensome, and generally something that we hesitate to do. (As
opposed to "Release early, release often".)
Now, I am well aware that I can use a different version of the Rat
core by declaring it in the plugins extension list, bt my feeling says
that this is not as it ought to be. I'd rather declare a version
number in the plugins configuration (the default being hard coded into
the plugin), and load that version dynamically.
Now my questions:
Is that possible right now?
If so: How?
If not: There are quite a number of other plugins with the same
construction, which could benefit
from such a possibility. (To name but a few: cobertura-maven-plugin,
antlr-maven-plugin, jaxb-maven-plugin, and so on.) Would you welcome
some work in that direction? Would someone offer being a Mentor if I
worked on that?
Thanks,
Jochen

Hello all,
The jaxb2-maven-plugin declares the JAXB libraries as dependencies within
the plugin, and
hence permits the user to override the JAXB libraries at runtime.
Note, however, that system-scoped dependencies (such as tools.jar) will
need some special treatment
as the plugin needs to augment its runtime classpath to add them.

This approach works for every plugin...

Thanks for the hint, I will check that out.

I have never used the Rat plugin, but the Maven Checkstyle plugin
supports something like this, by declaring checkstyle as a dependency
of the plugin[1], which can be overridden at runtime in the end user
pom configuration[2].
