Re: RFC: Maven License Verifier Plugin
Hi Karl! It would be nice to have a plugin, that for each dependency checks the META-INF\manifest.mf for Bundle-License entry or tries to guess the licence type from META-INF\LICENSE.txt or META-INF\license files. It would be nice, if plugin takes care of autodetecting of licences of leave dependencies, which are not under our control, but for which we would like to check the license compatibility. It can warn the user, if the license type is not detected and can, for example, allow you to set the license for a given groupId/artifactId (and make this setting project-wide from parent pom). That would be a dream :) Or is it a reality already? Karl Heinz Marbaise wrote on 04/02/2010 00:15: Hi there, i have started with implementing some parts of a new Maven Plugin.

Re: RFC: Maven License Verifier Plugin
One important thing for me: It should be possible to define the configuration/license descriptors in my company pom. Then every dependent project should use the default configuration provided by the company pom. But it also should be possible to override/change/extend that configuration. Sample: Those two projects have the same company pom: - Library/reusable project that must not depend on artifacts under GPL. - Internal project that may depend on GPL Thanks, Johannes Karl Heinz Marbaise wrote: Hi there, i have started with implementing some parts of a new Maven Plugin.

Re: RFC: Maven License Verifier Plugin
Maybe have a look how the assembly plugin works with descriptors? Having pre-defined configs that can be referenced by id/name could be handy. However, I'm not sure if using a URL to download the descriptor/config is a good idea. I'm thinking that that could be misused by linking to configs outside your environment that change or can't sometimes be downloaded. I would start simple and then add new possibilities. What would be very nice, is if you implement this in modules so that the functionality can be used by other types of plugins as well, such as a Nexus plugin to verify this centrally in a repo manager. But I guess you could re-factor that later on. /Anders On Thu, Feb 4, 2010 at 00:15, Karl Heinz Marbaise khmarba...@gmx.de wrote: Hi there, i have started with implementing some parts of a new Maven Plugin.
