Yes Robert, I thought about that too. But looking at it in detail, I realized that this might get pretty tricky.
1.) not all poms have a <license> section. macker doesn't for example [1] 2.) in some plugins, we explicitly fork a new jvm and kind of call those GPL licensed products 'via commandline'. This is legally ok, but it's hard to automatically detect the differences. It would for example be extremely hard in cobertura where some classes are GPL and others are ASL-1 licensed :( Any ideas anyone?

To: [email protected] Date: Monday, May 17, 2010, 7:10 PM Reading these messages, it seems like we could add a goal to the ianal-m-p, namely 'verify-code' to check the usage of imports/FQN in combination with the license of it's artifact. I'm pretty sure most of us aren't lawyers, so it would be nice to have a plugin which could help with these delicate issues. - Robert > Date: Sun, 16 May 2010 16:25:47 -0700 > From: [email protected] > To: [email protected] > Subject: Re: [mojo-dev] [legal] mojo plugins for GPL licensed core libs? > > BTW, Codehaus forbids GPL licensed project > > -Dan > > On Sun, May 16, 2010 at 3:29 PM, Mark Struberg <[email protected]> wrote: > > Yea, that would be an option to write an interface and pull in the actual > > implementation via java.util.ServiceLoader or simply classForName. > > > > As far as I read the codehaus licensing guidelines [1] we are _not_ allowed > > to host GPL licensed plugins at codehaus. > > > > LieGrue, > > strb > > > > [1] http://codehaus.org/customs/licenses.html > > > > --- On Sun, 5/16/10, Stephen Connolly <[email protected]> > > wrote: > > > > From: Stephen Connolly <[email protected]> > > Subject: Re: [mojo-dev] [legal] mojo plugins for GPL licensed core libs? > > To: [email protected] > > Date: Sunday, May 16, 2010, 10:22 PM > > > > IANAL, > > > > If the GPL code has tainted the macker-maven-plugin, then we need to change > > the license on macker-maven-plugin to GPL... a change that AFAIK is > > possible (i.e. you can go ASL-2 -> GPL you just cannot go GPL -> ASL-2 ) > > > > > > I guess the question is has it been tainted? > > > > When dealing with GPL libraries, if you want to keep yourself taint free > > the best way is to interface via an API that has multiple implementations, > > that way you can prove that the GPL code is only dynamically linked with > > your code and as there are non-GPL implementations of the API, everything > > is hunky-dorey > > > > > > As java is all dynamic linking (except for uberjars) the question of taint > > basically boils down to what API the library you are using is... for > > example, if you write a JDBC client, IANAL but my understanding is that it > > can safely be ASL-2 even if 99.99% of the time it is using a GPL JDBC > > driver. > > > > > > So for example with the vcc.dev.java.net project, I have designed a > > virtualization api independently from any of the implementations... the api > > is ASL-2... the fact that the xen implementation of the api will have to be > > GPL is OK, because I have the ASL-2 licensed VMware implementation as the > > reference implementation. > > > > > > -Stephen > > > > On 16 May 2010 11:58, Mark Struberg <[email protected]> wrote: > > > > Hi! > > > > > > > > I recently tried to help with the macker-maven-plugin [1] and figured that > > macker [2] itself (the underlying library being used) is GPL licensed. > > > > > > > > So, since the Mojos in macker-maven-plugin import files from the macker > > library, this imo conflicts with the ASL-2 license used in the > > macker-maven-plugin.
