Re: ApacheCon / Thoughtworks TechRadar
FWIW the all-in-one bundle was there before and Alex coded most if not all of it :) If I remember correctly, building the all-in-one is supported by a rake task.

Re: ApacheCon / Thoughtworks TechRadar
Heya Tammo, So the goal LockJar is to provide a list of transitive dependencies that is consistent over time. This is why the dependency information is stored in the Jarfile.lock. Every dependency for a project should be resolved to the Jarfile.lock. This prevents conflicts that can appear from ad hoc resolution of dependencies when their transitive dependencies overlap. LockJar already has the concept of group. There is always the default group, but you can add any additional group you want. All of LockJar's actions (list,load,etc) can handle group. The perk of the LockJar integration is it automatically populates the compile and test task classpaths. That being said, the integration with LockJar does not have to be used. I am a bit basis, but I like seeing the dependency information in the buildfile. You can actually skip the locking and have LockJar resolve every time using something along the lines of: dependencies = LockJar.list ( :resolve = true ) do jar 'org.eclipse.jetty:example-jetty-embedded:jar:8.1.2.v20120308' end compile.with project('api'), dependencies Or if you want to use a single Jarfile for all projects, than you could call dependencies = LockJar.list(['test']) ... test.with project('api'), dependencies So, uh, I should point out I have not updated LockJar's buildr integration lately, since I have been in the land RoR. Mostly I have not put much time into it, since there does not appear to be a lot of interest in it. thanks, Michael On 11/10/2012 06:46 AM, Tammo van Lessen wrote: Hi Michel, I did have a look at lock_jar and I really like the idea.

However, it was difficult to me to grok how a real-world multi-project buildr file would look like. If I'm not mistaken, I would need to add all dependencies separately to the projects using the lock_jar dsl? I'd love if there would be a more unobtrusive way like saying compile.with project('api'), lock(AXIS2, AXIOM, OPENJPA) test.with lock(TESTNG) and lockjar would use this information to create the lockfile (automatically if not there, otherwise on demand) and return a resolved set of dependencies. The lock method could also take an optional group parameter in order to define independent resolution groups. Still open would be the question how excludes or pinned versions could be expressed. Do you think such an integration would useful or feasible?
