1 Module - N output jars
Hi all, I'm currently migrating a big project from Ant to Maven. I have exploded the source code in modules as much as possible but for legacy reasons I want one of them to generate N output jars (instead of a single one). My question is How can I do that? I have several leads but some questions remain. Here they are : 1. add to package phase an antrun plugin to create the desired jars, but then the underlying question is: how to disable the 'jar:jar' goal during this phase? 1bis. use the assembly plugin to build several jars, sounds quite cumbersome and not better than the ant plugin solution. 2. is there a way to make the jar plugin generate several jars? Thanks for your help! Alexis
RE: 1 Module - N output jars
1. Are you sure you need to disable jar:jar? Or just modify it such that it builds one of your desired jars? I also needed to generate multiple jars for a project; you can read about my particular solution here: http://www.nabble.com/-maven2--Generating-several-artifacts-per-project- --tf1689630.html#a4630045 2. Don't know, but hopefully answer 1 will make this a moot point.

Re: 1 Module - N output jars
well disable the jar:jar is not a requirement, but if I generate several jars, I do not need the jar:jar goal to create a big jar containing all classes. you see what I mean? by the way, your answer is really appreciated. I did not know the build-helper-maven-plugin up until now. Regards, Alexis On 7/27/06, Chris Hilton [EMAIL PROTECTED] wrote: 1. Are you sure you need to disable jar:jar?

RE: 1 Module - N output jars
Right, but you can designate one of the jars you want to create as the primary jar for Maven's purposes, even though this may mean nothing to you, and then configure the maven-jar-plugin with the appropriate includes/excludes to create that jar. Then use the other technique to create your secondary jars and attach them. -Original Message- From: Alexis Midon [mailto:[EMAIL PROTECTED] Sent: Thursday, 27 July, 2006 12:14 To: Maven Users List Subject: Re: 1 Module - N output jars well disable the jar:jar is not a requirement, but if I generate several jars, I do not need the jar:jar goal to create a big jar containing all classes. you see what I mean? by the way, your answer is really appreciated.

At 12:48 PM -0400 7/27/06, John Casey wrote: One of the fundamental principles that Maven operates on is the 1:1 association of POMs to primary output artifacts (not counting special assemblies, source, or javadoc jars). If you want, you might be able to construct a set of POMs that all reference the same source directory, and setup compiler excludes configurations such that each POM generates a jar based on a different subset of the sources in that single directory... I wonder why the compiler-plugin doesn't let us set the output directory so we don't have to propogate poms? (snipet from maven-compiler-2.1-SNAPSHOT/META-INF/maven/plugin.xml): parameter nameoutputDirectory/name typejava.io.File/type requiredtrue/required editablefalse/editable descriptionThe directory for compiled classes./description /parameter This seems to be a common design feature in many of the standard plugins - they are only tested for one instantiation per build cycle, and give the user little control over the configuration of secondary executions. Or is there a hidden way to configure the default execution such that the configuration won't override subsequent executions of the same plugin? The only way that seems to be implied is to use a configuration element in parallel with executions, i.e.: projectbuild ... plugin artifactIdmaven-some-plugin/artifactId configuration [A] /configuration executions execution configuration [B] /configuration In the plugins I tried, [A] trumps [B] (jar-plugin, resources-plugin, surefire-plugin) But why would I specify [B] if I wanted to use [A]? In other words, the [A] configuration seems to be recognized for the default (or implied) execution of say, the jar-plugin, but in specifying [A], we no longer have [B] available. On the other hand, if we specify: executions execution configuration [B] /configuration /execution execution configuration [C] /configuration /execution Then I can successfully provide 2 configurations in addition to the implied, untouched configuration. What this means in the case of the jar-plugin, is, we get 3 executions instead of 2 in order to create 2 jars. One jar is wasted. This is true regardless of whether or not we use ant, since there appears to be no way to turn off the default jar execution during packaging. (This is a case where the source tree is generated as a unit, and then packaged into two non-overlapping jars). Or, again, is there an way to specify a configuration for the default execution with some magic id element? Bottom line is I think that if I go to the trouble of specifying an configuration for an execution, then mvn should use it, and we should have clearly defined semantics for plug-in writers on how to handle the scope of a configuration element. This would greatly reduce the amount of ant code that is required in an m2 project, especially a large legacy project where we don't necessarily have the luxury of implementing the one-artifact-per-pom dogma pervasively. In the case of the jar-plugin, simply providing include/exclude elements would go a long way in solving our particular packaging problems, but this would have to be in addition to a fix for the configuration scoping problem outlined above. -Russ On 7/27/06, Alexis Midon [EMAIL PROTECTED] wrote: Hi all, I'm currently migrating a big project from Ant to Maven.

RE: 1 Module - N output jars
So, just to keep this thread up-to-date, according to the other email I just read (RE: How to deselect classes while creating jar? from Simon Kitching), you can't exactly do what I outlined below because the jar plugin does not support includes/excludes yet. Please vote for http://jira.codehaus.org/browse/MJAR-30. Until then, I guess you will have to create one big jar with everything and all of your custom jars will be secondary artifacts.
