[jira] Created: (MASSEMBLY-163) In a multiproject environment
Assembly causes many unneded rebuilds
In a multiproject environment Assembly causes many unneded rebuilds
--------------------------------------------------------------------
Key: MASSEMBLY-163
URL: http://jira.codehaus.org/browse/MASSEMBLY-163
Project: Maven 2.x Assembly Plugin
Issue Type: Bug
Affects Versions: 2.1
Environment: Linux Gentoo, Java 1.5.0_07_b3 sun, Maven 2.0.4, plugin 2.1
Reporter: Simone Gianni
I have a project subdivided in 10 modules. 2 of these modules uses the assembly plugin with the built-in descriptor "jar-with-dependencies".
When running mvn clean install (or also only maven install) from the root of the project, I see that every time it is building one of the two sub-projects that uses the assembly plugin, it rebuilds some already built projects, even if they are not dependencies of the "to be assembled" project, nor they have any other apparent motivation to be rebuilded. One of the two project using assembly doesn't even has a single dependency on other project, but triggers a nearly complete rebuild.
One of the projects is a WAR overlaying another war, useless to say that it consumes a lot of time, and gets built 3 times.
I've tested also with -o to exclude possible changes in external dependencies, checked all the dependency tree to make sure that there were no circular or otherwise "crossed" dependencies, changed the order of <modules> in the parent pom to the best build order, checked by hand starting from an empty local repository that building the artifacts (by hand, one by one, commenting out the assembly) in that order satisfies all the dependencies.

[jira] Closed: (MASSEMBLY-163) In a multiproject environment

John Casey closed MASSEMBLY-163.
--------------------------------
Assignee: John Casey
Resolution: Fixed
Fix Version/s: 2.2-beta-2
I'd suggest using the assembly:single goal (if you don't already). Also, since 2.2-beta-1, dependencies are only resolved on-demand, if they are needed for that particular type of assembly.

[jira] Commented: (MASSEMBLY-163) In a multiproject environment

----------------------------------------
We've encountered the same bug today and second the reported behaviour. This is critical since no workaround is known. We'd have to revise large portions of the build infrastructure or write our own plugin to fix. Please!

John Casey commented on MASSEMBLY-163:
--------------------------------------
which mojo are you binding into the plugin execution? If you're using assembly:assembly, assembly:directory, or assembly:attached, then you may see this behavior. (not entirely sure about assembly:attached, but I think it's in that group.) This is because these mojos were meant to be run outside the context of a normal build, and therefore fork a new lifecycle to build the package phase. To address this shortcoming for bound assembly-plugin use cases, we've created the assembly:single mojo, which assumes that it's bound into the lifecycle at the appropriate point to ensure that the resources it needs are available...you should give this one a spin.
