[jira] Closed: (MASSEMBLY-194) unnecessary dependency expansion regression

["John Casey (JIRA)" <ji...@codehaus.org>]

     [ http://jira.codehaus.org/browse/MASSEMBLY-194?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

John Casey closed MASSEMBLY-194.
--------------------------------

    Resolution: Fixed

I've added a new flag to the dependencySet: useTransitiveDependencies.

Use:

{code:xml}
<useTransitiveDependencies>true</useTransitiveDependencies>
{code}

if you want to open up the transitive dependencies to filter, unpack, inclusion/exclusion, etc. operations happening in the dependencySet.

Use:

{code:xml}
<useTransitiveDependencies>false</useTransitiveDependencies>
{code}

if you want to exclude all transitive dependencies from processing in that dependency set.

The default value is currently true. I've also added a new integration test, called 'dependency-sets/dependencySet-nonTransitive' to verify this behavior.

> See the attached test project. It requires that you've run mvn clean install for continuum previously so there is a sizable dependency in the repo to play with. 
> If you build with assembly 2.1, only the tarball is expanded and included in the final distribution (about 27mb) 
> With 2.2-beta-1, all the transitive dependencies are also expanded and included (about 65mb). 
> This is a functionality change, but also consumes a very large amount of memory and CPU.
