> Enhance the Maven Deploy Plugin to support Flat POM
> ---------------------------------------------------
>
> Key: MDEPLOY-173
> URL: https://issues.apache.org/jira/browse/MDEPLOY-173
> Project: Maven Deploy Plugin
> Issue Type: New Feature
> Components: deploy:deploy
> Reporter: Jack Jia
> Assignee: Robert Scholte
>
> *Problem*
> The pom.xml has dual purpose.
> 1. Building and distributing a jar
> 2. Used by another project for dependency management.
> For #1 build and distribution, pom.xml makes good sense with many sections
> and hierarchies. In this case the main objective is dealing with sources and
> various aspects of build.
> For #2, lets say project B needs the jar produced by project A ( #1), the
> only things B needs from A are,
> 1. jar files
> 2. dependencies of this jar file
> For #2 use-case, none of the sections or hierarchies of pom.xml make sense,
> except for <dependencies>.sections and GAV.
> Unfortunately maven simply copies the same pom.xml used for build to the
> repository for distribution.
> This problem gets complicated when there are pom hierarchies and
> <dependencyManagement> sections
> In such cases, to resolve the dependencies of an artifact, maven needs to use
> more than one pom.xml. This results in complex release and patch process and
> potential build time issues.
> *Solution*
> Enhance the maven deploy plugin to deploy a "flattened" pom that contains
> only GAV and <dependencies> section.
> The <dependencies> section contains, properly resolved direct dependencies of
> the artifact, which are the same of "pom hierarchy" direct dependencies.
> "flattened" pom means it cannot have any parent or any other sections that
> are not necessary while deploying the artifact.
> Note that we may need to add removeMetadata method to
> org.apache.maven.artifact.Artifact interface to remove the original pom
> metadata and then add the "flattened" pom metadata. I have created jira issue
> http://jira.codehaus.org/browse/MNG-5544 for this function
> *Acceptance Criteria*
> 1. "mvn deploy" could deploy "flatten" pom onto maven repo and its "flatten"
> pom's dependencies version should be the same as versions of "pom hierachy".
> 2. "flatten" pom only contains GAV and <dependencies> section.
> 3. "flatten" pom only contains original direct dependencies, not including
> transitive dependencies.
> 4. "flatten" pom won't inherit from any parent pom.
> 5. "flatten" pom is only for artifact whose packaging is jar.
