> Project: UIMA
> Issue Type: Improvement

> Affects Versions: 2.2.2
> Reporter: Marshall Schor
> Assignee: Marshall Schor

>
> The maven system allows refactoring things using an inheritance tree. We use
> this capability via a hierarchy starting with uimaj project's POM. We also
> have a "flat" layout for subprojects, following Eclipse conventions.
> When running maven on a component, say, uimaj-ep-configurator, its POM has a
> parent POM. This parent is "looked up" using the maven system of identifying
> artifacts, in the maven repository chain, starting with the local repository.
> This means that if you change any of the super POMs in the chain, those
> changes are *ignored* until you do a "mvn install" on those POMs.
> The work-around was to do a "mvn -N install" in the directory where the
> changed POM was. The -N flag says just do the install on the POM, and skip
> any sub-processing of the aggregated "modules" (if any) that the POM
> specified using the <modules> element.
> Recently, while trying to improve the maven builds, I (again) forgot this
> fact, and wondered why my changes to the superPom were not having any effect.
>
> To overcome this (for future maintainers so they won't suffer from this), add
> an optional <relativePath> element to the <parent> element of all the POMs in
> the uimaj and uimaj-as projects. (Perhaps this should also be done, at some
> point, for the other projects too, but that can be another Jira).
> The <relativePath> is a relative path to the directory containing the parent
> POM, and will be tried first before looking up the POM in the repositories.
