Use MANIFEST.MF resident build number/timestamp in PAM instead of computing checksums for deployment
version
------------------------------------------------------------------------------------------------------------

                 Key: JS2-982
                 URL: https://issues.apache.org/jira/browse/JS2-982
             Project: Jetspeed 2
          Issue Type: Improvement
    Affects Versions: 2.1.4, 2.2.0
         Environment: Maven builds
Jetspeed V[PAM], (PortletApplicationManager)
            Reporter: Randy Watler
            Assignee: Randy Watler
            Priority: Minor


Computing checksums of portlet.xml, jetspeed-portlet.xml and web.xml to determine version
of portlet application is not viable in some containers that rewrite these files. Adding a
build number and/or timestamp field in the portlet application war MANIFEST.MF file may provide
a stable analog.

This feature could be used to unify VPAM and PAM implementations. Note that VPAM uses a pa_version
field in jetspeed-portlet.xml to determine version; this option/mode must be preserved for
more stable production environment. The proposed build number/timestamp implementation is
well suited for a development or automated environment since every new version of a portlet
app will be [re]registered.

See the buildnumber-maven-plugin for implementation.
