Add VPF as a reort output feature
---------------------------------
Key: IVY-897
URL: https://issues.apache.org/jira/browse/IVY-897
Project: Ivy
Issue Type: New Feature
Components: Core
Affects Versions: 2.0.0-beta-1
Reporter: Nascif Abousalh-Neto
Priority: Minor
Fix For: unspecified
One of the best practices in the use of Ivy for large organizations is to
replace all the revision values in the ivy.xml files with properties.
<dependency name="my.module" revision="${my.module.revision}" ... />
This approach allows an administrator to control all revisions values used by
all modules in one single place - a Version Property File (or VPF for short).
This way versions can be controlled in a uniform way, with minimum maintenance
and reduced chance of error. For example, you can upgrade all your modules
dependencies from Log4J 3.5 to 4.0 with one single line change - and be sure
that you didn't forget any of them behind.
Creating and maintaining VPFs is not trival though. One way to automate the
process is to "harvest" the module names and their latest versions from the
repository, using the repreport task to create a resolution report for the
entire repo and then converting it to a property file format using a XSL
spreadsheet (attached).
