----------------------------------
Summary: Allow building of stacked ExecutionPlans
Key: JCRVLT-319
URL: https://issues.apache.org/jira/browse/JCRVLT-319
Project: Jackrabbit FileVault
Issue Type: Improvement
Components: Packaging
Reporter: Dominik Süß
The implementation of ExecutionPlanBuilder currently does not provide an option
to "pre-satisfy" dependencies when building but always checks for the install
state.
This comes with the following downsides:
* it is not possible to prebuild stacking execution plans that would be
satisfied/valid when executed in sequence - as soon as the validation is being
performed the second plan automatically spawns install tasks for the packages
missing
* The tasks for missing dependencies are automatically created with
PackageTask.Type.INSTALL even if all other tasks are EXTRACT tasks.
This improvement is about adding some kind of DependencyValidationHandler which
allows controlling how to handle a "missing" dependency (default behavior right
now is to check if already installed and add an install task if missing)
