---------------------------------------
Summary: Provide mechanism to install several packages at once
Key: JCRVLT-190
URL: https://issues.apache.org/jira/browse/JCRVLT-190
Project: Jackrabbit FileVault
Issue Type: Improvement
Components: Packaging
Reporter: Tobias Bocanegra
it should be possible to install several packages at once. the package manager
has ensure the correct installation order based on dependency resolution. the
installation operation should be divided into a prepare and execute phase. the
preparation phase will generate a _InstallationPlan_ which is serializable. The
execution phase will use the _InstallationPlan_ and operate on the packages
accordingly. the separation of prepare and execute has the advantage, that the
preparation can already validate the correctness and optimize the import order.
draft proposal:
{code}
InstallationPlanBuilder PackageManager.getInstallationPlanBuilder();
InstallationPlanBuilder.installPackage(PackageId);
InstallationPlanBuilder.uninstallPackage(PackageId); // probably not needed
right now
InstallationPlan InstallationPlanBuilder.build();
InstallationPlanBuilder.load(InputStream)
InstallationPlan.save(InputStream)
InstallationPan.validate();
InstallationResult PackageManager.execute(InstallationPlan);
{code}
