Jeremy Boynes commented on GERONIMO-504:
----------------------------------------

I can see merit in validating during deployment as it would avoid the possibility of ClassNotFoundExceptions as we try to create GBean instances. However, this means that all dependencies would need to be present during deployment whereas in reality they may not actually be needed to deploy the module - for example, dependencies could be used to make classes available for application use (e.g. struts) but we would not need those to actually create the target configuration.

Regardless of whether we check during deployment, the possibility of missing dependencies will always exist at configuration start time. For example, someone could have removed the dependency from the target server after the configuration had been installed.

Given this, I would suggest we fix this by checking dependencies during normal deployment but that we also add an option to the deployer that would allow this check to be disabled.

> <dependency> elements defined by the various deployment plans are not validated. It is possible to deploy successfully plans defining dependencies, which are not defined by the installed repositories.
> When such configurations are started, the Kernel throws as expected a MissingDependencyException identifying the missing dependency.
> This should be done upfront during deployment.
