]
Dennis Lundberg updated MASSEMBLY-445:
--------------------------------------
Component/s: component descriptor
Description:
Please support parametrization of component descriptors. One should be able to
specify parameter placeholders in component descriptors, and when referencing
component descriptor from an assembly descriptor provide actual parameter
value(s) which would then be applied to the parameter placeholders. One should
be able to set global parameters (for all component descriptors), and component
descriptor specific parameters, with component descriptor specific parameters
overriding global ones if their names overlap.
This would be useful if e.g. one uses assembly descriptors to specify
assemblies for different deployment environments, and if these assemblies
differ (see example [1]) only in which environment specific configuration file
should be included in the assembly where this distinction is based on
configuration file name suffix - this suffix could be passed to shared
component descriptor as parameter, like in example [2].
