== Nested external resources ==

Resources can now be injected into other resources. 

{{{
AnalysisEngineDescription descriptor = AnalysisEngineFactory.createPrimitiveDescription(
  TestAnalysisEngine2.class,
  TestAnalysisEngine2.PARAM_RESOURCE, createExternalResourceDescription(
    TestExternalResource2.class,
    TestExternalResource2.PARAMETER, "value",
    TestExternalResource2.PARAM_RESOURCE, createExternalResourceDescription(
      TestExternalResource.class,
      TestExternalResource.PARAMETER, "value")));
}}}

Nested resources are only initialized if they are used in a pipeline which contains at least one component that calls  `ConfigurationParameterInitializer.initialize()`. Any component extending uimaFIT's component base classes qualifies. If you use nested resources in a pipeline without any uimaFIT-aware components, you can just add uimaFIT's `NoopAnnotator` to the pipeline.
