I tried to get some services from the DefaultMetaDataResolver class. Since i
dont have following objects it is throwing nul pointer exceptions.
* private MetadataRepository metadataRepository;
* private StorageMetadataResolver storageResolver;
stack trace :
java.lang.NullPointerException
at
org.apache.archiva.metadata.repository.DefaultMetadataResolver.getRootNamespaces(DefaultMetadataResolver.java:122)
As deng mentioned those objects are injected by plexes by the
@plexus.requirement annotation. But here that annotation is commented. But
in components.xml i saw those objects as reqiurements.
Here actually I want to know how do we inject those objects when we are
using that DefaultMetadataResolver class in another module.?
thankz.
