local provider never seems to resolve components [message #654696]

I'm attempting to use the local provider in my rmap to resolve various components that have already been checked out into my workspace directory (although not registered as projects). It typically fails like this:

uk.ac.gda.nexus:osgi.bundle: Trying provider local(file://{0}/plugins/{1}[file:///scratch/xx/plugins/uk.ac.gda.nexus])
uk.ac.gda.nexus:osgi.bundle: Found match 
uk.ac.gda.nexus:osgi.bundle: Using provider local(file://{0}/plugins/{1}[file:///scratch/xx/plugins/uk.ac.gda.nexus])
uk.ac.gda.nexus:osgi.bundle: Resolution attempt ended with exception: Provider local(file:///scratch/xx/plugins/uk.ac.gda.nexus): Missing CSpec source required by component type osgi.bundle

In this case, the directory file:///scratch/xx/plugins/uk.ac.gda.nexus actually exists, and contains the correct content, with no permissions problems.

This is the type of entry in my rmap:

    <rm:provider componentTypes="osgi.bundle" resolutionFilter="(try_local_provider=yes)" readerType="local">
      <rm:uri format="file://{0}/plugins/{1}">
        <bc:propertyRef key="workspace.root"/>
        <bc:propertyRef key="buckminster.component"/>
      </rm:uri>
    </rm:provider>
    <rm:provider componentTypes="osgi.bundle" readerType="svn">
      <rm:uri format="${GDA_subversion}/${GDA_branch}/plugins/{0}">
        <bc:propertyRef key="buckminster.component"/>
      </rm:uri>
    </rm:provider>

It always fails and falls through to the svn provider. This happens for every component type. What am I doing wrong?
Thanks

Hi Matthew,

please note that if you have several providers in a searchPath, the resolver never "falls through". It will always
consult *all* providers listed and then select the best version found. If you want to do a "fall through", then you must
have several <locator ... failOnError="false"/> in the rmap that appoints different searchPaths.

Thanks. The problem turned out to be an error in a script file - I was actually deleting my local copy, so of course it was not found by the provider.

The message Missing CSpec source indicates just that.
