If there are not any other errors in the log before these, that means 
buckminster
can not find the component in CVS.

You have requested a plugin with ID com.company.application and version 
0.0.0
in your CQUERY.

In order for buckminster to find it there must be a top level plugin 
project
in you cvs repository with exactly that directory name. The plugin has to
have the same ID _and_ its version has to be 0.0.0.

You can removed the "versionDesignator" attribute from your CQUERY, so
buckminster takes the latest version on the HEAD, AFAIK.

To identify a plugin (= bundle) I think buckminster at first tries to 
lookup
the META-INF/MANIFEST.MF file, where it can retrieve the bundle ID and 
version.
Maybe for 3.0 plugins it will get that information from plugin.xml?

The default for cvs is the HEAD. You can specify another branch or tag 
using
an advisor node in your CQUERY:

<cq:advisorNode namePattern="com.company.application" 
branchTagPath="THE_BRANCH_NAME"/>

In the RMAP you specify where your components are in the CVS repository.
 <rm:uri format=":pserver:mark@xxxxxxxxxx:/cvs,PATH_TO_COMPONENT/{0}">
   <bc:propertyRef key="buckminster.component" />
 </rm:uri>

Do not give up. A good resource is the buckminster repository itself.
