Compass Mapping XML
To use Compass Mapping XML, add a
DomainClassName.cpm.xml file to your classpath.
Normally with Compass you need a master XML config file - typically
compass.cfg.xml - in which you declare these mapped classes. With the Searchable Plugin you can choose whether you want a @compass.cfg.xml@; if it is not found, it detects your mapping XML files automatically.
Refer to the Compass docs
from here for more.
The plugin currently configures the Compass mappings by generating this XML at runtime, so if you would like to see it, enable debug logging.
