Re: cayenne-maven-plugin and its executions environment

[Andrus Adamchik <an...@objectstyle.org>]

Hi Maria,

This may be just a typo in your POM:

> <map>${project.basedir}/src/main/resources/scenario/my.map.xml</map>

vs

>  <map>${project.basedir}/src/main/resources/my.map.xml</map>


("scenario" folder is missing in the last case)

As an aside, since 4.1 CayenneModeler started to save your class generation settings in .map.xml in a portable way, so our default advice became to use CayenneModeler instead of Maven cgen for class generation. (But of course you can keep using Maven if that better fits your workflow).
