Steps to reproduce

pom.xml
codegen-module/pom.xml
codegen-module/src/main/resources/api.yml

if I build codegen-module standalone, it works
if I build the multi-module project, it fails saying

'src/main/resources/api.yml not found

Suggest a Fix

The maven plugin 'CodeGenMojo' should check whether the path given in inputSpec is relative or absolute.
It should prefix relative paths it with the value of maven variable ${project.basedir}.

Start with the CodeGenMojo entry point and the pom.xml files named in the report. Reproduce the difference between standalone and reactor builds using codegen-module/src/main/resources/api.yml, then inspect how the relative inputSpec is resolved. Done means the relative path works in both build modes without requiring ${project.basedir}.
