Read properties from properties source

Hi Pascal,

Is it conceivable for you that some of the properties are read in via any sources? 

By the way:
At this second I don't know about maven extensions, but shouldn't maven complain about placeholders? `'version' contains an expression but should be a constant. @ com.acceo.stuff.abc:stuff-abc-parent:${MYPROJECT_VERSION}`

Thanks
Torsten
