You can't use ${project.build.*} expressions in the <build> section
under some circumstances. I tested with project.build.directory and
project.build.outputDirectory (even in a <resource><directory> section) -
you might even get recursion
when specifying <build><directory>${project.build.directory} :)
${project.version} works though.
I think this is a bug but I'm not sure if this can/will be fixed..
Officially you should only be able to use such an expression after
the tag in the <build> section you refer to is itself
interpolated/resolved.
For instance, in the <build> section the resources are specified first,
then the directory (target/), then finalName etc.
If you use the value of the <build><directory> before it's defined (like
in a resources section), it should fail. Although sourceDirectory is
specified afterwards, so it _should_ work (but doesn't).
The interpolation process is not done in this order though, and I'm not
sure why ${project.build.*} doesn't work and ${project.version} does.
There's some room for improvement here.
