I can think of two ways to achieve this.

One way would be to get rid of the file and use only a hash or the
project manifest properties.

E.g.,

package(:jar).with :manifest=>{ 'Implementation-Title'=>'foo',
'Bundle-Version'=>VERSION_NUMBER }

OR

manifest['Implementation-Title'] = 'foo'
manifest['Bundle-Version'] = VERSION_NUMBER
package(:jar)

Another way would be to use a filter on your source file.

E.g.,

Your file src/main/resources/META-INF/MANIFEST.MF contains
Implementation-Title: foo
Bundle-Version: ${version}

Your buildfile contains
resources.filter.using 'version'=>VERSION_NUMBER
package(:jar).with :manifest=>_('target/resources/META-INF/MANIFEST.MF')

Cheers.
