It depends. One important bit boils down to what level of 'accuracy'
you wish to have in your OSGi Manifest. I have found from experience
that it is unwise to try to have algorithmic resolution of the Imports
and Exports, and instead it is better to maintain it manually, but
have BND report 'missing' and 'superfluous' references.
In my multi-module build, where a large number of plugins follows a
naming convention, I have ended up with;
Top level;
jar {
manifest {
license = 'http://www.apache.org/licenses/LICENSE-2.0.txt'
docURL = 'http://www.qi4j.org'
description = 'Qi4j is a platform for Composite Oriented Programming'
vendor = 'Qi4j Community, http://www.qi4j.org'
}
}
Each Project;
jar {
manifest {
name = "Qi4j Core Runtime"
instruction 'Private-Package',
'org.qi4j.runtime;version=' + version,
'org.qi4j.runtime.bootstrap;version=' + version,
'org.qi4j.runtime.composite;version=' + version
instruction 'Import-Package',
'org.qi4j.api.composite;version=' + version
:
(and applying the 'osgi' plugin)
Now, if you care less, then you can instruct BND to "import all I
might need" and "export all I have", which will give you something
that is likely to work, but not necessarily appreciated by your
users... For instance; upstream dependencies won't have good version
ranges.
