Niclas Hedhman commented on FELIX-899:
--------------------------------------
I disagree that BND should "guess" the Import package version ranges. I think
there is no "normal case". For you above, being a user of a.A has a very narrow
version range due to the subclassing, but in many use cases a much wider
version range are expected to work, and still yet for some projects even the
exact dot dot release are needed. Unless you know the policies of the project,
it is hard to predict a range that will actually work.
I think that there are some discussions going on in the OSGi community to
formalize the range expectations, but right now, with all the third-party stff
being bundlized, I think this feature will be more harming than helping.

> Key: FELIX-899
> URL: https://issues.apache.org/jira/browse/FELIX-899
> Project: Felix
> Issue Type: Bug
> Components: Maven Bundle Plugin
> Environment: Maven version: 2.0.9
> Java version: 1.6.0_11
> OS name: "linux" version: "2.6.25-gentoo-r7" arch: "amd64" Family: "unix"

> I have been using and testing out the
> maven-bundle-plugin-1.5.0-20081205.125536-1 (SNAPSHOT) and ran across what I
> believe is a bug.
> Suppose there is a project a:a:1.0.0-SNAPSHOT. This project has a single
> class: a.a.A. The bundle plugin has the following instructions:
> <instructions>
>
> <_versionpolicy>[$${version;===;$...@}},$${version;=+;$...@}})</_versionpolicy>
>
> <Bundle-RequiredExecutionEnvironment>JavaSE-1.6</Bundle-RequiredExecutionEnvironment>
>
> <Export-Package>$${replace;${Bundle-SymbolicName};\W;.}.*;version=${project.version}</Export-Package>
> </instructions>
> This results in an Export-Package line of:
> Export-Package: a.a;version="1.0.0.SNAPSHOT"
> So far so good. Now suppose there is a project b:b:1.0.0-SNAPSHOT. This
> project depends on a:a:1.0.0-SNAPSHOT (scope: provided) and the project also
> has a single class b.b.B which extends a.a.A. The maven-bundle-plugin is
> given the same instructions as project a:a above. The resulting
> Import-Package line is:
> Import-Package: a.a,b.b;version="[1.0.0,1.1)"
> This is not what is expected. What is expected is the following:
> Import-Package: a.a;version="[1.0.0,1.1)",b.b;version="[1.0.0,1.1)"
> Digging into the code I found that in
> org.apache.felix.bundleplugin.BundlePlugin (trunk rev: 723704) in function
> "protected Jar[] getClasspath( MavenProject currentProject ) throws
> ZipException, IOException" line 708 reads:
> final Collection artifacts = getSelectedDependencies(
> currentProject.getArtifacts() );
> When the plugin is running "currentProject.getArtifacts()" returns an empty
> set. This then causes the classpath not to be set properly when calling BND
> (none of the dependencies are available for reading their manifests). I
> changed the line to use "currentProject.getDependencyArtifacts()" and the
> manifest for b:b was correct.
> I am going to attach a file with two very simple projects which mirror what I
> have described here.
