I have com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider 2.10.0 installed in an OSGi environment without com.fasterxml.jackson.module.jackson-module-jaxb-annotations installed since it is optional for OSGi environments. However, when I declare com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider as a dependency in my Maven project, the org.apache.felix:maven-bundle-plugin generates the Import-Package section of my MANIFEST.MF for my project's bundle as, in part:

javax.xml.bind;version="[2.3,3)",javax.xml.bind.annotation;version="[2.3,3)"

Which is a problem for me since my OSGi environment only provides javax.xml.bind 2.1.0. This prevents my bundle from starting. I can work around this by excluding com.fasterxml.jackson.module:jackson-module-jaxb-annotations in my pom:

<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
    <version>2.10.0</version>
    <scope>provided</scope>
    <exclusions>
        <exclusion>
            <groupId>com.fasterxml.jackson.module</groupId>
            <artifactId>jackson-module-jaxb-annotations</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Which then causes the Import-Package part of my MANIFEST.MF to be written as:

javax.xml.bind,javax.xml.bind.annotation

which works with my OSGi environment.

An alternative to me excluding com.fasterxml.jackson.module:jackson-module-jaxb-annotations from my dependency decleration would be having com.fasterxml.jackson.module:jackson-module-jaxb-annotations marked as an optional dependency in the com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider project. When that is the case I get the same result in my Import-Package as I get when I explicitly exclude com.fasterxml.jackson.module:jackson-module-jaxb-annotations.

I'm unsure if there is a reason com.fasterxml.jackson.module.jaxb is marked as optional in the osgi section of the pom, while the com.fasterxml.jackson.module:jackson-module-jaxb-annotations dependency is not also marked as optional.
