I’m working on a task consisting of creating a plain Liferay module to override an OSGi component of the module ‘com.liferay.document.library.web’ (specifically, the component ‘com.liferay.document.library.web.internal.portlet.toolbar.contributorDefaultDLPortletToolbarContributor’). The overriding component has a reference to a component that resides in the module ‘com.liferay.document.library.web’:

@Reference
private DLPortletToolbarContributorHelper _dlPortletToolbarContributorHelper;

As a consequence, I’ve included the following dependency in my ‘pom.xml’ file:

<dependency>
    <groupId>com.liferay</groupId>
    <artifactId>com.liferay.document.library.web</artifactId>
    <scope>compile</scope>
</dependency>

Everything is ok during compiling and building stages, but when deploying the module’s jar file, I’m getting this error:

ERROR [fileinstall-F:/liferay/osgi/modules][LogService:93] Error while starting bundle: file:/F:/liferay/osgi/modules/my-module.jar

org.osgi.framework.BundleException: Could not resolve module: my-module [1070]_  Unresolved requirement: Import-Package: com.liferay.document.library.web.internal.portlet.toolbar.contributor.helper_ [Sanitized]

I’ve tried including the following directive in the my-module’s ‘bnd.bnd’ file, but I didn’t get rid of the previous error:

Import-Package: com.liferay.document.library.web.internal.portlet.toolbar.contributor.helper

Yet, I’ve tried the proposals suggested in this post, but it didn’t succeed.

I might be wrong, but my reasoning is that ‘my-module’ requires a package (the one stated in the ‘Import-Package’ directive), and thus, the target module should export that package. However, the target package resides in the module ‘com.liferay.document.library.web’, which is a Liferay module whose ‘bnd.bnd’ file I can't handle.

I’d really appreciate if someone could clarify what’s going on, and how I should proceed to get rid of the problem that is making the overriding module not be deployed successfully.

Thanks.
