ResourceFilterStream is always null after adapting from a resource

I followed this article to try to use Resource Filter Stream, project builds and deploys fine, however rfs is always null, any ideas?  Am I missing something?  Thanks in advance.

 

ResourceFilterStream rfs = resource.adaptTo(ResourceFilterStream.class);

Hi

 

This is an external bundle, so you need to wrap it into your bundle to deploy it along with your code. Please check this thread:

Hope this helps

@nelsonatensemble 

Can you verify if you have below dependency included in POM.xml and included the right imports for ResourceFilterStream

<dependency>
    <groupid>org.apache.sling</groupid>
    <artifactid>org.apache.sling.resource.filter</artifactid>
    <version>1.0.0</version>
    <scope>provided</scope>
</dependency>

Yes that was done, however, I did not embed the jar per h_kataria's comment below, so that's probably the issue.  I had assumed that the jar is available OOTB.

 

<embedded> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.resource.filter</artifactId> <target>/apps/<your-project>/application/install</target> </embedded>

As far as I know, resourcefilterstream is not available OOB, so you will have to embed it in your all pom.xml in filevault-package-maven-plugin config section

<embedded> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.resource.filter</artifactId> <target>/apps/<your-project>/application/install</target> </embedded>

 and add the dependency

<dependency> <groupId>org.apache.sling</groupId> <artifactId>org.apache.sling.resource.filter</artifactId> <version>1.0.0</version> <scope>provided</scope> </dependency>

    Ah maybe that's it, I added the dependency but i did not embed the bundle, I will give that a try.  Thanks all.

    add this in core bundle pom as well as embed it in all pom

    <bnd><![CDATA[
    Import-Package: javax.annotation;version=0.0.0,*
    Export-Package: com.mysie.*
    -plugin org.apache.sling.caconfig.bndplugin.ConfigurationClassScannerPlugin,org.apache.sling.bnd.models.ModelsScannerPlugin
    -includeresource: org.apache.sling.resource.filter-1.0.0.jar;lib:=true

      the solution is missing this step 

      <bnd><![CDATA[
      Import-Package: javax.annotation;version=0.0.0,*
      Export-Package: com.mysite.*
      -plugin org.apache.sling.caconfig.bndplugin.ConfigurationClassScannerPlugin,org.apache.sling.bnd.models.ModelsScannerPlugin
      -includeresource: org.apache.sling.resource.filter-1.0.0.jar;lib:=true
