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

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>

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
