Need help in implementing Sling Context Aware Configuration

Hi,

I am looking to use Sling Context Aware Configuration.
https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configuration.html

I have added these in the POM file
<dependency>
            <groupId>org.apache.sling</groupId>
            <artifactId>org.apache.sling.caconfig.impl</artifactId>
            <version>1.0.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.sling</groupId>
            <artifactId>org.apache.sling.caconfig.api</artifactId>
            <version>1.0.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.sling</groupId>
            <artifactId>org.apache.sling.caconfig.spi</artifactId>
            <version>1.0.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.sling</groupId>
            <artifactId>org.apache.sling.caconfig.bnd-plugin</artifactId>
            <version>1.0.0</version>
        </dependency>


Java code
ResourceResolver resourceResolver = request.getResourceResolver();
Resource contentResource = (Resource) resourceResolver.getResource("/content/ubi/test");
ValueMap props = contentResource.adaptTo(ConfigurationBuilder.class).asValueMap();
String param1 = props.get("param1", String.class);

Issue:
ConfigurationBuilder Class is not getting resolved.

Am I missing something?  Any help is appreciated..

Gopal

Posted by Stefan Seifert <ss...@pro-vision.de>.
you do not need org.apache.sling.caconfig.bnd-plugin as direct reference in your - it's only useful as dependency for maven-bundle-plugin or other tooling that used bnd to generate the OSGi SCR metadata, see [1] as an example.

but this should not be the source of your problem - did you deploy the bundles org.apache.sling.caconfig.impl, org.apache.sling.caconfig.api, org.apache.sling.caconfig.spi to your application instance, and are they running (check OSGi console)?

if yes, can you give us the full stack trace?
