sling context aware configuration context-aware-confi...

[srikanthg212933]

Hi Everyone,

I am trying to use sling context aware configurations inside AEM 6.5 project to store some configurations.

As described here https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configurati...

I have tried adding bnd statement with below plugin

org.apache.sling.caconfig.bndplugin.ConfigurationClassScannerPlugin

 But still my bundle is not able to identify configuration files (annotated with @Configuration) after deploying it into OSGI.

And If i manually add like below then only it started identifying 

Sling-ContextAware-Configuration-Classes:com.abc.caconfigs.MySampleConfig

 Could you guys please let me know how can we do it without adding each class names and should make it work with only plugin? .

I have a working example at https://github.com/joerghoh/cqdump/tree/master/ca-config-example which also includes the mentioned plugin.

The maven-bundle-plugin is configured here: https://github.com/joerghoh/cqdump/blob/master/ca-config-example/core/pom.xml

// Update: I do use the maven-bundle-plugin and not the bnd-maven-plugin.

Hi, I have seen you added Maven-bnd-plugin. Instead why Can't I achieve this with bnd-maven-plugin as described here https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configurati...

[Jörg_Hoh]

As far as I can see both my pom.xml and the referenced documentation use the maven-bundle-plugin.

Did you tried below ?

<plugin>
				<groupId>biz.aQute.bnd</groupId>
				<artifactId>bnd-maven-plugin</artifactId>
<configuration>
					<bnd><![CDATA[
						-plugin org.apache.sling.caconfig.bndplugin.ConfigurationClassScannerPlugin
                                ]]></bnd>
				</configuration>
				<executions>
					<execution>
						<id>bnd-process</id>
						<goals>
							<goal>bnd-process</goal>
						</goals>
						<configuration>
							<bnd><![CDATA[
						Bundle-Category: MyApp
						Sling-Model-Packages: com.aem.core.models
						-snapshot: ${tstamp;yyyyMMddHHmmssSSS}
						Bundle-DocURL:
                                ]]></bnd>
						</configuration>
					</execution>
				</executions>
			</plugin>

The below works for me.

            <plugin>
                <groupId>biz.aQute.bnd</groupId>
                <artifactId>bnd-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>bnd-process</id>
                        <goals>
                            <goal>bnd-process</goal>
                        </goals>
                        <configuration>
                            <bnd><![CDATA[
						Bundle-Category: MyApp	
						Sling-Model-Packages: com.aem.core.models
						-snapshot: ${tstamp;yyyyMMddHHmmssSSS}
						Bundle-DocURL:
-plugin org.apache.sling.caconfig.bndplugin.ConfigurationClassScannerPlugin
                                ]]></bnd>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

Hi @Shakir 

Just make sure you are including ModelScanner as well for Sling Model

e.g. https://github.com/arunpatidar02/aemaacs-aemlab/blob/f96ce5316dfa4798c72d2e87d3a0b41fc49791a4/pom.xm...

[Eason_Pai]

Its not working even though instructions in sling doc are followed, but i figured it out that you need to manually append this line to the bnd-process before the actual ConfigurationClassScannerPlugin in plugin bnd-maven-plugin

Sling-ContextAware-Configuration-Classes: 

Then you generated required headers in the MENIFEST file. At this moment i cannot tell you why, but it works for me.

[Jörg_Hoh]

I hope, that the order does not matter. But if the documentation is not accurate anymore and the plugin does not work correctly, I would recommend to discuss this at the Sling lists.
