Felix scr annotations are not working in aem 6.2

[krishc76025392]

Hi,

we migrated from cq 5.6.1 to AEM 6.2 and observed that few services are not working in AEM 6.2.

@component and @service annotations are not making our class registered as component and service in felix-->OSGI--->Services.

The dependencies in our POM is as below:

<dependency>

<groupId>org.apache.felix</groupId>

<artifactId>org.apache.felix.scr.annotations</artifactId>

<version>1.9.0</version>

<scope>provided</scope>

</dependency>

Does anybody know why it happened and how to fix it?

Hi,

One use case I faced in Aem 6.2 is if any of the classes is using annotations from package 'org.osgi.service.component.annotations', annotations of package 'org.apache.felix.scr' are ignored by Aem.

So, you can take a look at the codebase if any class is using annotation from 'org.osgi'  annotation package.

Indeed, can you share the imports too from your class.

I dont think, all changes are needed. Just 2 dependency versions need to be updated.. Here is a blog that talks about similar issue: Issues while Migrating from Java6 to Java8 in AEM 6.1 | TO THE NEW Blog
