Hi,

I have built a custom AEM component 'Byline' by following AEM WKND tutorial. However, after deployment, I am not able to find my component model in AEM web console for Sling models. I am using AEM 6.4 quickstart, getting following errors while using this component:

Caused by: org.apache.sling.scripting.sightly.SightlyException: Compilation errors in org/apache/sling/scripting/sightly/apps/wknd/components/content/byline/byline_html.java:

Line 28, column 1272 : Only a type can be imported. com.adobe.aem.guides.wknd.core.components.Byline resolves to a package

Also, I can see following error while viewing my site OSGi bundle in AEM Web console:

com.adobe.cq.wcm.core.components.models,version=[12.5,13) -- Cannot be resolved

I am not sure if I am missing any configuration or mvn dependency. Can I please get some help to resolve these errors?

Thanks for replying. It seems the tutorial was recently updated to use Core components 2.2.0 and I was using Core components 2.0.4 for models as required earlier. I have updated the configurations accordingly which has resolved all errors.

What is the version of AEM you are using? . Make sure the below prerequisites are met

The following is required:

Hi Veena,

Thanks for replying!

I am using AEM 6.4.2.0. I have all per-requisites installed and have already followed all steps for project setup described in Chapter 1 and have been following all steps in subsequent chapters as well. I am not sure why I am still getting this error, I don't see anything described in the tutorial missing from my configurations. Do you have any other pointers to proceed?

I am getting similar errors in creating any other model component as well. I am stuck with these errors for so long now and would really appreciate getting some help to resolve them.

Thanks,

Khushboo
