WKND tutorial core components package not compatible with AEM 6.5

Question

I used the latest archetype for the WKND component (version=35).

This uses newer version of wcm.components.core (2.17.12), unlike my AEM instance which uses lower version of wcm.components.core (2.3.2).

When, generating and installing with maven, there is an error for the api bundle: com.day.cq.wcm.api,version=[1.28,2) -- Cannot be resolved

From here, the "en.html" page is empty and no components are available to insert. This is because of another error which states:

com.adobe.cq.wcm.core.components.models.Page cannot be resolved to a type

Does anyone have a solution to this?

Hi @ginovski, to solve the issue you need to pick up one of below solutions:

Upgrade your AEM instance by installing Service Pack 7 or higher, this is according to system requirements for archetype version 35 - https://github.com/adobe/aem-project-archetype#system-requirements
You can download service packs from software distribution service https://experience.adobe.com/#/downloads/content/software-distribution/en/aem.html
Generate your project using older version of archetype, you can find detailed compatibility matrix that is presenting which archetype version supports which AEM version under this link https://github.com/adobe/aem-project-archetype/blob/develop/VERSIONS.md
Last option is to manually change version of core components you are using in your project according to following document https://experienceleague.adobe.com/docs/experience-manager-core-components/using/versions.html?lang=en#release-history-requirements, please keep in mind that changing the version number could not be enough and maybe you will need to align version of other dependencies as well.
