If your Sling Models are not working.....

You need to have:

org.apache.sling.models.api.1-1.0.jar installed in the OSGI console, system/console/bundles. Before doing extensive troubleshooting, be sure this bundle is installed. The error might look something like this:

Failed installing bundle : Unable to install/update bundle from dir C:\Users : Unresolved constraint in bundle com.adobe.training.dc.core [393]: Unable to resolve 393.0: missing requirement [393.0] osgi.wiring.package; (&(osgi.wiring.package=org.apache.sling.models.annotations)(version>=1.1.0)(!(version>=2.0.0)))

Unable to install/update bundle from dir C:\Users: Unresolved constraint in bundle com.adobe.training.dc.core [393]: Unable to resolve 393.0: missing requirement [393.0] osgi.wiring.package; (&(osgi.wiring.package=org.apache.sling.models.annotations)(version>=1.1.0)(!(version>=2.0.0)))

Also, do not forget to delete the old bundle that wasn't working from system/console/bundles

To resolve the issue:

  1. Install the missing bundle: Ensure org.apache.sling.models.api version 1.1.0+ is installed in AEM via the OSGi console (/system/console/bundles).
  2. Update bundle version: If already installed, ensure it’s version 1.1.0 or higher.
  3. Reinstall affected bundle: Reinstall the com.adobe.training.dc.core bundle after the dependency is resolved.
  4. Restart AEM: Restart AEM to apply the changes.

This should fix the unresolved dependency error.

what if you have WCMUSEPOJO working but not the sling models as sling models-->@postconstruct method not at all being called form the HTL component in AEM 6.3 .

Any clue ?
