java.lang.NoClassDefFoundError com/adobe/aemfd/docmanager/source/DocumentSourceHandler

Hi

I am getting this error on trying to instantiate new Document.

I am using gradle with dependency com.adobe.aemfd:aemfd-client-sdk: 6.0.904

I don’t see this class in the jar either. Is there any other dependency I should add to resolve this issue?

Thanks!

    Hi, 

     

    The issue is saying the class DocumentSourceHandler is not available at runtime, usually this happens if you don’t have the proper bundles in place, please check your project’s bundle is activated at http://localhost:4502/system/console/bundles

     

    Please also check this issue here: 

     

     

    Hope this helps

      hi ​@ST99,

      it seems this issue has been adrressed in this thread: 

      They suggest to check the project dependencies against a brand new form project created with maven archetype.
