AEM bundle not starting

Hi,

my AEM bundle is not starting on local due to "org.apache.sling.servlets.annotations -- Cannot be resolved".
I can't find any bundle exporting "org.apache.sling.servlets.annotations". The package is needed for using SlingServletFilter.

I wonder what I might miss because it was already running like 2 months ago and I haven't done any changes. I even installed the latest AEM SDK but still the same error.
Can you help please, how that missing bundle/package could be added?

Thanks,
Peter

Hi,

This is supported with R7 


https://sling.apache.org/documentation/the-sling-engine/servlets.html#registering-a-servlet-using-java-annotations-1

 

you may need to check the bnd plugin 

https://github.com/arunpatidar02/aemaacs-aemlab/blob/e31fc62bfd147e56ecaca740c6e2739c66c75f75/core/pom.xml#L23

 


here is the servlet status

 

 


Thanks @arunpatidar , i finally found the root cause, it seems.

bnd-maven-plugin gave this warning:
[INFO] --- bnd-maven-plugin:6.4.0:bnd-process (bnd-process) @ wknd-spa-react.core ---
[WARNING] /.../core/pom.xml [0:0]: No translation found for macro: componentGroupName

After i have set the componentGroupName property (seems like both empty value or adobe works), my deployed bundle is starting without missing package. I don't see what i had different in the past, because it used to work. 
Anyway, thanks for the help.

Regards,
Peter

@pnagy 

Use AEM Dependency Manager and get the version and then place that dependency into the projects POM in the dependency section.  http://localhost:4502/system/console/depfinder

    The package is not exposed by any bundles:

      @pnagy Try to set the below dependency in your main pom.xml with version and build/deploy and see if it fixes.

      <dependency>
          <groupId>org.apache.sling</groupId>
          <artifactId>org.apache.sling.servlets.annotations</artifactId>
          <version>1.2.6</version>
          <scope>provided</scope>
      </dependency>

        I do have the dependency added in the project with provided scope, but it's not provided on AEM:

          Hi @pnagy 
          I am using import org.apache.sling.servlets.annotations.SlingServletResourceTypes; in AEMaaCS Sdk without an error

            Hi @arunpatidar ,

            can you say which bundle does expose the package org.apache.sling.servlets.annotations by searching it at http://localhost:4502/system/console/depfinder or http://localhost:4502/system/console/bundles ?
