AEM 6.5 - New Project with a Servlet - Dependencies not resolved

Hi community!

 

I'm entering on the AEM world by following the Adobe Tutorials. I'm with Servlets right now and I found a stopper and after searching in google for hours I don´t know how to go on... these are the steps I followed.

 

1) new project

mvn -B archetype:generate -Padobe-public -D archetypeGroupId=com.adobe.aem -D archetypeArtifactId=aem-project-archetype -D archetypeVersion=23 -D appTitle="ProyectoFormacionv2" -D appId="trainingProjv2" -D groupId="com.adobe.aem.training.projectv2" -D artifactId="aem-training-project-v2" -D version="0.0.1-SNAPSHOT"

 

2) add new servlet on the core project

@8220494(service=Servlet.class,
property={
Constants.SERVICE_DESCRIPTION + "=Servlet to Render Product Data",
"sling.servlet.methods=" + HttpConstants.METHOD_GET,
"sling.servlet.paths="+ "/bin/productData"
})
public class ResourceToJSONServlet extends SlingSafeMethodsServlet {

...

 

3) run clean install autoInstallPackage adobe-public

In the pom.xml file of the core project I don't see the dependencies of your image, these are the dependencies of my core/pom.xml:

I did not add any dependency because in the adobe training video the instructor did not add any, but the instructor used archetype 14.

 

Do I have to add dependencies? which ones? 

 

Maybe the maven instruction to create the project is wrong? 

 

Thanks for you support.


At least I added several dependencies to the core project:

I got these dependencies from another project. Now all is OK and the servlet works nice.

 

The tutorial from Adobe video training was very confusing, there is no reference to add these dependencies.

 

Thanks for the provided help.

 

Regards.

Hi @jacoboadolfo ,

This comes because your dependencies are not getting resolved.

 

Can you help me with following details :
1. AEM version being used 

1a. Any service packs installed 
2. mvn archetype version used 

3. What is the scope defined as for the maven project 


you can also check dependencies using dependency finder :
 http://<host>:<port>/system/console/depfinder


Thanks.

    1. AEM 6.5

    1a. > http://localhost:4502/system/console/productinfo

    Installed Products: Adobe Experience Manager (6.5.0)

    I don´t see anything related with service packs.

     

    I made the project using mvn command:

    mvn -B archetype:generate -Padobe-public -D archetypeGroupId=com.adobe.aem -D archetypeArtifactId=aem-project-archetype -D archetypeVersion=35 -D appTitle="ProyectoFormacionv1" -D appId="trainingProjv1" -D groupId="com.adobe.aem.training.projectv1" -D artifactId="aem-training-project-v1" -D version="0.0.1-SNAPSHOT"

     

    archetypeVersion=35

     

    Sorry, but I don´t understand what are requesting me at point 3 "What is the scope defined as for the maven project".

     

    Thanks for your help.

      Here is the info associated with scope https://howtodoinjava.com/maven/maven-dependency-scopes/#:~:text=Maven%20provides%20six%20scopes%20i.e.,test%20%2C%20system%20%2C%20and%20import%20.

       

      In pom.xml file you will be getting scope information like the below one -

        Hi,

         

        I am also facing the same issue. Any resolution for the above issue?

        I fixed it by upgrading my AEM 6.5 local instance to the lastest AEM Service Pack. Once installed, in the bundle manager page I started the bundle and it started properly.

         

        Good luck, thanks.
