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

[JacoboAdolfo]

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

@component(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

Can anybody help me? 

Thanks!

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.

[JacoboAdolfo]

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....

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

[JacoboAdolfo]

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.

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.

Please refer this https://www.linkedin.com/pulse/aem-project-setup-using-maven-archetype-26-64-keshav-chaurasiya/ and it was well described.

If you are planning to use specific archetype version such as 35 , then please refer relevant github link such as https://github.com/adobe/aem-project-archetype.

Here you will be getting properties details, recommended Java version , AEM version with their service pack details.

I believe if we create proper maven command after following all these documents then there won't be any issue.

[JacoboAdolfo]

Hi

Yes, I used archetype 35 because the training video suggests using the last version of the archetype. And the https://github.com/adobe/aem-project-archetype link is the one that I used to make my project. Once generated the project deploys well and keeps in "active" state but when I added a simple SlingServlet when deployed the problem with the dependencies appeared.

Now with the dependencies added when deployed gets an 'active' state.

Thanks.

[supriyo_sarkar]

I'm also facing exactly the same issue. Have you solved your issue? If so please guide me to do the same.

[saiprasadm]

Hi,

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

[JacoboAdolfo]

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.
