Unable to load wknd project and core components with latest AEM and Project Archetype

[rohitya2]

Hello everyone,

I am new to the AEM ecosystem and have recently attempted to install AEM quick start with author and publish environments. Everything appears to be working fine and I am able to view the retail site.

I am currently following this link

https://experienceleague.adobe.com/docs/experience-manager-learn/getting-started-wknd-tutorial-devel... to set up my project. However, after generating AEM for the wknd project, I am encountering dependency issues with core components and wknd sites as indicated below:

Java and mvn version

Maven 

Apache Maven 3.9.3 (21122926829f1ead511c958d89bd2f672198ae9f)

Generated project like 

mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate \

    -D archetypeGroupId=com.adobe.aem \

    -D archetypeArtifactId=aem-project-archetype \

    -D archetypeVersion=43 \

    -D appTitle="WKND Sites Project" \

    -D appId="wknd" \

    -D groupId="com.adobe.aem.guides" \

    -D artifactId="aem-guides-wknd" \

    -D package="com.adobe.aem.guides.wknd" \

    -D version="0.0.1-SNAPSHOT" \

    -D aemVersion="6.5.17"

I could use some assistance in getting unblocked. Any help would be greatly appreciated.

Hello @rohitya2 

Can you please share the following details? 

- AEM version

- Service pack used

The errors mean that there is a mismatch in the dependency that the code is expecting and whats available in AEM.  

Please assure that you are on AEM 6.5 + Service Pack 17. The maven command used has "6.5.17" as aemVersion

[rohitya2]

AEM version:- 

Adobe Experience Manager (6.5.0) -> coming from [http://localhost:4502/system/console/status-productinfo]

In the command, I specified version 6.5.17, but I am unsure how to install the service pack for version 17. You mentioned sharing any helpful documentation or links, which would be greatly appreciated.

hello @rohitya2 

Please visit Software Distribution https://experience.adobe.com/#/downloads/content/software-distribution/en/aem.html?package=/content/... 

Download the package and Install it Via Package manager http://localhost:4502/crx/packmgr/

It will take some time. Please tail error.log for activity. Once it stabilizes a bit, please validate if the dependency errors aee resolved/

Hello @rohitya2  - 

• I can see that you used AEM Version as "6.5.17" but do you have the service package also installed on AEM instance?
• Also, as per the tutorial link you shared it says, this tutorial uses the Maven AEM Project Archetype 35. However, you are using AEM archetype Version as 43

Correcting these should be solving the problem.

Hello @Tanika02, I have tried using the version specified in the documentation, but unfortunately, I encountered the same error. After conducting further investigation, I discovered new releases and their compatibilities. As a result, I adjusted the script to generate the project based on versions 43 and 6.5.17.

[Tanika02]

Okay!

@rohitya2  - Try cloning the Wknd site code and doing a build and see if it is getting successful. 

So basically, don't create an archetype project rather clone the wknd code from git and build https://github.com/adobe/aem-guides-wknd 

Have you tried this already?

[rohitya2]

Hi @Tanika02 Good idea I can try that out

[Tanika02]

I did tried this & the build is going successful. Check this should help.

Let me know if you face further difficulties.

[rohitya2]

Hi @Tanika02  I tried this and the build was successful however in the web console errors are still there and so when trying to access the wknd site it fails with same error as before

Hi @rohitya2 

Please align your environment with the Adobe recommendation for the latest archetype.

Archetype Historical Supported AEM Versions: https://github.com/adobe/aem-project-archetype/blob/develop/VERSIONS.md 

[rohitya2]

Hi ,@AsifChowdhury, You're spot on. To make sure we're in sync with 43, we're using these versions

Java -> 11.0.19
mvn -> 3.9.3
AEM -> 6.5.17 [in the script]

Hello @rohitya2 ,

With the previous discussion, you have a problem with the archetype and AEM SP version.

You can get confirmation with your SP version. Based on this version you need to setup your AEM project. For this you can check this documentation: https://github.com/adobe/aem-project-archetype/blob/develop/VERSIONS.md 

However, If your SP version is not the latest one you can download it from Software Distribution. 

https://experience.adobe.com/#/downloads/content/software-distribution/en/aem.html?package=/content/... 

To access this link may be you don't have that permission, ask your PM or Lead to download this for you.

Hope this helps you.

[rohitya2]

Hi @Sady_Rifat  Sure let me check on that as well
