Hi @vrokkham ,

I think there is a problem with the plugin. Can you please try building the project from console and add them to the server in eclipse, hope it does work.

Hi @santhosh_kumark , Thanks for the above response. but i'm facing issue with creating a project, with out project i couldn't build project from console. Hope you got my concern.

Hi @vrokkham 

Did you restart the eclipse once the plugin is installed? If not, please restart and try creating the project. 

For reference - http://www.aemcq5tutorials.com/tutorials/adobe-aem-cq5-tutorials/create-aem-multi-module-project/#cr...

Hope this helps... Happy learning 🙂

Hi @vrokkham 

Try to create project using command prompt using below link.

https://docs.adobe.com/content/help/en/experience-manager-learn/getting-started-wknd-tutorial-develo... 

[Vijayalakshmi_S]

Hi @vrokkham,

In the cmd prompt, use "mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate" instead of "mvn archetype:generate" specifying the explicit archetype plugin version. 

Archetype version 17 project uses plugin version 2.4.

Finally i was able to create project via command line following the steps provided in below link.

Thank You All for your time spending on this issue.

Hi, Vrokkham, i get the same problem with you. So far, i still can't solve it after trying all the possible solution from network.

If we still need to use the CMD to create the project, then i am not sure what's the usage of the AEM tool.

Is it really a bug of this tool or did you get any finding on this?
