Hello @monish_gavali 

Please assure that the WKND package is compatible with your AEM version

Hi @monish_gavali ,
It's a problem of your local AEM setup. I would suggest you to reinstall it from scratch and follow the instructions carefully.

I have faced some similar issue long back and for me i have revisited everthing carefully and it got resolved for me. I usually follow the following steps for any new project setup.Give it a try and see if it works for you.
1. Install all prerequisite software, java, maven, node.js etc. mentioned here

2. Setup AEM 6.5+ Instance and make sure it is up and running

3. Create a new Project structure using the "maven-archetype" command

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=39 \
    -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="cloud or 6.5.+"

5. Once Project structure got created successfully.

6. Run the command(mvn clean install) to build the project.

mvn clean install

7. Import it with Intellij or any IDE that you want to use.
8. Finally Run mvn clean install -PautoInstallSinglePackage

mvn clean install -PautoInstallSinglePackage
