Package is duplicated in reactor error

Hi !
I am trying to build & deploy a project to AEM using Maven and when I run install command
mvn clean install -PautoInstallSinglePackage
I get below error:
Project 'com.adobe.aem.guides.wknd:aem-guides-wknd.ui.frontend:0.0.1-SNAPSHOT' is duplicated in the reactor

 

I tried changing groupId, artifactId & version but still same error.
Any idea how can I resolve this ?

Hi,

I downloaded the project fromhttps://github.com/adobe/aem-guides-wknd and ran the 

mvn clean install -PautoInstallSinglePackage

I did not see this error 

I execute this command from the project root folder multiple times, did not see error any of the time.

        I'm still seeing this issue. Is it resolved already? If yes, can you please share the solution.

          I was actually using below command to create the project:
          mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate -B -DarchetypeGroupId=com.adobe.aem -DarchetypeArtifactId=aem-project-archetype -DarchetypeVersion=25 -DappTitle="WKND Sites Project" -DappId="wknd" -DgroupId="com.adobe.aem.guides.wknd" -DartifactId="aem-guides-wknd" -Dversion="0.0.1-SNAPSHOT" -DaemVersion="cloud"

           

          But seems like there is difference in the project downloaded automatically vs Git project link. When we generate project, not all the modules of project gets created hence pop.xml mis-matches.

           

          Thanks.
