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.
