Package is duplicated in reactor error

[AtulSingh]

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 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.

@AtulSingh -  Can you try doing mvn clean alone once ?


Thanks,

Project 'com.mysite:mysite.ui.frontend:1.0.0-SNAPSHOT' is duplicated in the reactor - I am still getting this error @Nikhil-Kumar, even after trying mvn clean once
