How to use Maven Deployment for CQ5.6. documentation are available only for 5.6.1 and higher

Although this article was written for AEM 6, you can try and see if this works on 5.6. The POM file should work on AEM 5.6 (there is no AEM 6 specific dependencies).

We are using the vault tool to sync code between Eclipse and the JCR (available wiht 5.6).

I am going to test this article with AEM 5.6 as well. If required - we will update for 5.6.

Thanks a lot for the reply.

Am trying to build the Maven project using the 

mvn archetype:generate -DarchetypeRepository=http://repo.adobe.com/nexus/content/groups/public/ -DarchetypeGroupId=com.day.jcr.vault -DarchetypeArtifactId=multimodule-content-package-archetype -DarchetypeVersion=1.0.2 -DgroupId=com.aem.community -DartifactId=echoproject -Dversion=1.0-SNAPSHOT -Dpackage=com.aem.community -DappsFolderName=myproject -DartifactName="My Project" -DcqVersion="5.6.1" -DpackageGroup="My Company"

But Build is failing and getting the below error:

I copied the pom from adobe repository. may be there was an issue with the POM download from the path .

Thanks for giving the hint of adobe repository. Build is success!
