While trying to create AEM 6.4 project using Adobe Maven Archetype 13 using the following command:

"mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate -DarchetypeGroupId=com.adobe.granite.archetypes -DarchetypeArtifactId=aem-project-archetype -DarchetypeVersion=13 -DarchetypeCatalog=https://repo.adobe.com/nexus/content/groups/public/"

I am getting following error:

<!-- mirrors | This is a list of mirrors to be used in downloading artifacts

from remote repositories. | | It works like this: a POM may declare a repository

to use in resolving certain artifacts. | However, this repository may have

problems with heavy traffic at times, so people have mirrored | it to several

places. | | That repository definition will have a unique id, so we can create

a mirror reference for that | repository, to be used as an alternate download

site. The mirror site will be the preferred | server for that repository.

| -->

<mirrors>

<!-- mirror | Specifies a repository mirror site to use instead of a given

repository. The repository that | this mirror serves has an ID that matches

the mirrorOf element of this mirror. IDs are used | for inheritance and direct

lookup purposes, and must be unique across the set of mirrors. | <mirror>

Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url>

</mirrors>

<!-- profiles | This is a list of profiles which can be activated in a variety

of ways, and which can modify | the build process. Profiles provided in the

settings.xml are intended to provide local machine- | specific paths and

repository locations which allow the build to work in the local environment.

| | For example, if you have an integration testing plugin - like cactus

- that needs to know where | your Tomcat instance is installed, you can provide

a variable here such that the variable is | dereferenced during the build

process to configure the cactus plugin. | | As noted above, profiles can

be activated in a variety of ways. One way - the activeProfiles | section

of this document (settings.xml) - will be discussed later. Another way essentially

| relies on the detection of a system property, either matching a particular

value for the property, | or merely testing its existence. Profiles can also

be activated by JDK version prefix, where a | value of '1.4' might activate

a profile when the build is executed on a JDK version of '1.4.2_07'. | Finally,

the list of active profiles can be specified directly from the command line.

| | NOTE: For profiles defined in the settings.xml, you are restricted to

specifying only artifact | repositories, plugin repositories, and free-form

properties to be used as configuration | variables for plugins in the POM.

| | -->

<profiles>

<!-- profile | Specifies a set of introductions to the build process, to

be activated using one or more of the | mechanisms described above. For inheritance

purposes, and to activate profiles via <activatedProfiles/> | or the command

line, profiles have to have an ID that is unique. | | An encouraged best

practice for profile identification is to use a consistent naming convention

| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey',

'user-brett', etc. | This will make it more intuitive to understand what

the set of introduced profiles is attempting | to accomplish, particularly

when you only have a list of profile id's for debug. | | This profile example

uses the JDK version to trigger activation, and provides a JDK-specific repo.

<profile> <id>jdk-1.4</id> <activation> <jdk>1.4</jdk> </activation> <repositories>

<repository> <id>jdk14</id> <name>Repository for JDK 1.4 builds</name> <url>http://www.myhost.com/maven/jdk14</url>

<layout>default</layout> <snapshotPolicy>always</snapshotPolicy> </repository>

</repositories> </profile> -->

<!-- | Here is another profile, activated by the system property 'target-env'

with a value of 'dev', | which provides a specific path to the Tomcat instance.

To use this, your plugin configuration | might hypothetically look like:

| | ... | <plugin> | <groupId>org.myco.myplugins</groupId> | <artifactId>myplugin</artifactId>

| | <configuration> | <tomcatLocation>${tomcatPath}</tomcatLocation> | </configuration>

| </plugin> | ... | | NOTE: If you just wanted to inject this configuration

whenever someone set 'target-env' to | anything, you could just leave off

the <value/> inside the activation-property. | <profile> <id>env-dev</id>

<activation> <property> <name>target-env</name> <value>dev</value> </property>

</activation> <properties> <tomcatPath>/path/to/tomcat/instance</tomcatPath>

</properties> </profile> -->

<profile>

Could anyone please help me out.

Could not transfer artifact org.apache.maven.plugins:maven-archetype-plugin:pom:2.4 from/to adobe (https://repo.adobe.com/nexus/content/groups/public/): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target -> [Help 1]

Check if you're able to access "https://repo.adobe.com/nexus/content/groups/public" ​via browser? If yes, then fix your cacerts- download the repo.adobe.com cert and add it to your keystore. If not, then your network proxy is the root cause, try different network/machine and test the same.

You could also configure a proxy in your settings.xml if you have one available.

Is there a specific reason you are using such an old version of archetype? Try using the latest archetype[1] and check[2] for more details on the project setup. There might be an issue with the settings.xml. Everything is explained at [2]
