Error building AEM Archetype 23

View profile · 22-06-2020

Hello all,

I had an issue recently when trying to use the latest AEM Maven Archetype (23) for my personal use.

Problem

I used the following command (based on the command provided in the README):

mvn -B archetype:generate \
 -D archetypeGroupId=com.adobe.granite.archetypes \
 -D archetypeArtifactId=aem-project-archetype \
 -D archetypeVersion=23 \
 -D appTitle="My Site" \
 -D appId="mysite" \
 -D groupId="com.mysite" \
 -D frontendModule=general \
 -D includeExamples=n

It resulted in the following error:

Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate (default-cli) on project standalone-pom: Execution default-cli of goal org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate failed: A required class was missing while executing org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate: org/apache/ivy/Ivy

Solution

I solved the issue by specifying the latest version of maven-archetype-plugin (v3.1.2):

mvn -B org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate \
 -D archetypeGroupId=com.adobe.granite.archetypes \
 -D archetypeArtifactId=aem-project-archetype \
 -D archetypeVersion=23 \
 -D appTitle="My Site" \
 -D appId="mysite" \
 -D groupId="com.mysite" \
 -D frontendModule=general \
 -D includeExamples=n

Which results in:

...
