How to generate an AEM Project

Today we will generate an AEM Project using a Maven archetype with the help of command line.

Prerequisites:

1. JDK should be installed

2. Maven should be installed

1. What is Maven Project? Apache Maven is a software project management and comprehension tool. All Adobe Experience Manager Projects leverage Maven Project to generate, build, and deploy code.
   

2. What is Maven Archetype? Archetype is a Maven project templating toolkit. AEM requires project code to be in particular structure. To generate this pre-created structure we use "aem-project-archetype" as an Archetype Id.

Paste the following into the command line to generate the project in batch mode and hit ENTER:

mvn -B archetype:generate \
    -D archetypeGroupId=com.adobe.aem \
    -D archetypeArtifactId=aem-project-archetype \
    -D archetypeVersion=35 \
    -D appTitle="WKND Sites Project" \
    -D appId="wknd" \
    -D groupId="com.adobe.aem.guides" \
    -D artifactId="aem-guides-wknd" \
    -D package="com.adobe.aem.guides.wknd" \
    -D version="0.0.1-SNAPSHOT" \
    -D aemVersion="cloud"

Please refer following link to find about available parameters: https://experienceleague.adobe.com/docs/experience-manager-core-components/using/developing/archetype/overview.html?lang=en#available-properties

This will create following project structure:

    |--- aem-guides-wknd/
        |--- all/
        |--- core/
        |--- ui.apps/
        |--- ui.apps.structure/
        |--- ui.config/
        |--- ui.content/
        |--- ui.frontend/
        |--- ui.tests /
        |--- it.tests/
        |--- dispatcher/
        |--- archetype.properties
        |--- pom.xml
        |--- README.md
        |--- .gitignore

To Deploy the project to running AEM instance, execute following command at project repository folder(in this case at aem-guides-wknd)

mvn clean install -PautoInstallSinglePackage

The Maven profile "autoInstallSinglePackage" compiles the project and deploys as a single package to the AEM instance. By default the port is set to 4502 with the credentials of admin:admin. You can update it in parent pom.xml

If you receive following message it means the build was successful and project was deployed to the AEM instance.
