Prerequisite for creating AEM Project using Maven.
To run AEM and to develop a project in AEM you need below softwares installed in your PC.
- Java (JDK 8 or more)
- Maven
- Eclipse/IntelliJ (I personally prefer IntelliJ Idea Community Edition as it is very convenient for debug with AEM)
- Notepad++/Brackets
Java
Download and Install java from below link:
https://www.oracle.com/technetwork/java/javase/downloads/index.html
After installing java, create environment variable JAVA_HOME which points to jdk installation.
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_102 path = %JAVA_HOME%/bin;
Maven
You can use Maven to build an OSGi bundle that contains a Sling Servlet. Maven manages required JAR files that a Java project needs in its class path. Instead of searching the Internet trying to find and download third-party JAR files to include in your project’s class path, Maven manages these dependencies for you.
You can download Maven 3 from the following URL:
http://maven.apache.org/download.html
Note: It is recommended that you use Maven 3.0.3 or greater.
After you download and extract Maven, create an environment variable named M2_HOME. Assign the Maven install location to this environment variable. For example: C:\Programs\Apache\apache-maven-3.0.4
M2_HOME = C:\apache-maven-3.6.0-bin\apache-maven-3.6.0 path = %M2_HOME%/bin;
Check your installation by using below command.
mvn -version
you should see maven version and installation directory.
AEM
Steps to run AEM for the first time:
- In your file directory create folder named aem.
- Under aem directory create another folder named author.
- Get aem jar and rename it to aem-author-P4502.jar which indicates to run as author instance on port number 4502 (aem-publish-P4503 for publish instance to run on port 4503) Note: default instance will be author and port will be 4502 if you don’t rename.
- Copy license file and paste it in folder with AEM jar.
You can install aem in three ways
To start up the instance in a GUI environment, just double-click the aem-author-p5402.jar
Alternative, you can launch AEM from the command line. For a 32-bit Java VM enter the following:
java -Xmx1024M -jar cq-quickstart-6.3.0.jar
For a 64-bit VM, enter:
java -XX:MaxPermSize=256m -Xmx1024M -jar cq-quickstart-6.3.0.jar
AEM will take a few minutes to unpack the jar file, install itself, and start up. The above procedure results in: an AEM author instance running on localhost on port 4502.
To access the instance point your browser to: http://localhost:4502
login with default credentials username: admin, password: admin
You will be taken to AEM Start Screen.
