Error while creating the new Maven projects - Caused by: java.lang.NoClassDefFoundError: org/apache/ivy/core/report/ResolveReport

I was getting the below exception while creating the AEM projects through Adobe Maven Arch Type 23, even the same issue was reported while generating the through Arch Type 22. 

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

Enabled the flag -e to get more detailed errors - the below expection was thrown while executing the maven command

Number of foreign imports: 1
import: Entry[import  from realm ClassRealm[maven.api, parent: null]]

After a long struggle identified the issue was not specific to the arch type and caused by the corrupted local maven repository, the issue got resolved after removing the org folder folder from the maven repository(renamed the folder to org_bak)

Ensure the system is connected to Wireless Network

Turn Off the Virtual Machine

The Java/Javac versions and the JAVA_HOME and PATH variables were configured properly.

gcloud-app-deploy-no-jdk

Also the java runtime was configured properly in appengine-web.xml

gcloud-app-deploy-no-jdk

After little struggle,  the root cause of the issue was with wrong configuration of PATH environment variable.

Other Java executables added to the PATH variable caused the SDK to choose the JRE version for deployment. 

gcloud-app-deploy-no-jdk


The issue got fixed after changing the order of PATH variable - moved up the JAVA bin path over other path configurations

How to include dynamic custom script to websites through GTM(Google Tag Manager) - Adobe Experience Manager(AEM)

How to include dynamic custom script to websites through GTM(Google Tag Manager) - Adobe Experience Manager(AEM)


Google Tag Manager is a tag management system that allows you to quickly and easily update tracking codes and related code fragments collectively known as "tags" on your website or mobile app. Once a small segment of Tag Manager code has been added to your project, you can easily configure and deploy your tag configurations from a web-based user interface without the need to deploy additional code in most cases. This reduces errors and frees you from having to involve a developer every time you need to make changes.

This post explains the approach to use Google Tag Manager(GTM) to include the dynamic scripts as part of Adobe Experience Manager(AEM) websites.


Create a free google tag manager account if one is not available

tagmanager-GTM


Install the GTM header and body scripts to the AEM website

tagmanager-GTM


tagmanager-GTM


Copy the head script to the header file and body script to body footer(start of body section)

tagmanager-GTM
