How to get unused Components list in aem by using existing groovy script console on aem local instance

I have existing script created as a base to get a list of all components that currently are being used under /content/<myProject>/en.

 

To execute the script, I build and installed the groovy script console in my local aem instance.

 

I need a solution for to get a list of all components under /apps/<myProject>/components. And then to get seperate list for unused Components.

 

Please give me a better solution to get result.

Hello @gvk19694 

 

You already have the list of all used components.

List of all components can easily be generated

 

Now to find the list of all components not in use:

List<Integer> unusedComponents= new ArrayList<>(allComponents); unusedComponents.removeAll(usedComponents);

Assure that eaither all component paths should have full path from '/apps', else just remove it from all Strings

Hi @gvk19694,

You can use script like below. It's creating 2 lists on is including all the components form given path, and send that only contains unused components in it. At the end both list are printed.

Of course you have to set proper paths in the script replacing /content/<myProject>/en and /apps/<myProject>/components with real paths.

import javax.jcr.query.Query import com.day.cq.wcm.api.components.Component def allComponentsList = [] def unsedComponentsList = [] // getting list of all components resourceResolver.findResources("SELECT * FROM [cq:Component] AS s WHERE ISDESCENDANTNODE([/apps/<myProject>/components])", Query.JCR_SQL2).each { resource -> def component = resource.adaptTo(Component.class) allComponentsList.add(component) } // getting list of all unused components allComponentsList.each { component -> def resourceType = component.getResourceType() def numberOfComponentUsage = resourceResolver.findResources(""" SELECT * FROM [nt:base] AS s WHERE ISDESCENDANTNODE([/content/<myProject>/en]) AND s.[sling:resourceType] = '$resourceType'""", Query.JCR_SQL2).size() if (numberOfComponentUsage == 0) { unsedComponentsList.add(component) } } println "All components" allComponentsList.each {cmp -> println "Component title: $cmp.title, resource type: $cmp.resourceType"} println "Unused components" println unsedComponentsList.each {cmp -> println "Component title: $cmp.title, resource type: $cmp.resourceType"}
