AEM Groovy Console replacement? Extending ACS Commons Managed Control process (MCP)

Problem Statement:

What is MCP? How to extend MCP in your current project.


Extend MCP in your current project structure and add the relevant POM changes


MCP (Manage Controlled Processes) is both a dashboard for performing complex tasks and also a rich API for defining these tasks as process definitions. In addition to kicking off new processes, users can also monitor running tasks, retrieve information about completed tasks, halt work, and so on.

The groovy console is an awesome tool to write short scripts to execute some of the content updates but due to increase security and safety issues, the AMS team is not allowing to install Groovy Console in the author/publish environment in Production and there is no other way we can run the groovy console on pubs. Hence ACS commons MCP would be the better replacement for running these kinds of bulk updates using the beautiful console provided by ACS Commons.

How to use MCP?

Process Manager: How to navigate and access ACS Commons MCP process manager

Tools: Tools that comes OOTB when you use MCP tools

Operations: How to use and maintain the MCP process

In order to extend the MCP process, create a separate module called mcp under your project directory and add the following dependencies as shown below:

Add the following code into all module pom.xml to embed this new module

Create the packages and start your first process:

For MCP process to pick up your new process, you need to create a service that implements ProcessDefinitionFactory and override getName method to provide the process name to show under the list of process.

MCP process list

createProcessDefinitionInstance to create a new instance of this process.

package com.mysite.mcp.process;

import org.osgi.service.component.annotations.Component;
import com.adobe.acs.commons.mcp.ProcessDefinitionFactory;

@Component(service = ProcessDefinitionFactory.class, immediate = true)
public class ExampleProcessFactory extends ProcessDefinitionFactory<ExampleProcess> {	
	public String getName() {
		return "Example PRocess";
	protected ExampleProcess createProcessDefinitionInstance() {
		return new ExampleProcess();

Create Process Implementation:

Process implementation class extends ProcessDefinition and you can have multiple form fields to accept the author’s input.

Process Input fields

You can learn more about form fields here

You need to override:

init – to run initiallise the process

build process – define the Action and add the description of the process

storeReport – Basically used to save the action results under the specified path

package com.mysite.mcp.process;

import java.util.ArrayList;
import java.util.EnumMap;
import java.util.List;
import javax.jcr.RepositoryException;
import com.adobe.acs.commons.fam.ActionManager;
import com.adobe.acs.commons.mcp.ProcessDefinition;
import com.adobe.acs.commons.mcp.ProcessInstance;
import com.adobe.acs.commons.mcp.form.FormField;
import com.adobe.acs.commons.mcp.model.GenericReport;

public class ExampleProcess extends ProcessDefinition {
	private static final String REPORT_SAVE_PATH = "/jcr:content/report";
	private final List<EnumMap<ReportColumns, Object>> reportRows = new ArrayList<>();
    GenericReport genericReport = new GenericReport();
    @FormField(name = "Enter Text",
            description = "Example text to be reported",
            required = false,
            options = {"default=enter test text"})
    private String emapleText;
    public void buildProcess(ProcessInstance instance, ResourceResolver rr) throws RepositoryException, LoginException {        
        instance.defineCriticalAction("Running Example", rr, this::reportExampleAction);
        instance.getInfo().setDescription("Executing Example Process");
	protected void reportExampleAction(ActionManager manager) {
	private void record(String emapleText) {
		 final EnumMap<ReportColumns, Object> row = new EnumMap<>(ReportColumns.class);
		 row.put(ReportColumns.SERIAL, 1);
	        row.put(ReportColumns.TEXT, emapleText);

    public void storeReport(ProcessInstance instance, ResourceResolver rr) throws RepositoryException, PersistenceException {
        genericReport.setRows(reportRows, ReportColumns.class);
        genericReport.persist(rr, instance.getPath() + REPORT_SAVE_PATH);

    public void init() throws RepositoryException {
    public enum ReportColumns {
        SERIAL, TEXT

Once the execution is complete we can save and see the report results:
