How to develop a Custom Keywords Plugin

In this tutorial, we’ll introduce a detail process of sharing custom keywords as plugins. Custom Keywords plugins are available since Katalon Studio 6.0.6.

Develop a Custom Keywords plugin

  • Sample:
  • A Custom Keywords plugin is essentially a normal Katalon Studio project with some Custom Keywords implementation. So the steps are quite simple:
    • Create a new Katalon Studio project.
    • Implement your Custom Keywords.
    • Test Cases can be added to help verify these Custom Keywords and to serve as samples for plugin users.

Package the Custom Keywords plugin

  • In the Keywords folder, add a katalon-plugin.json file with the following format:
  "keywords": [keywordClass1, keywordClass2]


	"keywords": ["com.katalon.plugin.keyword.excel.ExcelReadKeywords", "com.katalon.plugin.keyword.excel.ExcelWriteKeywords"]
  • In the project's root folder add a build.gradle file
plugins {
  id 'java'
  id 'groovy'
  id 'com.github.johnrengelman.shadow' version '4.0.4'
  id "com.katalon.gradle-plugin" version "0.0.6"

repositories {

sourceSets {
  main {
    groovy {
      srcDirs = ['Keywords', 'Include/scripts/groovy']
      srcDir 'Libs'

shadowJar {
  exclude 'Temp*.class'

katalon {
  dependencyPrefix = "com.katalon"
  minimize = false

Install Gradle and run the following command, then checking the build/libs for the plugin’s JAR package.

gradle katalonPluginPackage


  • If you run the above command inside an existing project, please open that project with Katalon Studio first.

  • To execute your katalonPluginPackage across platforms, open the plugin project using Katalon Studio first to repopulate the .classpath file. The package task use these paths to look up Katalon Studio libraries.

Test the Custom Keywords plugin

Publish the plugin

Once you’re done developing your plugins, please submit them to Katalon Store. We’ll review your contents against our policies before approving to list them on the Store.
