Install Gradle into your machine, here are the Gradle installation steps: https://docs.gradle.org/current/userguide/installation.html#installation

After successful installation of Gradle, below command should work in your command prompt/terminal window.

> gradle -v

------------------------------------------------------------
Gradle <<gradle version>>
------------------------------------------------------------

Now navigate to the maven root project directory(where pom.xml exists) and execute the below command:

 > gradle init 

When you run the command, gradle basically pars the existing pom.xmls and generates the corresponding Gradle build scripts. Gradle will also create a settings script if you’re migrating a multi-project build.

The new Gradle build includes the following:

• All the custom repositories that are specified in the POM
• External and inter-project dependencies
• The appropriate plugins to build the project

Once successful migration of the project, you can run the below command to build the gradle project.

> gradle build

This will run the tests and produce the required artifacts without any extra intervention on your part.

Note: If your project contains multiple modules in which each module have its own pom with dependencies, then you may need to run `gradle init` command in each directory where ever pom exists.
