Homebrew is a package manager for macOS, which will help us install the required software.

2. Install Maven

After installing Homebrew, use it to install Maven, which is essential for managing and building Java projects:

brew install maven

3. Install Java

Use Homebrew to install the latest version of Java. This will ensure compatibility with the project requirements:

brew install java

If a specific Java version is required, replace java with the appropriate version, such as openjdk@20.

To confirm Java was installed correctly, check the version:

java --version

This should display the installed Java version.
