Groovy Packaged by IOanyT Innovations - Rocky Linux 8

OVERVIEW :


Groovy is a dynamic programming language that runs on the Java Virtual Machine (JVM). It is designed to be concise and expressive, with a syntax that is similar to Java but with additional features that make it easier to write code and work with data. Some of its key features include closures, dynamic typing, and the ability to easily integrate with Java libraries. Groovy is often used for scripting, testing, and building web applications.


Groovy is a dynamic and optionally typed programming language that runs on the Java Virtual Machine (JVM).


Features of Groovy :

  • Groovy supports dynamic typing, which means that you don't have to declare the type of a variable before using it.

  • Groovy supports closures, which are blocks of code that can be assigned to a variable, passed as an argument to a method or returned as a value from a method.

  • Groovy has built-in support for creating DSLs, which are small, specialized programming languages that are designed to solve specific problems.

  • Groovy is designed to be fully compatible with Java, which means that you can use any Java library in your Groovy code.

  • Groovy has a simplified syntax compared to Java, which makes it easier to write and read code.

  • Groovy supports both runtime and compile-time meta-programming, which allows you to modify the behavior of your code at runtime or compile-time.

If it shows an access denied message run the following command, then run the above command again to connect via ssh.

chmod 400 [Path of key pair file]

Once launched in the Amazon EC2 Service, please connect to the instance via an SSH client using the ec2-user with the key pair associated at launch. Once connected as the ec2-user user, you will be able to sudo to the root user


Step 2. Verify the installation:

Follow the steps to verify the Groovy installation


1. Login with ssh
