In this section, we will guide you through the initial steps required to set up your capstone project. This includes creating the project structure, configuring the necessary tools, and ensuring that your development environment is ready for implementation. By the end of this section, you will have a fully configured project ready for coding.

Before diving into the setup, it's crucial to clearly define the requirements and scope of your project. This will help you understand what tools and configurations are necessary.

• Project Goals: What is the main objective of your project?
• Features: List the key features your project will include.
• Technology Stack: Identify the technologies and libraries you will use (e.g., Groovy, Gradle, Spock, etc.).
• Dependencies: Determine any external libraries or frameworks required.

A well-organized project structure is essential for maintainability and scalability. Here, we will create a basic directory structure for a Groovy project.

1. Create the Root Directory:

   mkdir my-groovy-project
   cd my-groovy-project
   

2. Create Source Directories:

   mkdir -p src/main/groovy src/main/resources src/test/groovy src/test/resources
   

3. Create Gradle Build Files:

   • build.gradle:

     plugins {
         id 'groovy'
     }
     
     repositories {
         mavenCentral()
     }
     
     dependencies {
         implementation 'org.codehaus.groovy:groovy-all:3.0.9'
         testImplementation 'org.spockframework:spock-core:2.0-groovy-3.0'
     }
     
     test {
         useJUnitPlatform()
     }
     

   • settings.gradle:

     rootProject.name = 'my-groovy-project'
     

Ensure that your development environment is set up correctly to work with Groovy and Gradle.

1. Install Java Development Kit (JDK):

   • Ensure you have JDK 8 or higher installed. You can check your Java version with:

     java -version
     

2. Install Groovy:

   • Download and install Groovy from the official website or use a package manager like SDKMAN:

     sdk install groovy
     

3. Install Gradle:

   • Similarly, you can install Gradle using SDKMAN:

     sdk install gradle
     

4. IDE Setup:

   • Use an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse. Ensure the IDE supports Groovy and Gradle.

Using version control is essential for tracking changes and collaborating with others.

1. Initialize Git Repository:

   git init
   

2. Create .gitignore File:

   *.class
   *.log
   .gradle/
   build/
   

   • Add the .gitignore file to exclude unnecessary files from version control.

3. Commit Initial Setup:

   git add .
   git commit -m "Initial project setup"
   

Finally, verify that your setup is correct by running a simple Groovy script and a test.

1. Create a Simple Groovy Script:

   • src/main/groovy/HelloWorld.groovy:

     class HelloWorld {
         static void main(String[] args) {
             println 'Hello, Groovy!'
         }
     }
     

2. Create a Simple Test:

   • src/test/groovy/HelloWorldTest.groovy:

     import spock.lang.Specification
     
     class HelloWorldTest extends Specification {
         def "test HelloWorld script"() {
             expect:
             true
         }
     }
     

3. Run the Script:

   gradle run
   

4. Run the Tests:

   gradle test
   

If everything is set up correctly, you should see the output "Hello, Groovy!" and the test should pass.

In this section, you have successfully set up the initial structure and configuration for your Groovy capstone project. You are now ready to start implementing the features and functionalities defined in your project requirements. In the next section, we will dive into the implementation phase, where you will start coding your project.
