Create a new Maven project in IntelliJ IDEA ( AI Generated )

Here’s how to create a new Maven project in IntelliJ IDEA:

---

Step 1: Open IntelliJ IDEA

1. Launch IntelliJ IDEA.
2. From the Welcome screen, click New Project. If you’re already in a project, go to File > New > Project.

---

Step 2: Select Maven as the Project Type

1. In the New Project dialog:
   • Select Maven under the Build System section.
   • Make sure the Project SDK is selected (e.g., Java 17). If no SDK is listed, click Add JDK and specify its location.
2. Click Next.

---

Step 3: Configure Maven Settings

1. GroupId: Enter your group identifier (e.g., com.example). This is usually the reverse of your domain name.
2. ArtifactId: Enter your artifact identifier (e.g., my-app). This is the name of your project.
3. Version: Use the default version (e.g., 1.0-SNAPSHOT).

Click Next.

---

Step 4: Specify the Project Location

1. Choose the location on your system where the project will be created.
2. Specify the project name (e.g., MyMavenProject).
3. Click Finish.

---

Step 5: Wait for IntelliJ to Import the Maven Project

1. IntelliJ will initialize the project and download required dependencies.
2. If prompted, allow IntelliJ to import the Maven project automatically.

---

Step 6: Verify the Project Structure

1. In the Project Explorer, you should see:
   • src/main/java: For your application code.
   • src/test/java: For your test cases.
   • pom.xml: Maven’s Project Object Model file.

---

Step 7: Configure the pom.xml

1. Open the pom.xml file and add dependencies if needed. For example, to add JUnit for testing:

   <dependencies>
       <dependency>
           <groupId>org.junit.jupiter</groupId>
           <artifactId>junit-jupiter</artifactId>
           <version>5.10.0</version>
           <scope>test</scope>
       </dependency>
   </dependencies>
   

2. Save the file. IntelliJ will automatically download the dependency.

---

Step 8: Create a Sample Java File

1. Right-click on src/main/java > New > Package, and name it (e.g., com.example).

2. Inside the package, create a new Java class:

   • Right-click > New > Java Class, and name it (e.g., Main).

   Add the following code to Main.java:

   package com.example;
   
   public class Main {
       public static void main(String[] args) {
           System.out.println("Hello, Maven Project!");
       }
   }
   

---

Step 9: Run the Application

1. Right-click on the Main class > Run 'Main.main()'.
2. Check the output in the Run tool window. You should see:

   Hello, Maven Project!
   

---

Step 10: Add Plugins or Additional Configuration (Optional)

If needed, you can add Maven plugins to the pom.xml. For example:

• Maven Compiler Plugin to specify the Java version:

  <build>
      <plugins>
          <plugin>
              <groupId>org.apache.maven.plugins</groupId>
              <artifactId>maven-compiler-plugin</artifactId>
              <version>3.11.0</version>
              <configuration>
                  <source>17</source>
                  <target>17</target>
              </configuration>
          </plugin>
      </plugins>
  </build>
