Create a new Java Enterprise project with CDI

1. Click New Project on the Welcome screen or select File | New | Project.

2. From the Generators list, select Java Enterprise.

4. Select the Create Git repository option to place the new project under version control.

5. From the JDK list, select the JDK that you want to use in your project.

   If the JDK is installed on your computer, but not defined in the IDE, select Add JDK and specify the path to the JDK home directory.

   If you don't have the necessary JDK on your computer, select Download JDK.

   

6. On the next step of the wizard, select the Java EE version to be supported.

7. From the Dependencies list, select the Contexts and Dependency Injection (CDI) checkbox.

Enable CDI support for an existing project

If you already have a Java Enterprise web application, you can add the CDI framework support.

1. Open the build file in the editor (pom.xml or build.gradle depending on the build tool that you use in your project).

2. Add the following dependency, but make sure to change the version according to your project's requirements:

   <dependency> <groupId>javax.enterprise</groupId> <artifactId>cdi-api</artifactId> <version>2.0.SP1</version> <scope>provided</scope> </dependency>

   This is what the file pom.xml will look like after inserting the code:

   

   compileOnly('org.apache.deltaspike.cdictrl:deltaspike-cdictrl-api:1.9.5')

   This is what the file build.gradle will look like after inserting the code:

   

3. Press Ctrl+Shift+O to import the changes.
