Add CDI to an existing project

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

2. Add the CDI library, and make sure its version matches the rest of your project:

   Jakarta EE

   <dependency> <groupId>jakarta.enterprise</groupId> <artifactId>jakarta.enterprise.cdi-api</artifactId> <version>4.1.0</version> </dependency>

   Java EE

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

   Jakarta EE

   implementation 'jakarta.enterprise:jakarta.enterprise.cdi-api:4.1.0'

   Java EE

   implementation 'javax.enterprise:cdi-api:2.0.SP1'

   Jakarta EE

   implementation("jakarta.enterprise:jakarta.enterprise.cdi-api:4.1.0")

   Java EE

   implementation("javax.enterprise:cdi-api:2.0.SP1")

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