• Java-11

  mvn clean package

  If you want to skip Test Cases:

  mvn clean package -DskipTests

  This command will generate a target directory inside base directory. A packaged JAR file employees-0.0.1-SNAPSHOT.jar is generated on successful execution.

  Navigate to the target directory to run the application.

• Run the Spring Boot API from packaged JAR file

  java -jar employees-0.0.1-SNAPSHOT.jar
