How to run Spring Boot with a dev profile and Gradle

I like to use the dev profile in my Spring Boot projects to store the application configuration for development. Spring Boot will conviniently load the configuration dedicated to the profile we've selected when starting the app (i.e. application-dev.yaml).

To use the dev profile, all I need to do with maven is to pass -Dspring.profiles.active=dev property to my spring-boot:run target.

Gradle's bootRun task supports passing --args='--spring.profiles.active=dev' with the Spring Boot Gradle plugin.

There's an alternative too. All we need is a task that would set the property, before spring boot app starts.

Here's an example from build.gradle.kts:

tasks.register("bootRunDev") {
    group = "application"
    description = "Runs the Spring Boot application with the dev profile"
    doFirst {
        tasks.bootRun.configure {
            systemProperty("spring.profiles.active", "dev")
        }
    }
    finalizedBy("bootRun")
}

Usage:

$ ./gradlew bootRunDev

> Task :bootRun
  ,---.    ,-----. ,--.   ,--. ,------. 
 /  O  \  '  .--./ |   `.'   | |  .---' 
|  .-.  | |  |     |  |'.'|  | |  `--,  
|  | |  | '  '--'\ |  |   |  | |  `---. 
`--' `--'  `-----' `--'   `--' `------'
