Hey all, I found out that whenever using Gradle Kotlin DSL with SpringBoot plugin and running

gradle bootRun -Dspring.profiles.active=local

the profile is not set, it only works if I set env var like

SPRING_PROFILES_ACTIVE=local gradle bootRun

why is that? Does

-D<prop>=<value>

not work with Kotlin DSL?

This likely has nothing to do with the DSL language. The

-D

option only passes a system property to the JVM that is running Gradle, not to any of the invoked tasks. https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_system_properties If you want to specify the profile from the Gradle command line you will have to wire a Gradle property to add the system property to the

bootRun

task. https://docs.gradle.org/current/dsl/org.gradle.api.tasks.JavaExec.html#org.gradle.api.tasks.JavaExec:systemProperties(java.util.Map)

I found this in their documentation: https://docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/htmlsingle/#running-your-application.passing-arguments So maybe this works:

./gradlew bootRun --args='--spring.profiles.active=local'

And below that it's also an example how to pass system properties to bootRun.
