How to pass system property to Gradle task

Question

I\'m using Gradle spring-boot plugin and I need to select a spring active profile for the test run.

How do I pass spring.profiles.active sy

Answer 1

There is no generic way to pass system properties to a task. In a nutshell, it's only supported for tasks that fork a separate JVM.

The bootRunLocal task (as defined above) will not execute in a separate JVM, and calling execute() on a task isn't supported (and would have to happen in the execution phase in any case). Tests, on the other hand, are always executed in a separate JVM (if executed by a Test task). To set system properties for test execution, you need to configure the corresponding Test task(s). For example:

test {
    systemProperty "spring.profiles.active", "local"
}

For more information, see Test in the Gradle Build Language Reference.

Answer 2

For gradle 2.14 below example works. I have added as below.
When System.properties['spring.profiles.active'] is null then default profile is set.

  bootRun {
       systemProperty 'spring.profiles.active', System.properties['spring.profiles.active']
    }

command line example

gradle bootRun -Dspring.profiles.active=dev
