Gradle build spring boot app as war with active profile

Question

I would like to package my spring boot application as war for a specific profile. That can be done with setting spring.profiles.active=profile name in application.properties file. Is it possible to set it as a parameter when building war eg. gradle build --spring.profiles.active=profile name?

Answer 1

It sounds like you want to bake the value of spring.profiles.active into the war when it's built. You can do so using Gradle's support for resource filtering. Configure your application.properties like this:

spring.profiles.active=@activeProfiles@

And then apply filtering in your build.gradle to replace @activeProfiles@ with the value of a property:

processResources {
    filter org.apache.tools.ant.filters.ReplaceTokens, tokens: [
        activeProfiles: activeProfiles
    ]
}

In this example, I've used a property named activeProfiles. You'd then have to supply a value when you run the build:

./gradlew -PactiveProfiles=foo build
