spring-boot: project.version not accessible in application.properties with gradle build

In the docs here there is mention of using syntax like this this in application.properties to access a version number via actuator:

info.build.version=${project.version}

When using gradle, the project.version does not seem to be populated though, resulting in actuator just printing the “${project.version}” characters, not resolving the code to the version.

For the sake of testing that these variables can be resolved, I also tested this and it worked fine:

info.build.random=${random.long}

The docs state that this is a Spring Boot Maven feature, but I was hoping it would work for Gradle too. Is this expected to work for Gradle or is there an alternative perhaps?

If it’s of any help, here it my build.gradle file contents:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath('org.springframework.boot:spring-boot-gradle-plugin:1.1.5.RELEASE')
    }
}

repositories {
    mavenCentral()
}

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'spring-boot'


dependencies {
    // tag::jetty[]
    compile('org.springframework.boot:spring-boot-starter-web') {
        exclude module: 'spring-boot-starter-tomcat'
    }
    compile('org.springframework.boot:spring-boot-starter-jetty')
    // end::jetty[]
    // tag::actuator[]
    compile('org.springframework.boot:spring-boot-starter-actuator')
    // end::actuator[]
}

version = '1.0.0'
