How to get version attribute from a gradle build to be included in runtime Swing application

I like creating a properties file during the build. Here’s a way to do that from Gradle directly:

task createProperties(dependsOn: processResources) {
  doLast {
    new File("$buildDir/resources/main/version.properties").withWriter { w ->
        Properties p = new Properties()
        p['version'] = project.version.toString()
        p.store w, null
    }
  }
}

classes {
    dependsOn createProperties
}
