        filter(ReplaceTokens,
                tokens: [myAppVersion: MY_APP_VERSION])
    }
}


def allProcessResourcesTasks() {
    sourceSets*.processResourcesTaskName.collect {
        tasks[it]
    }
}

and my MY_APP_VERSION variable is defined in top-level build.gradle file:

ext {

    // application release version.
    // it is used in the ZIP file name and is shown in "About" dialog.
    MY_APP_VERSION = "1.0.0-SNAPSHOT"
}

and my resource file is in /webshared/src/main/resources/version.properties :

# Do NOT set application version here, set it in "build.gradle" file
# This file is transformed/populated during the Gradle build.
version=@myAppVersion@
