Have you noticed the placeholder “${version}” that’ll be replaced with the actual version in the build process. Then new gradle task need to be defined. So we can define a class extending DefaultTask in our build.gradle script.

class GenerateVersionFileTask extends DefaultTask {
    def templateLocation
    def destination

    File getDestination() {
        project.file(destination)
    }

    File getTemplateFile() {
        project.file(templateLocation)
    }

    String getTemplateContent() {
        getTemplateFile().getText('UTF-8').replace("\${version}", getVersion())
    }

    String getVersion() {
        project.version
    }

    @TaskAction
    def generate() {
        println 'Generating version file'
        def templateContent = getTemplateContent();
        def file = getDestination()
        file.parentFile.mkdirs()
        file.write(templateContent, 'UTF-8')
        println Version file generated'
    }
}

class GenerateVersionFileTask extends DefaultTask {

def templateLocation

def destination

File getDestination() {

project.file(destination)

}

File getTemplateFile() {

project.file(templateLocation)

}

String getTemplateContent() {

getTemplateFile().getText('UTF-8').replace("\${version}", getVersion())

}

String getVersion() {

project.version

}

@TaskAction

def generate() {

println 'Generating version file'

def templateContent = getTemplateContent();

def file = getDestination()

file.parentFile.mkdirs()

file.write(templateContent, 'UTF-8')

println Version file generated'

}
