Using FMPP with Gradle

I am attempting to convert an ant task which uses fmpp over to gradle. I am unable to get my project to build. I have the following in my build.xml file:

<project name="website">
    <property file="build.properties" />
    <property name="src.dir" location="src" />
    <property name="build.dir" location="build" />
    <taskdef name="fmpp" classname="fmpp.tools.AntTask">
        <classpath>
            <pathelement location="lib/fmpp.jar"/>
        </classpath>
    </taskdef>
    <target name="clean">
        <delete dir="${build.dir}" />
    </target>
    <target name="dist">
        <fmpp sourceRoot="${src.dir}" outputRoot="${build.dir}">
            <data expandProperties="yes">
                base_url: ${base_url}
                google_analytics_number: ${google_analytics_number}
                mail_user: ${mail_user}
                mail_password: ${mail_password}
                mail_recipient: ${mail_recipient}
                upload_folder: ${upload_folder}
                host: ${host}
                port: ${port}
            </data>
        </fmpp>
    </target>
</project>

my build.gradle file looks like this

ant.taskdef(name: 'fmpp', classname:'fmpp.tools.AntTask') {
    classpath {
        fileset(dir: 'lib', includes: '*.jar')
    }
}

ant.fmpp(sourceRoot:"src", outputRoot :"build") {
    data(expandProperties: 'yes'){
        base_url = base_url
        google_analytics_number = google_analytics_number
        mail_user = mail_user
        mail_password = mail_password
        mail_recipient = mail_recipient
        upload_folder = upload_folder
        host = host
        port = port
    }
}

but when I run it I get the following error

FMPP processing session failed. Caused by: freemarker.core.InvalidReferenceException: Expression base_url is undefined on line 15, column 47 in data/header.htm.

So it seems like the template variable in the htm file isn't being properly picked up and implemented in my my build. I am not sure how to get around this. There are a few gradle plugins for fmpp but have very limited documentation and I am having difficulty getting any of them to work. If any one has suggestions or a work around it would be greatly appreciated.

*** Update

Here is an example of the htm file that's trying to be applied

  <head>
    <?php
        error_reporting(E_ALL);
        ini_set('display_errors', 1);
        $page = basename($_SERVER['PHP_SELF']);
        require_once($_SERVER['DOCUMENT_ROOT'] . '/js/functions.php');
    ?>
    <title>
        <#if title??> ${title}
            <#else> CompSci Resources, LLC | The Complete EDGAR and XBRL Filing Platform, and more!
        </#if>
    </title>

Solution

  • The problem lies in the fact that both properties read from gradle.properties and data properties are named exactly the same. To fix it you need to refer to value hidden under property with project instance, e.g.:

    base_url = project.base_url

    Have a look at the demo I've just prepared. It runs without any errors. If you rename properties in gradle.properties you may skip project, this is the case for port2 property - renamed on purpose.
