Rhino

[erwan]

Here is a pull request to be able to use LessCss with Rhino (Javascript for the JDK). The advantage is that over NodeJS is that you can embedd rhino.jar in a repository, and as soon as there is Java installed on a machine you can compile less files to css.

In particular, you can make it an ant task that will not require you to have NodeJS or anything else installed on your machine.

Example:

<!-- Compile LessCSS -->
<macrodef name="lessjs">
    <attribute name="input" />
    <attribute name="output" />
    <sequential>
        <java jar="./${dir.build.tools}/${tool.rhino}" fork="true" output="@{output}">
            <arg path="./${dir.build.tools}/${tool.less}" />
            <arg path="@{input}" />
        </java>
        <echo>Lessjs: generated @{output}</echo>
    </sequential>
</macrodef>

<target name="compilecss">
    <lessjs input="./public/css/main.less" output="./public/css/main.css" />
</target>

I don't know the actual quality of the provided code (I'm not a Javascript guy) but 'native' Rhino support in LESS JS compiler would be great.
I'm working on a Maven plugin under the Codehaus Mojo umbrella and I'm also using Rhino.
There have been few Java projects provding Java compilation already but each is different but all of them have to do stuff to resolve imports. I'm now also experimenting myself using Rhino and EnvJs but off course I would prefer better integration as proposed by erwan.

How does this project about such integration, and what timeframes should we think then?

A lot of people are using LESS with java, I think this is a good addition.

Great news. When are you planning for a new a release containing this?
