|
<p>Since our <a href="/news/2015/08/04/jrubygradle-one-point-oh/">major 1.0
|
|
announcement</a> at this past year’s <a href="http://2015.jrubyconf.eu">JRubyConf EU</a>
|
|
we’ve had a pretty steady stream of improvements and bug fixes in a total
|
|
of four patch releases (1.0.0 - 1.0.4), so we’re due for a big meaty
|
|
feature release! The most impactful feature, sponsored in part by
|
|
<a href="https://lookout.com">Lookout, Inc.</a>, is the support for <strong>dependency
|
|
resolution without a 3rd party proxy.</strong></p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>By default, JRuby/Gradle relies on a third party instance of the
|
|
<a href="https://github.com/torquebox/rubygems-servlets">rubygems-servlets</a> proxy
|
|
which represents a Rubygem repository in a Maven-compatible format, allowing
|
|
tools like Gradle or Maven to prepare a dependency graph using Ruby gems. With
|
|
1.1, codenamed "<a href="https://en.wikipedia.org/wiki/Dresden">Dresden</a>", release
|
|
we’ve <em>embedded</em> the proxy software directly into the Gradle process. With the
|
|
<code>rubygems()</code> function, users can use gem dependencies from
|
|
<strong>any</strong> repository, whether it’s a public repository like
|
|
<a href="https://rubygems.org">rubygems.org</a> or an internal Ruby gem repository.</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>Currently this behavior is <strong>defaulted to off</strong> so users must explicitly
|
|
enable it, e.g.:</p>

|
<p>Earlier this year the <a href="http://gradle.org">Gradle</a> project released version
|
|
<a href="https://docs.gradle.org/2.5/release-notes">2.5</a> with a heap of new features
|
|
and improvements. One of the most touted of those features is an incubating
|
|
feature (read: beta) named
|
|
<a href="https://docs.gradle.org/current/userguide/continuous_build.html">Continuous
|
|
Build</a> which automatically re-executes tasks after a file change. Rubyists may
|
|
recognize that this functionality is similar to what
|
|
<a href="http://guardgem.org/">the guard gem</a> provides.</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>What makes "continuous build" special is that it makes use of the <em>existing</em>
|
|
build data present in your Gradle build. Using a
|
|
<a href="https://docs.gradle.org/current/userguide/more_about_tasks.html#sec:task_inputs_outputs">task’s
|
|
inputs</a> the continuous build feature can automatically "watch" the appropriate
|
|
files to re-execute your task, or your tasks dependent tasks, automatically as
|
|
they change!</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>For users JRuby/Gradle this means that upgrading to Gradle 2.5 or later, and
|
|
ensuring your <code>build.gradle</code> declares task inputs and continuous build will
|
|
"just work!" Consider the following example for running

|
<p>What makes this functionality exceptionally powerful for JRuby/Gradle users is
|
|
that it respects the task inputs but also the task dependency graph. If my <code>spec</code>
|
|
task declares a dependency on the <code>compileJava</code> task, whenever my Java source
|
|
code changes, that will trigger a re-execution of <code>compileJava</code> and in turn
|
|
<code>spec</code>!</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>So when you’re authoring tasks, even if you’re not this feature right now, be
|
|
sure to declare task inputs. That build metadata can unlock lots of interesting
|
|
functionality as Gradle continues to improve!</p>

<p>Continuous build is one of many examples of powerful Gradle functionality which

can easily used in JRuby/Gradle, I hope you find it useful!</p>

<p>A couple weeks ago, <a href="https://github.com/ysb33r">Schalk</a>,
|
|
<a href="https://github.com/mkristian">Christian</a> and
|
|
<a href="https://github.com/rtyler">I</a> were fortunate enough to participate in the
|
|
wonderful <a href="http://2015.jrubyconf.eu">JRubyConf EU 2015</a> in Potsdam Germany.
|
|
In the days that preceeded the conference we pulled together and finished up
|
|
what would become the <a href="/news/2015/08/04/jrubygradle-one-point-oh/">1.0
|
|
release</a> of the core plugins. Just in time for my presentation to introduce the
|
|
JRuby/Gradle toolchain to the audience.</p>

<p>Below is a video recoded by <a href="http://confreaks.tv">Confreaks.tv</a> of the talk

<p>The <a href="http://confreaks.tv/events/jrubyconf2015">other sessions</a> are also

|
|
<p>The JRuby/Gradle project was originally started to address the challenges faced
|
|
when attempting to build complex Ruby applications based on
|
|
<a href="http://jruby.org">JRuby</a>. With such applications it is desirable to leverage
|
|
the vast libraries available to JVM-based languages, as well as many of the
|
|
user-friendly gems built by Ruby developers</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>After trying to make multiple tools, which weren’t designed to support non-Java
|
|
projects, work with Ruby <a href="https://github.com/rtyler">R. Tyler Croy</a> started
|
|
building a prototype with Gradle to package up a JRuby application as a jar.
|
|
Shortly after publishing the prototype, <a href="https://github.com/ysb33r">Schalke
|
|
W. Cronje</a> discovered the fledgling project and with his Gradle development
|
|
experience helped bring it from a weekend hack project to a well-tested,
|
|
well-structured set of Gradle plugins. Eventually
|
|
<a href="https://github.com/mkristian">Christian Meier</a>, whose
|
|
link:https://github.com/torquebox/rubygems-servlets] code helped make the
|
|
project originally possible, joined the team to help improve support in JRuby
|
|
itself for the different embedded operating modes that the JRuby/Gradle
|
|
toolchain makes use of.</p>
