have a fully functional PredictionIO setup. If you have not installed

id='installing-intellij-scala-plugin' class='header-anchors'>Installing
IntelliJ Scala Plugin</h3><p>First of all, you will need to install the <a
href="https://plugins.jetbrains.com/plugin/?id=1347";>Scala plugin</a> if you
have not already done so.</p><p>Go to the <em>Preferences</em> menu item, and
look for <em>Plugins</em>. You should see the following screen.</p><p><img
alt="IntelliJ Plugins"
src="/images/intellij/intelliJ-scala-plugin-09ee074a.png"/></p><p>Click
<em>Install JetBrains plugin...</em>, the search for <em>S
cala</em>. You should arrive at something similar to the following.</p><p><img
alt="Scala Plugin"
src="/images/intellij/intellij-scala-plugin-2-592c697f.png"/></p><p>Click the
green <em>Install plugin</em> button to install the plugin. Restart IntelliJ
IDEA if asked to do so.</p><h3 id='setting-up-the-engine-directory'
class='header-anchors'>Setting Up the Engine Directory</h3><div
class="alert-message info"><p>It is very important to run at least <code>pio
build</code> once in your engine directory so that the project correctly
recognizes the version of PredictionIO that you are using. If you upgraded your
PredictionIO installation later, you will need to run <code>pio build</code>
again in order for the engine to pick up the latest version of
PredictionIO.</p></div><p>Create an engine directory from a template. This
requires that you install a template that you wish to start from or modify.
Follow template <a href="/start/download">install</a> and <a
href="/start/deploy">deploy</a
> instructions or go through the <a
> href="/templates/recommendation/quickstart/">Quick Start</a> if you are
> planning to modify a recommender. Make sure to build, train, and deploy the
> engine to make sure all is configured properly.</p><p>From IntelliJ IDEA,
> choose <em>File</em> > <em>New</em> > <em>Project from Existing
> Sources...</em>. When asked to select a directory to import, browse to the
> engine directory that you downloaded too and proceed. Make sure you pick
> <em>Import project from external model</em> > <em>SBT</em>, then proceed
> to finish.</p><p>You should be able to build the project at this point. To
> run and debug PredictionIO server, continue on to the rest of the
> steps.</p><div class="alert-message info"><p>If you are running on OS X, you

editing, IntelliJ should either refresh the project automatically or prompt you
to refresh.</p><h3 id='dependencies'
class='header-anchors'>Dependencies</h3><p>IntelliJ has the annoying tendency
to drop some dependencies when you refresh your build.sbt after any changes. To
avoid this we put any jars that must be available at runtime into a separate
empty module in the project then we make the main engine project depend on this
dummy module for runtime classes.</p><p>Right click on the project and click
<em>Open Module Settings</em>. In the second modules column hit
<strong>+</strong> and create a new Scala module. Name it pio-runtime-jars and
add these assemblies under the module dependencies tab and remember to change
the scope of the jars to <strong>runtime</strong>:</p> <ul> <li><p>
<code>pio-assembly-0.12.0-incubating.jar</code
></p><p>This JAR can be found inside the <code>assembly</code> or
><code>lib</code> directory of your PredictionIO installation

documentation assumes that you have a fully functional PredictionIO setup. If
you have not installed PredictionIO yet, please follow <a

IntelliJ for Engine Development</h2><h3 id='installing-intellij-scala-plugin'
class='header-anchors'>Installing IntelliJ Scala Plugin</h3><p>First of all,
you will need to install the <a
href="https://plugins.jetbrains.com/plugin/?id=1347";>Scala plugin</a> if you
have not already done so.</p><p>Go to the <em>Preferences</em> menu item, and
look for <em>Plugins</em>. You should see the following screen.</p><p><img
alt="IntelliJ Plugins"
src="/images/intellij/intelliJ-scala-plugin-09ee074a.png"/></p><p>Click
<em>Install JetBrains plugin...</em>, the search for <em>Scala</em>. You shoul
d arrive at something similar to the following.</p><p><img alt="Scala Plugin"
src="/images/intellij/intellij-scala-plugin-2-592c697f.png"/></p><p>Click the
green <em>Install plugin</em> button to install the plugin. Restart IntelliJ
IDEA if asked to do so.</p><h3 id='setting-up-the-engine-directory'
class='header-anchors'>Setting Up the Engine Directory</h3><div
class="alert-message info"><p>It is very important to run at least <code>pio
build</code> once in your engine directory so that the project correctly
recognizes the version of PredictionIO that you are using. If you upgraded your
PredictionIO installation later, you will need to run <code>pio build</code>
again in order for the engine to pick up the latest version of
PredictionIO.</p></div><p>Create an engine directory from a template. This
requires that you install a template that you wish to start from or modify.
Follow template <a href="/start/download">install</a> and <a
href="/start/deploy">deploy</a> instructions or go
through the <a href="/templates/recommendation/quickstart/">Quick Start</a>
if you are planning to modify a recommender. Make sure to build, train, and
deploy the engine to make sure all is configured properly.</p><p>From IntelliJ
IDEA, choose <em>File</em> > <em>New</em> > <em>Project from Existing
Sources...</em>. When asked to select a directory to import, browse to the
engine directory that you downloaded too and proceed. Make sure you pick
<em>Import project from external model</em> > <em>SBT</em>, then proceed to
finish.</p><p>You should be able to build the project at this point. To run and
debug PredictionIO server, continue on to the rest of the steps.</p><div
class="alert-message info"><p>If you are running on OS X, you will need to do
the following due to this <a href="http://bit.ly/12Abtvn";>known

editing, IntelliJ should either refresh the project automatically or prompt you
to refresh.</p><h3 id='dependencies'
class='header-anchors'>Dependencies</h3><p>IntelliJ has the annoying tendency
to drop some dependencies when you refresh your build.sbt after any changes. To
avoid this we put any jars that must be available at runtime into a separate
empty module in the project then we make the main engine project depend on this
dummy module for runtime classes.</p><p>Right click on the project and click
<em>Open Module Settings</em>. In the second modules column hit
<strong>+</strong> and create a new Scala module. Name it pio-runtime-jars and
add these assemblies under the module dependencies tab and remember to change
the scope of the jars to <strong>runtime</strong>:</p> <ul> <li><p>
<code>pio-assembly-0.12.1.jar</code></p><p>Thi
s JAR can be found inside the <code>assembly</code> or <code>lib</code>
directory of your PredictionIO installation directory.</p></li> <li><p>
<code>spark-assembly-2.1.1-hadoop2.4.0.jar</code></p><p>This JAR can be found
inside the <code>assembly</code> or <code>lib</code> directory of your Apache
Spark installation directory.</p></li> </ul> <p><img alt="Create empty module

key in SBT to the version of PredictionIO you have installed, so that Intellij
loads the correct JARS via its Auto-Import feature. Now, you can go ahead and
