<div class="paragraph">
<p>The N4JS IDE, headless n4jsc.jar, and the N4JS update site is being built on the Eclipse Common Build
Infrastructure (CBI). For this purpose the N4JS project is using a dedicated Jenkins instance, referred
to as a "Jenkins Instance Per Project" (JIPP) in Eclipse CBI documentation. At this time, the N4JS
project&#8217;s JIPP is running on the "old" infrastructure, not yet using docker. This will be migrated
at a later point in time.</p>
</div>
<div class="paragraph">
<p>The N4JS JIPP is available at: <a href="https://ci.eclipse.org/n4js/" class="bare">https://ci.eclipse.org/n4js/</a></p>
</div>
<div class="paragraph">
<p>The nightly build performs the following main steps:</p>
</div>
<div class="olist arabic">
<ol class="arabic">
<li>
<p>compile the N4JS implementation,</p>
</li>
<li>
<p>build the n4jsc.jar, the IDE products for MacOS, Windows, Linux, and the update site,</p>
</li>
<li>
<p>run tests,</p>
</li>
<li>
<p>sign the IDE product for macOS and package it in a .dmg file,</p>
</li>
<li>
<p>deploy to n4jsc.jar, IDE products and update sites to Eclipse download server (i.e. download.eclipse.org),</p>
</li>
<li>
<p>move all artifacts older than 7 days from download.eclipse.org to archive.eclipse.org.</p>
</li>
</ol>
</div>
<div class="paragraph">
<p>Details about all the above steps can be found in the Jenkinsfile <code>eclipse-nightly.jenkinsfile</code>, located in
the root folder of the N4JS source repository on GitHub.</p>

<div class="ulist">
<ul>
<li>
<p><code>Asciispec</code> is used to compile the source N4JSSpec Asciidoc into a single large <code>N4JSSpec.html</code> file which contains all the chapters. The use of the custom parameter <code>-a eclipse-help-mode</code> indicates that a special header and footer styles as well as CSS style should be used (i.e. no table of content menu, no download links etc.). Here, we are using the possibility provided by Asciidoctor to configure header/footer as well as CSS style via parameter <code>:docinfodir:</code> and <code>:stylesheet:</code>.</p>
</li>
<li>
<p>Our custom tool <code>Chunker</code> splits <code>N4JSSpec.html</code> (and other documents) into multiple chunked HTML files, each of which corresponds to either the <code>index</code> file or a chapter. It automatically re-writes internal links.</p>
</li>
<li>
<p>Another custom tool <code>EclipseHelpTOCGenerator</code> takes to Docbook file <code>N4JSSpec.xml</code> and generates an XML file describing the table of content (TOC) in the Eclipse format. This TOC file references the chunked HTML files above.</p>
</li>
<li>
<p>Another custom tool <code>IndexTocGenerator</code> takes to Docbook file <code>N4JSSpec.xml</code> similar to <code>EclipseHelpTOCGenerator</code>, but it generates an HTML fragment which can be embedded into the <code>index.html</code> page generated by the <code>Chunker</code> (Thus it has to run before the Chunker in that case).</p>

<p>Bump versions of all dependencies mentioned in file <code>N4JS.setup</code>:</p>

<ol class="loweralpha" type="a">
<li>
<p>Update all labels that refer to the version of the Ooomph setup (search for "label!" to find them).</p>

<li>
<p>Choose a new Eclipse version and define this in <code>N4JS.setup</code>.</p>
</li>
<li>
<p>For those other dependencies <em>that come with Eclipse</em> (e.g. EMF, Xtext) find out which version matches the chosen Eclipse version
and define that version in <code>N4JS.setup</code>.<br>
Tip: use the contents list of the SimRel you are targeting, e.g. <a href="https://projects.eclipse.org/releases/2019-03" class="bare">https://projects.eclipse.org/releases/2019-03</a></p>
</li>
<li>
<p>For those other dependencies <em>that are available via the Eclipse Orbit</em>, find out which version is the latest version available in
the Orbit and define that version in <code>N4JS.setup</code>.<br>
Tip: contents of the Eclipse Orbit can be found at <a href="https://download.eclipse.org/tools/orbit/downloads/" class="bare">https://download.eclipse.org/tools/orbit/downloads/</a><br>
(choose the correct link for the chosen Eclipse version!)</p>
