| There are a couple of scripts that will take care of this although they need to be localized to your particular execution environment and you need to have authorization to put stuff where it needs to go. |
| These scripts are located at:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><a class="link" href="http://git.eclipse.org/c/jetty/org.eclipse.jetty.admin.git/tree/release-scripts" target="_top">http://git.eclipse.org/c/jetty/org.eclipse.jetty.admin.git/tree/release-scripts</a>.</li></ul></div><p>To localize the scripts to your environment:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">ensure you have "curl" installed</li><li class="listitem">edit the scripts and replace all ssh login lines with your own login id</li></ul></div><p>Once these are setup you can deploy a release to eclipse with the following incantation:</p><div class="screenexample"><pre class="screen">$ ./promote-to-eclipse.sh 9.0.0.v20130322</pre></div><p>Each of these scripts will download all of the relevant files from maven central and then copy them into the correct location on eclipse infrastructure. |

| Maintaining the conventions we use on the site will allow all <span class="emphasis"><em>stable</em></span> links to be stable and not needed to update to the latest major Jetty build version:</p><div class="screenexample"><pre class="screen">$ ssh <user>@build.eclipse.org |
| $ cd ~downloads/jetty/ |
| $ rm -Rf stable-9 |
| $ cp -r <version> stable-9 |
| $ ./index.sh</pre></div><p>This needs to be done for all Eclipse Jetty releases (regardless of version). In addition we have to work to reduce the footprint of jetty on the primary eclipse download resources so we want to move older releases to the eclipse archive site.</p><div class="screenexample"><pre class="screen">$ cd ~/downloads/jetty |
| $ mv <old release> /home/data/httpd/archive.eclipse.org/jetty/ |
| $ ./index.sh</pre></div><p>Periodically we need to do the same for the osgi P2 repositories to keep the size of our downloads directory at a reasonable size.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="_building_an_osgi_p2_repository"></a>Building an OSGi P2 Repository</h3></div></div></div><p>Most of the jetty jars are also osgi bundles, plus we release some specific bundles that <a class="link" href="framework-jetty-osgi.html" title="OSGI">integrate jetty closely with osgi</a>. |
| To do this, we use a Hudson job on the eclipse infrastructure. You will need to have permission to access <a class="link" href="https://ci.eclipse.org/shared/view/Jetty-RT/" target="_top">https://ci.eclipse.org/shared/view/Jetty-RT/</a></p><p>There are Hudson jobs that build osgi p2 repos for each of the major releases of jetty:7 (jetty-rt-bundles-7), 8 (jetty-rt-bundles-8) and 9 (jetty-rt-bundles-9). |
| You will need to start a manual build of the job that matches the version of jetty that you are releasing. |
| You will be prompted to supply some parameters to the build:</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">pack_and_sign</span></dt><dd>By default, this is ticked. Leave it ticked.</dd><dt><span class="term">jetty_release-version</span></dt><dd>Enter the version number of the release, eg 9.2.6.v20141205</dd><dt><span class="term">force_context_qualifier</span></dt><dd>Leave this blank.</dd><dt><span class="term">set_pom_version</span></dt><dd>Enter the major.minor.point release number, eg 9.2.6</dd><dt><span class="term">delete_tycho_meta</span></dt><dd>This is ticked by default. Leave it ticked</dd><dt><span class="term">BRANCH_NAME</span></dt><dd>This is not the branch of the jetty release. Rather it refers to the branch structure of the project that drives the jetty p2 release. |
| It will already be set correctly for the selected job, so don’t change it unless you have an extremely good reason.</dd></dl></div><p>Once you have supplied the necessary parameters, the build job will commence and the bundles and update site zips will generated and automatically placed in the <code class="literal">/home/data/httpd/downlaod.eclipse.org/jetty/updates/jetty-bundles-[MAJOR.VERSION].x</code>, where [MAJOR.VERSION] matches the major version number of the jetty release you are doing. |
| These files will then be visible from <a class="link" href="http://download.eclipse.org/jetty/updates/jetty-bundles-" target="_top">MAJOR.VERSION</a>.x, where [MAJOR.VERSION] corresponds to the major version of the jetty release you are doing.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="releasing-documentation"></a>Release Documentation</h3></div></div></div><p>There are two git repositories you need to be aware of for releasing jetty-documentation.
