<h2><a name="Release_Process"></a>Release Process</h2>
<p>There are two distinct sets of artifacts in two repositories that are typically released together: apache-streams and apache-streams-examples.</p>
<p>apache-streams artifacts include streams source code and convenience jars by module. </p>
<p>apache-streams-examples source code builds ready-to-run stand-alone examples as uber-jars.</p>
<p>Releases must be built and published in the following order:</p>
<ul>
<li>apache-streams</li>
<li>apache-streams-examples</li>
</ul>
<p>In the instructions below, ${project.name} should be one of these top-level repository aggregator pom project names.</p>
<div class="section">
<h3><a name="NOTE:"></a>NOTE:</h3>
<p>As a streams release manager, you probably want to use the release.sh and publish-rc.sh scripts in the root of apache-streams.</p>
<p>To perform a release manually, or to better understand what&#x2019;s going on, read the instructions below.</p>
<p>In either case, you&#x2019;ll need to first refer to <a href="/release-setup.html">Release Setup Information</a>.</p></div>
<div class="section">
<h3><a name="Common_Release_Steps"></a>Common Release Steps</h3>
<ol style="list-style-type: decimal">
<li>
<p>Environment setup for releasing artifacts (same for SNAPSHOTs and releases)</p>
<ol style="list-style-type: decimal">
<li>Use the latest Sun 1.8.x JDK</li>
<li>Use Maven 3.3.9 or later</li>
<li>Make sure the <a href="release-setup.html">Release Setup</a> steps have been performed.</li>
</ol></li>
<li>
<p>Prepare the source for release:</p>
<ol style="list-style-type: decimal">
<li>Cleanup JIRA so the Fix Version in issues resolved since the last release includes this release version correctly.</li>
<li>Update the text files in a working copy of the project root -
<ol style="list-style-type: decimal">
<li>Update the CHANGELOG based on the Text release reports from JIRA.</li>
<li>Review and update README.md if needed.</li>
<li>Commit any changes back to git</li>
</ol></li>
<li>Stage any Roadmap or Release landing pages on the site.</li>
</ol></li>
<li>
<p>Create a release candidate branch from master.</p></li>
</ol>
<p>X should start at 1 and increment if early release candidates fail to complete the release cycle.</p>
<div class="source">
<div class="source"><pre class="prettyprint"> git checkout master
git branch ${project.name}-${project.version}-rcX
git checkout ${project.name}-${project.version}-rcX
</pre></div></div>
<ol style="list-style-type: decimal">
<li>
<p>Verify the source has the required license headers before trying to release:</p>
<div class="source">
<div class="source"><pre class="prettyprint">mvn -Papache-release clean apache-rat:check -e -DskipTests
</pre></div></div></li>
<li>
<p>Do a dry run of the release:prepare step: </p>
<div class="source">
<div class="source"><pre class="prettyprint">mvn -Papache-release release:prepare -DautoVersionSubmodules=true -DdryRun=true
</pre></div></div>
<ul>
<li>The dry run will not commit any changes back to SCM and gives you the opportunity to verify that the release process will complete as expected. You will be prompted for the following information :</li>
</ul>
<div class="source">
<div class="source"><pre class="prettyprint">* Release version - take the default (should be ${project.version})
* SCM release tag - *DO NOT TAKE THE DEFAULT* - ${project.artifactId}-${project.version}-rcX
* New development version - take the default (should be ${project.version}-SNAPSHOT)
* GPG Passphrase
</pre></div></div>
<ul>
<li><i>If you cancel a release:prepare before it updates the pom.xml versions, then use the release:clean goal to just remove the extra files that were created.</i></li>
</ul>
<ul>
<li>The Maven release plugin checks for SNAPSHOT dependencies in pom&#x2019;s. It will not complete the prepare goal until all SNAPSHOT dependencies are resolved.</li>
</ul></li>
<li>
<p>Verify that the release process completed as expected</p>
<ol style="list-style-type: decimal">
<li>The release plugin will create pom.xml.tag files which contain the changes that would have been committed to SVN. The only differences between pom.xml.tag and it&#x2019;s corresponding pom.xml file should be the version number.</li>
<li>Check release.properties and make sure that the scm properties have the right version. Sometimes the scm location can be the previous version not the next version.</li>
<li>Verify signatures (<a href="#verify_signatures">Verifying release signatures</a>)</li>
</ol></li>
