 <p>This Guide helps you to do the release in Apache for ServiceComb projects.</p>

 <h2 id="pre-requisite">Pre-Requisite</h2>
 <p>To prepare or perform a released you MUST BE at least an Apache ServiceComb committer.</p>

 <ol>
   <li>The CI for the project should be green.</li>
   <li>Should have the version number for the project.</li>
   <li>Should have <a href="https://www.apache.org/dev/openpgp.html#generate-key">Sign Key</a> for <a href="https://www.apache.org/dev/release-signing">signing the release</a>, the keys should be published to public key server.</li>
   <li>Get familiar with the release settings in the parent Apache POM</li>
 </ol>

 <h2 id="maven-2-setup">Maven 2 Setup</h2>
 <p>As ServiceComb Java Chassis and Saga are using maven for the release, you should do some maven 2 setup before releasing these two projects.
 Before you deploy anything to the maven repository using Maven 2, you should configure your ~/.m2/settings.xml file so that the file permissions of the deployed artifacts are group writable. If you do not do this, other developers will not able to overwrite your SNAPSHOT releases with newer versions. The settings follow the <a href="http://maven.apache.org/developers/committer-settings.html">guidelines</a> used by the Maven project. Please pay particular attention to the <a href="http://maven.apache.org/guides/mini/guide-encryption.html">password encryption recommendations</a>.</p>

 <h2 id="major-steps-for-doing-service-center-release">Major Steps for doing Service-Center Release</h2>

 <p><strong><em>Make and Verify the Release</em></strong></p>

 <ol>
   <li>Clone the service-center code.
     <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>git clone https://github.com/apache/servicecomb-service-center.git
 cd servicecomb-service-center
 gvt restore
 </code></pre></div>    </div>
   </li>
   <li>
     <p>Create a Tag from the master branch based on the version number which needs to be released.</p>
   </li>
   <li>
     <p>Run RAT tool to ensure no license issues are there, follow the guide over <a href="https://github.com/apache/servicecomb-service-center/tree/master/docs/release">here</a></p>
   </li>
   <li>
     <p>Run the make_release.sh to make the release for windows and linux following the guide over <a href="https://github.com/apache/servicecomb-service-center/tree/master/scripts/release">here</a>.</p>
   </li>
   <li>
     <p>Last Step will make the releases in root folder.</p>
   </li>
   <li>
     <p>Run the releases of frontend and service-center in both linux and windows.</p>
   </li>
   <li>
     <p>Run the <a href="https://github.com/apache/servicecomb-service-center/tree/master/integration">integration test</a> on the release.</p>
   </li>
   <li>
     <p>If all the test passes then send the release candidate to peers to test in different machines.</p>
   </li>
   <li>Push the tag to master.</li>
 </ol>

 <p><strong><em>Sign the Release</em></strong></p>

 <ol>
   <li>
     <p>Once the tag is pushed then using the tag download the source code from git <a href="https://github.com/apache/servicecomb-service-center/tags">tag</a>.</p>
   </li>
   <li>
     <p>Sign the 4 releases(linux, windows, darwin, src) and checksum.</p>
   </li>
   <li>
     <p>Create a new directory <a href="https://dist.apache.org/repos/dist/dev/servicecomb/servicecomb-service-center/">Apache dev Release SVN</a> with release package name and release candidate number. (for example : if you want to release 1.0.0-m2 and this is the second attempt of the release then the folder structure will be <code class="language-plaintext highlighter-rouge">1.0.0-m2/rc02</code>)</p>
   </li>
   <li>
     <p>Upload the release to the directory created in last step.</p>
   </li>
   <li>
     <p>Download all the releases from SVN and verify the signature and checksum.</p>
   </li>
 </ol>

 <p><strong><em>PMC Approval</em></strong></p>

 <ol>
   <li>
     <p>Send the voting mail in <strong><em>dev@servicecomb.apache.org</em></strong> for 1PMC approval.</p>

   </li>
   <li>
     <p>Publish the result of the vote in dev@servicecomb.apache.org.</p>
   </li>
 </ol>

 <h2 id="major-steps-for-doing-java-chassis-release">Major Steps for doing Java-Chassis Release</h2>

 <p>Before release, make sure all apache issues are closed. Log in
  <a href="https://issues.apache.org/jira/projects/SCB">apache issue website</a>, click <code class="language-plaintext highlighter-rouge">release</code> and generate release notes.</p>

 <p><strong><em>Prepare the release code</em></strong></p>

 <p>clone java-chassis code to your development environment, change version to release version and push to github.
 Assume code version is <code class="language-plaintext highlighter-rouge">2.0.0-SNAPSHOT</code> and release version is <code class="language-plaintext highlighter-rouge">2.0.0</code>.</p>

 <p>Run:</p>

 <p>```shell script
 mvn versions:set -DgenerateBackupPoms=false -DnewVersion=2.0.0</p>
 <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>
 Then:

 ```shell script
 mvn clean install -Pit
 </code></pre></div></div>

 <p>If the build is successful, submit a PR and merge code after review.</p>

 <p><strong><em>Release maven artifacts</em></strong></p>

 <p>Prepare Linux environment, and make sure can upload artifacts to maven central.</p>

 <ol>
   <li>
     <p>Copy GPG keys to <code class="language-plaintext highlighter-rouge">~/.gnupg</code></p>
